Move and Optimize Windows Vista's Paging File

This guide shows you how to optimize Windows Vista’s paging file by moving it to a separate hard drive or by using 2 page files for maximum performance.


Windows Vista has what is called a Paging File that is located on the hard drive. The paging file acts like additional RAM. If your computer runs out of RAM Windows Vista uses it’s paging file as an alternative to the RAM.

Since a computer’s hard drive controller can read and write from more than one hard drive at one time moving the paging file to a separate hard drive than Windows Vista is installed on improves your computers performance.

Instead of reading and writing system, program files, and your paging file on one hard drive you can move your paging file to a separate hard drive. With your paging file on a second hard drive the load is split between reading and writing system and program files and reading and writing the paging file.

This guide shows you how to optimize the paging file for maximum performance.

Things to Know

Before you start messing with your computer’s paging file there are things you need to understand so you don’t break your computer.

  • Your computer must have a paging file. Windows Vista and most software rely on the paging file even though your computer has plenty or memory.
  • The recommended size of the paging file is 1.5 to 3 times the amount of RAM you have.
  • If you move the paging file, it should always be moved to a different physical hard drive. Never use a separate partition on the same hard drive as the C: drive. This will slow your computer down.
  • You can have 2 paging files. Each paging file must be on different physical hard drives though. An example would be a paging file on your C: and E: drives.

Move Windows Vista’s Paging File

In this example I’m going to move the paging file from its original location on the C: drive to a separate hard drive called the E: drive.

  1. Right-click Computer in the Start Menu.
  2. Select Properties.
  3. Click Advanced system settings on the left side of the System window.
  4. Click the Settings button in the Performance section of the Advanced tab.
  5. Select the Advanced tab in the Performance Options window.
  6. Click the Change button in the Virtual memory section.
  7. Uncheck Automatically manage paging file size for all drives.


  8. Highlight the C drive, select No paging file, and then click the Set button. Ignore any warnings you receive.
  9. Select the drive you want to move the paging file to, select system managed size, and then click the Set button.
  10. Click OK and then restart your computer to apply the changes.

Use 2 Paging Files for Maximum Performance

Since the hard drive controller on your computer can read and write to more than one hard drive at a time it’s possible to have 2 paging files. It’s very important that the two paging files are on separate hard drives and not different partitions on the same hard drive.

In this example I’m going to setup a paging file on both the C: and E: drives for maximum page file performance.

  1. Right-click Computer in the Start Menu.
  2. Select Properties.
  3. Click Advanced system settings on the left side of the System window.
  4. Click the Settings button in the Performance section of the Advanced tab.
  5. Select the Advanced tab in the Performance Options window.
  6. Click the Change button in the Virtual memory section.
  7. Uncheck Automatically manage paging file size for all drives.


  8. Highlight the C drive, select system managed size, and then click the Set button.
  9. Highlight the second drive, select system managed size, and then click the Set button.
  10. Click OK and then restart your computer to apply the changes.

    Doesn’t it speed up performance to move the paging file to a different partition, even if that partition is on the same physical drive?

    • LarryPTL says:

      Moving a swap space to a different partition on the same hard drive will not speed things up. In fact, it could slow things down. The reason is that the read/write heads will have to travel from the portion of the disk drive allocated to the boot partition (normally your ‘C’ drive) to the portion of the disk drive allocated to the partition where your swap space is located, and back again. This takes time, and usually more time than just moving around within the same partition.

  2. Ste says:

    ava – have you read this page? Well the answer is no, it will slow things down as the read/write head has to move all over the place on the drive.

  3. Mike says:

    If your page file is system managed and on the same partition (C:\), then the swap file may become fragmented, decreasing performance. It’s not all black and white.

  4. Andrew says:

    I have two partitions on the same hard drive. I use the D: drive for storing games and the C: drive for other things. I have a user managed paging file on both drives. How can I remedy this only giving high performance to the D: drive?

  5. Jon says:

    What about 3 paging files? I have 2 10k RPM 150Gb WD Raptors in a hardware raid 0 for my OS and installed applications, as well as 2 500Gb 7200.10 Seagate Barracuda’s. As I don’t have Vista Ultimate, no striping the 2 500Gb drives. My mobo uses a SiliconImage Sil4723 chip with a jumper for the hardware SATA raid, but NVRAID supports up to 7 drives in RAID mode (5 additional SATA and 2 IDE). I may look into using that for striping my 2nd two drives, but… in the meantime would it be more beneficial to have 2 paging files on the barracudas, or 3 total paging files?

    I also have 4Gb of memory and 4Gb ReadyBoost, so the swap isn’t really that needed I guess.

    Also, the Raptors are not SATA II, so they only run a 1.5GBs, but they are much faster in terms of RPM. Would it still be better to keep then swap files off the main OS/apps drive? Or am I just pondering minor improvements.

    Sorry this belongs in the forum, but I started it here, was not meant to be this long.

  6. Brent Trahan says:

    Wow, that’s one hell of a setup Jon. 3 paging files wouldn’t hurt but I think you won’t notice a difference with all of the horsepower you already have.

  7. Jon says:

    Yeah, I like tweaking things though. The more performance I can get with my hardware, the better.

  8. Aakash says:

    Is it still recommended to set the paging file to a static number? Back in XP era, to avoid fragmentation issues, it was recommended that the paging file’s min and max limits were set to be the same to avoid having the paging file constantly shrink and grow. Is it still recommended to keep the paging file’s size static in Vista also?


  9. Brent Trahan says:

    It’s best to leave the page file size up to Windows. It’s been programmed to configure the page file at its optimal settings based on your computer.

  10. Dean Sinclair says:

    Sorry to butt in here with a burst of know-it-all-ness, but Aakash is absolutely correct. If you set the min and max size of your pagefile.sys the same, it will never be fragmented (that’s if you put it in a non-fragmented spot to begin with) therefore increasing load time (because it decreases the amount of times the physical reading head [almost like on a record player] needs to jump around the hard drive).
    I defragmented both my hard drives, in fact C drive just finished then, and now I’m going to put my pagefile on both hard drives (making the min and max size the same) and Windows will automatically create them the closest to the outer ring of the HD’s as possible (defragmenting gets files that are already where I want my pagefile and moves them so they’re next to their respective folders for faster loading). Once I’ve set them and I restart the computer, it’ll delete the old ones at shutdown and boot up with 2 new optimized (NON resizing and fragmenting) pagefiles! Try it and see if you notice a difference, but it’s highly reccomended. ;)

  11. Araknis says:

    page files suck
    the random access time of hard drives suck
    so Y would u want
    USB has fastest random seek other then ram is y flash drives are made
    anytime your computer has to read info from your harddrive and not your ram its going really slow dont kid yaself lol even in 20 years HD will be lucky to have that sort of random access time.

    What speeds up a computer a bigger processor and more ram not a bloody pageing file LOL

  12. Araknis says:

    USB rdy drives store info on them in small parts like 4kb max when your computer need to access that info it can get it from either the USB or the HD,if it gets it from the USB would take about 0.08sec to find and caopy on an average rdy drive where as your HD would take at least 2 secs moving the head to the point of the disc + spin up the disc and read it, now think if your computer has to read alot of those kind of files, what is your HD is doing ill tell u a hell of alot of random seeking it cant handel :) and dont come back with but my HD runs at 3GB and a USB can only run at 12-25Mb theres no way its faster ill laugh my arse off :P

  13. Dave says:

    Setting your page file to a static size is much better than letting Windows manage the size. For one there are extra resources used to resize the page file (Disk and CPU), if the pagefile needs to grow there is a slight delay in the process. IF you have a 500GB HD, why not set the pagefile to 16GB and not concern yourself ever again with fragmentation or size issues? 16GB on a 500GB disk is a small price to pay.

    As for using a second drive, it will obviously be better in many aspects. But, if they are IDE on the same cable you are not going to see a huge performance gain, perhaps even a hit. Also, I could use a second drive though – if the second drive is slower than the first drive I may be defeating myself!

    Set the page file to a fixed size on a separate partition, or a separate disk from your programs and OS. Set your OS on a seperate drive or partition from your programs aswell. – There is a reason why when I install Linux it follows these same principals.

    The OS partition/drive will only be fragmented from OS changes, the program – the programs, and the Pagefile will not become fragmented on it’s separate location. I also put my downloaded multimedia content on a separate partition, as it is constantly changing, yet does not matter as much if it fragments.

    Sure, it would be wiser to set these four partitions on four seperate disks with independent I/O systems. But, if you have that kind of money why not buy a solid state drive! lol

  14. Fred says:

    Mr. Know-It-All, here.

    I’ve been working with Windows since 3.1. I manage servers and workstations for a HUGE organization.

    If you have a second drive, put the page file there and set the size static to 1.5 times the size of your RAM. Windows will only address 1.5 times the physical RAM. If you don’t set the page file to static, it will fragment and you can’t de-frag it. That’s the way we do it on all out computers.

  15. Todd says:

    Testing shows pretty much what others are saying, though not at all sure about the 1.5 number, any references for that?

    Partions – First will be put on outer rim of disk, this is the fastest area, anywhere from 20% to 50% faster dependent on disk

    Paging – Static, defragmented, no question this will decrease thrashing, and if NOT in it’s own partition will stop fragmenting

    Physical Drive 1,2 Velociraptors
    1st Partition 3 x Memory
    2nd Partition OS, etc
    Physical Drive 2,3,4,5 – RAID 0 (Seagate 1.5TB x 4)
    1st Partition Scratch for CS (Photoshop) = 10-20% of disk size
    2nd 3 x Memory
    3rd 4TB for DATA
    4th Emergency Space

    It’s true that true Physical drives would be better, but the truth is for data/applications it’s a load once operation after which paging takes over where memory fails, after which seek’s etc are confined to the scratch disk and paging file (though that’s rare for it to hit the paging much since I have 12GB on an i7 system) RAID 0 increases this dramatically (yes everything is backed up nightly to an alternate setup)

    Anyway real world testing showed me this was fastest, but not sure about the need for 2nd paging file, havent stressed it enough

  16. bill says:

    I stumbled in here looking for some answers to moving my page file to an SSD Expresscard which uses an internal USB port.
    Unfortuately your directions don’t work for me. When I select no page file for the C: drive and set the ssd as the page file- a reboot shows all page files are disabled. I cannot get the paging off the C: drive. It has to be there for any other page files to be enabled. so what’s with that??

  17. TSnor says:

    re: “…to moving my page file to an SSD Expresscard which uses an internal USB port. … ”

    Yeah, it won’t do that. I’ve tried it too. The best you can do is (1) buy a flash drive that looks like a SATA drive (expensive) or (2) use readyboost and a low-latency high bandwidth flash card.

  18. PdP09 says:

    I recently bought a CF to SATA adapter for $5 (new), for connecting a CF card to a SATA connection on the mobo. It says it is compatible with CF I/II, needs no drivers, can support data transfer up to 1.5Gb/s and can be the primary boot device. I also have a CF to IDE adapter, also $5.
    I’m still experimenting with them – I still need to load puppy linux on my lowly 4GB card.

  19. bill says:

    I set my page file to a small size on the c: drive and made a 4Gig page file on the SSD express card. I’m not sure what that really gives me in a perfomance boost. I have a readyboost drive of about 4 Gigs also on that express card but from what I read it won’t give me much if any boost since I have 3 Gigs memory. I may just delete it.

  20. Brian says:

    I just built a new Vista 64 bit system. Intel i7 quad core processor. 2TB Storage (RAID 10)

    I also have a 32G Solid State drive which I thought I’d put the page file on.

    Anyone see any issues with this?

    • JGerm30 says:

      I’ve read that SS drives read real fast, but they don’t write any faster than a good HD. Also, I thought that each location on SS drives has a limited number of writes. I am installing Vista on an SS drive and putting the page file on an HD. Will let y’all know how it turns out.

  21. Brent Trahan says:

    Brian, I’m impressed by the specs of that new PC. I’m not sure if that solid state drive will be much faster. Why don’t you try and let us know.

  22. Aprinto says:

    My Systems :
    – OS Vista Bussiness
    – HDD 1 parted to Windows and Program files (2 partitions)
    – HDD 2 parted to data and temp dir (2 partitions)
    – HDD 3 not parted for multimedia
    – USB 1 flashdisk 8GB to readyboost 4GB, remain 4GB free space.

    Can I speedup my PC if I move pagefile to remain USB 1 space?

    Thanks a lot

  23. Tony says:

    I found this page helpful as Vista will not otherwise reduce the size of the Vista partition on my system below 85GB, even though it uses << 20 GB. Apparently the swap file/paging file was stored around the 85GB location in the partition, and the partition could not be shrunk past it.

    I did read this “Never use a separate partition on the same hard drive as the C: drive. This will slow your computer down. “, and wondered if they were wrong or if you could comment.


  24. Brent Trahan says:

    You should never put the page file on a seperate partition on the same hard drive as Windows is installed on.

    If you do, your hard drive’s arm will have to move from one end of the platter to the other constantly if the page file is being used. This will slow down your computer.

    • Gogo says:

      I do not have a second hard drive, i just want to move the page file grom the vista partition to my second partition to allow shrinking of C then move it back to drive C. Is that ok?

  25. Blake says:

    I did what was suggested above to set an additional page file on an addition drive in PC.Now my pc won’t load past boot,setup page. I don’t want to restore. But what else is there to do?Thanks

  27. Tizbot says:

    Hi there. I am running Vista Home Premium 64 bit on a Q6600 with 8gigs of ram and no paging file. I have been running this way for about two months now. I have not quantified it through any benchmarking, but things seemed a bit snappier after I removed my paging file. I did have it on the same drive as my operating system though. I have not had any problems with my system since eliminating my paging file. I use my computer mostly for gaming and home entertainment (converting video formats, burning DVDs etc.) and some photo editing. Ram is so cheap these days that getting an extra 4gigs and foregoing the paging file makes great sense.

  28. Carl says:

    I have the same problem as Tony, I cannot shrink Vista’s partition below 214GB because of the location of unmoveable system files, most likely the page file. For years I have heard that the page file should be placed where the disk spins the fastest. How do you move the page file to a spcific area of the drive without dropping it into a separate partition?

    In responce to Fred,
    he gave sound advice, but for those who need it, PageDefrag can defrag paging files and Registry hives. It is one of Mark’s Sysinternals tools, here:

  29. Kreationz says:

    You can put it on a separate partion on the same drive. But it should be as follows for performance.
    Partion 1 5Gb: PageFile only this ensures it is place at the outside of the platter and is never fragmented (the main reason for taking away windows management).(Windows managed size it won’t go above 4Gb in Vista, but windows doesn’t like over 80% of a drive used hence 5Gb.)
    Partion 2: Os and Programs (and everything else if you want. Defrag immediately after installing the os and moving the page file.)
    Partion 3: Storage (Optional for organization and easy OS reinstalls, but this will be the slowest partion)

    • LarryPTL says:

      Cool way to divy things up.

      I use two HDDs in my computer. The first drive contains my OS on the first partition (fast), the second drive uses the first partition for swap space (and only swap space goes there, which means it never gets fragmented!). The other partition on the 2nd drive contains all of my working files.

      The reason for keeping the working files on the 2nd disk drive is that the program file accesses won’t demand time from the same set of read/write heads that handle the data files.

      On a periodic basis I use a DOS batch file to back up my working files onto the 2nd partition of the first drive. The command is:

      XCOPY D:\*.* K:\*.* /v /s /d /y /c /f /g /h /r /x

      Every now and then I also plug in an external drive and use the same command to save all my data files to it. It doesn’t stay connected for very long, just long enough to save everything. That way, if a virus gets on my computer and trashes both hard drives, I still have a working copy of my files (except for perhaps the last week’s updates) kept from harm’s way.

  30. cisco says:

    The slowest part of a computer is the hard Drive so if you want a faster computer just get a faster Hard drive.
    then ofcourse a good video card and processor and memory.

    • Bob says:

      The fact that the hard drive may be slower than other parts of the computer does not mean you should upgrade it. Very misleading statement, if you are being serious. A computer with 1GB and an old slow hard drive might be much faster than a computer with 512MB and an extremely fast new hard drive, just because it isn’t even using the hard drive as much. It really depends on the circumstance. Maybe you were just joking though.

  31. cisco says:

    It is widely known that Hard drives are the slowest part of a computer because it has moving parts,
    Processors, memory and video cards dont have muving parts that need to move to perform.

  32. Dwindle says:

    This guy has no idea what he’s talking about. Having no paging file is always better than having on one at any size, no matter what. I haven’t had one since 2003 and have yet to see a problem. Moving the paging file to another partition is a total and complete waste of time. If anything, use a flash drive or separate hard drive if you don’t have enough memory to live without a page. Note: Linux machines often benefit from a paging file or partition, but it’s not necessary. If you use a Mac, you’re an idiot and have no idea what we’re talking about anyway.

  33. Kamairozs says:

    Wow page file up roar. heheh Basic first please.

    Windows only uses a page file if it runs out of physical memory. Example; Running too may programs at one time. Once it uses up all the physical memory in the machine it then creates a space on the HD (Hard Drive) to swap the information in and out of as it need that information. This space is know as a “Page file/Swap file” or paging system.

    If windows is left to manage the page file it is constantly adjusting the size depending on how much space it needs. So if it has to move other files to increase the size of its page file it does. This will cause your machine to run slower as windows is constantly adjusting the page file.

    Reading and writing to physical memory is much faster than accessing a HD hands down. However if that memory chip is on a flash drive you are limited to the bus speed on the mother board and the through put to the usb port.

    An important thing to remember is that windows only uses a page file if and only if it runs out of physical memory. So if your OS can see 8GB of RAM (Random Access Memory) and you have 8GB RAM installed you will probably never use a page file on the HD as you will never exceed more than 8GB memory loading the OS and running your programs.

    Static (making the minimum and maximum size of a page file the same) page files on seperate HD’s seem to work well. However it is important to know if you exceed the static size using some super uber 3D CGI software windows will increase the size of your static page file it will not error and shut windows down. It will increase the size as needed once it is done it will reset the static size back to what it was.

    The only time you will get a “Out of Virtual Memory” error is if your HD has no free space left on it. There is no room left for windows to swap files on and off the HD. Hence “Virtual Memory” its not memory at all it is HD space.

    Moving your page file and making it static will only get you so far. If you move it to another HD, or flash drive you are still limited to the through put of the cables or bus that is connecting that device. You will see slight improvements doing these things.

    If you realy want to see marked improvement then increase the ammount of physical memory in the machine. Increase the ammount of physical memory from 1Gig. to 2Gig. or 2Gig to 4Gig. You are only limited to how much memory your OS (Operating System) XP, Vista, Win7, Linux, Mac etc. will see and how much memory your motherboard will hold.

    Don’t let people BS you with “Front side bus” speed and all that hype. Like those video card and processor guys. “My processor has a front side bus speed of 5 bazillion gigs a second” Yea well that is nice 8) the fastest mother board on the planet only has 64bit bus …. so that information can travel as fast as it wants too in the processor, but once it leaves the processor or memory to go to another device connected to the mother board it’s only going at 64bits a second. A 64 bit bus will only cary 64 bits of info a second duh….. Anyway I hope this helps some of you guys accomplish what you are tyring to do.

    • Paul Penrose says:

      Where do you get this 64 bits per second nonsense? If computers were that slow you would never get things done. First off, the external bus size and the internal bus size for a processor do not have to be the same. But just for fun let’s assume they are. The rate at which bits are transferred is determined by both the data bus width and the cycle rate of the bus. But I can prove it’s much faster than 1 per second. Try this experiment: load your word processor. Then hit file | load, and select a 1mb file. Hit OK. How long did it take to load that 1mb file? If your processor can only access data a 64bits/sec then it should have taken 1mb/64 seconds or 4.55 hours. What, you say it took a second or less? Gee, maybe the bus speed really is megabytes per second.

      • Dax Bertumen says:

        He is right with the fastest motherboard capacity of 64-bit. Actually it’s not motherboard capacity, it’s just how things work inside ur pc, complimented by the OS that you use. but that doesnt mean that it’s 64bit/sec! hell no! it means that one second is devided into 64 timeslots.. and in each timeslot, the data will travel at a speed frequency depending on the Bus speed of the mobo. 800 or 1337 ghz or whatever. multiply it by 64 timeslots in a second, well the figures are unimaginable. However again, it would depend on how fast your hard drive or your memory or any other peripherals can be accessed divided by the time (in seconds) it will take to access the whole storage area. hence the mathematical equation per second, 12MB/sec, 32MB/sec..etc.

        so no matter how fast ur processor is, The sad part will always depend on your storage. (HD,RAM,Vid mem,USB…ect) but of course a fast processor would be better since the amount of workload used by the faster processor on a specific task (let’s say a single picture frame) would be lesser than that of a slower processor. but lets say they both read/write at the maximum capacity of a storage device, load times are the same for that specific program, however the faster cpu will have the benefits of more task performed at a lesser power output, hence a faster load for all start-up programs when you boot your computer.

        everybody gets it? 64-bit means 64 timeslots ok? means

        N x BS in giga or megahertz x 64 / 1second = Y mhz or ghz/sec
        Y – speed of your storage = Z

        N= whatever amount of data processed by processor
        BS= Bus speed (do not confuse with Bus width)
        Y= the speed at which data will travel through your 64-bit mobo
        Z= speed at which the computer can execute another task

        therefore going back to paragraph 2, the more the Z the faster it is to load multiple programs at once (just like during start up and like what your computer is normally doing everyday) and the lesser processor load is required…

        Ughh.. why did i even bother explaining?

  34. Mr K Jones says:

    Hello, i hope some one can help.
    I have 2 physical drives C and E. Drive C is partioned into 2 C and D, I have Win Xp installed on C and Win 7 installed on D. Now the pagefile for XP in on E the second drive. and the pagefile for Win 7 is on the installed OS partion D. My question is there a way i can use the second drive E for both pagefiles?

  35. Harvey says:

    I haven’t tried this for myself yet, but the advantages make sense to me. The best being fragmentation control over the long haul, just like you think of the data partition. Some say “don’t put page file on separate partition\same drive as os”. Could it really slow things down that much? Atleast the page file isn’t fragmented across the entire drive down the road which would slow it down even more eventually. Or, correct me.
    I also question the notion that 8g ram is more than enough to ever need a paging file. I am running Vistax64 8ram and still run into freezes under multi application pressure sometimes. Wouldn’t having an optimized paging file setup atleast help with that a little? I dunno. Get a fast processor, max out ram, upgrade video card… why not tweak paging file?

    • Dax Bertumen says:

      To answer your question Harvey, we have to take a look into the task manager of your computer. Close all applications leaving all the standard start-up programs running. Meaning the “application tab” on your task manager should not contain any running program at all and do not touch the processes tab. Then look at the physical memory usage history under the “performance tab”. Should the physical memory usage be > or = to 50% of what amount of RAM you currently have just by running your basic processes, then definitely you will need to optimize your paging files. which is perfect if set around 2.5 times your current RAM. And of course following all the drive specifics the people above mentioned. if it doesnt go beyond 50% then I suggest you leave windows to determine the page file for you. if it is below 50% and you still experience freezes, then it’s either processor, vid card or HDD incapacity. Quad core cpu’s are perfect for multi-applications no matter the clock speed because there are four cores that work on processing an application thread or multiple threads of an application. for multi-application on vista, it is best to have at least 9600GT vid card or equivalent. 9800GT or 8800Gt and higher will be better of course. And these cards will cost only like $100 today. It requires mid range VidCards since Vista is very graphic processor and memory demanding, that’s why it takes a huge chunk off of your RAM to allocate for video memry even if your video card memry is already 1Gig. For HDD the standard 7200RPM will do and preferrably with extra 16MB or 32MB Cache, making sure that when you run the computer the HDD is not making any creaking sound and it’s dead silent. If it makes a sound, it’s probably too fragmented or physical parts are damaged. To sum it all up, vista is an OS that eats a lot and gives a lot, like a fattening pig or sheep or whatever local livestock you can relate to. So you better invest more for a bountiful harvest. :-D

    Many knowledgeable folk seem to be here.
    I am sure that I have read somewhere that the outer rings of an HD are faster than the inside ones.
    If I have the operating system on one drive (my C:)and have placed the swap file on the second drive (which is partitioned into E: & F:)
    SO which partition shoud I tell the swap file to go on the second drive, the E or the F.
    In other words, I guess I am asking what sequence/order that the OS (XP still) places the partitions. Does it start sequentially at those faster rings with E: and then progress to the F: n the closer to centre rings?

      In your case, place it on partition E: Put the paging file on the 1st partition of each hard disk. Do not put paging files on other partitions of the disk aside from the 1st. To best determine which is the 1st partition, go to administrative tools, then computer management and the storage. You should see both your hard disk and their partitions.

      The size of the paging file should be around 2.5x the amount of RAM you have. In case you have 4gig, 1 times the size would suffice.

      We have the same set-up. I have 2 HDs as well both partitioned in two.I used to boot vista at around 15 seconds. after I added another disk and added paging files, i now boot at around 6-7 seconds. Though the number of start-up programs could contribute to boot time, I have the same start-up programs as before and it improved dramatically around 50%. Programs also respond much faster to clicks.

    i have windows 7 ultimate with 1gb ram. the issue is the low memory error comes repeatedly. the settings i make to the page file console some how wash away on next boot and the console shows blank space in the area designated to show the size of page files. can the page file be forced edited in a text editor as i believe the windows based console is not working. i have been optimizing for programs and use values much above the min and max allowed in the custom size.

    So the mini-partition that windows set up for the boot sector files gave me an idea, make a similar pagefile only partition at the beginning of my second hard drive just for the pagefile, that way it can never get fragmented or mixed up with all my files. Trouble is, who wants a 12GB drive E: sitting around with just a pagefile on it? If that doesn’t bother you fine, it bugged me, so I mounted the 12GB partition as a folder C:\Pagefile. Now the problem is by default, pagefiles always go into the root directory of whichever drive they are assigned to. Into the registry we go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management where you will find a multistring called PagingFiles. The default value is ??:\ I edited that to ??C:\Pagefile\ Reboot and your computer will move the pagefile to C:\Pagefile\pagefile.sys (remember C:\Pagefile is actually an partition at the start of hd01). Neat-o.
