What is the Application Experience (AeLookupSvc) service?

An explanation of the Application Experience (AeLookupSvc) service in Windows 7.

What does the Application Experience (AeLookupSvc) service do?

The application experience service was first introduced to consumer PCs with Windows Vista. Windows Vista was a big change from XP when it came to software and driver compatibility. The application experience service watches in the background when you install software or a new device. If the installation fails, it pops up and asks you if you want it to try installing it again using workarounds it’s been taught by Microsoft.

Application Experience (AeLookupSvc) service details

  • Service name: AeLookupSvc
  • Description: Processes application compatibility cache requests for applications as they are launched.
  • Path to executable: C:\windows\system32\svchost.exe -k netsvcs
  • Startup type: Manual

Does my computer need the Application Experience (AeLookupSvc) service?

Your computer doesn’t need the Application Experience service, but it sure makes installing old software and devices easier in Windows 7.

Should I disable the Application Experience (AeLookupSvc) service?

First off, I have to say that it’s best to leave service optimization up to Microsoft. With that said; if you have a new Windows 7 PC and all of your devices and software are the latest and greatest, I don’t see why you shouldn’t disable this service.

    After trying to figure out what was causing a momentary flicker in Chess Titans on Windows 7(doesn’t happen in Vista), I disabled many unneeded services and what I found out is setting Application Experience to automatic stopped the behavior. It is set to manual by default. If I disable the service, then browsers aren’t allowed to download any files to the desktop. Another guy on the net had the same problem, so this is a required service in 7 but not in Vista.

    “best to leave service optimization up to Microsoft”. Seriously? Do you work for Microsoft? Leaving service optimization up to Microsoft is like expecting the government to balance our budget and get us out of debt. When hell freezes over. In other words, NEVER!

    Disabling the Service can lead to problems. Executables Files are locked for a while (1-2 minutes) after starting them. This could be a problem during software updates, because the locked (still open) exe files can not be replaced.

    this is really happening in windows 7: http://superuser.com/questions/260375/why-would-system-continue-locking-executable-file-handles-after-the-app-has-exit

    And is it possible to delete the “Paul” comment from 2013.
    What he said is, for this service, is just wrong and does technically make no sense.

  5. Paul3 says:

    Paul2 is right that it CAN cause problems but it depends on your hardware, whether it is new or old. Paul is also right, Microsoft couldnt organise a drink in a brewery at the best of times, so shut up Paul2!
