Default Behavior

Application Experience is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the Application Experience service is started, it is running as localSystem in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Application Experience fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the AeLookupSvc service is not running because of the error.

Restore Default Startup Configuration for Application Experience

1. Select your Windows 7 edition and service pack, and then click Download.

2. Save the Win7_AeLookupSvc_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The AeLookupSvc service is using the aelupsvc.dll file that is located in the %WinDir%\System32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
