Default Behavior

Application Experience is a Win32 service. In Windows 8 it will not be started until the user starts it. When the Application Experience service is started, it runs as localSystem in a process of svchost.exe, sharing it with other services. If Application Experience fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the AeLookupSvc service hasn't been started.

Restore Default Startup Configuration for Application Experience

1. Select your Windows 8 edition and update pack, and then click Download.

2. Save the Win8_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 corrupted or deleted, you can put it back in there.
