The Application Experience (AELookupSvc) service is a part of the Application Compatibility Administrator. It processes application compatibility lookup requests for applications as they start, provides support for computers that are running programs in compatibility mode, reports on compatibility issues, and automatically applies software updates to programs.

The Application Experience service must be active for application compatibility software updates to be applied. You cannot customize this service; the operating system uses it internally. This service does not use any network, Internet, or Active Directory Domain Services (AD DS) resources.

If you disable the Application Experience service, the service continues to run, but no calls are made to the service. You cannot stop the actual process.

This service is installed by default and its startup type is Manual. When the Application Experience service is started in its default configuration, it logs on by using the Local System account.

This service is not dependent on any other system service, nor is any service dependent on it.
