Default Behavior

Application Information is a Win32 service. In Windows 8 it will not be started until the user starts it. When the Application Information service is started, it runs as LocalSystem in a process of svchost.exe, sharing it with other services. If Application Information 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 Appinfo service hasn't been started.

Dependencies

Application Information can't start, if any service from the list below is disabled or not available:

The Appinfo service is using the appinfo.dll file that is located in the %WinDir%\System32 folder. If the file is corrupted or deleted, you can put it back in there.
