Default Behavior

Interactive Services Detection shows message boxes when it is necessary. In Windows 7 it won't be started if the user doesn't start it. If Interactive Services Detection 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 UI0Detect service is not running because of the error.

2. Save the Win7_UI0Detect_Service_Startup.cmd file to a local storage device.

The UI0Detect service is using the UI0Detect.exe 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.
