Default Behavior

Interactive Services Detection shows message boxes when it is necessary. In Windows 10 it is starting only if the user, an application or another service starts it. If Interactive Services Detection fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the UI0Detect service has failed to start due to the error.

Restore Default Startup Configuration for Interactive Services Detection

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

3. Close the command window and restart the computer.

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 10 installation media.
