Default Behavior

DialogBlockingService is a Win32 service. In Windows 10 it is disabled. When the DialogBlockingService is started, it is running as LocalSystem in a shared process of svchost.exe along with other services. If DialogBlockingService fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the DialogBlockingService service has failed to start due to the error.

Restore Default Startup Configuration for DialogBlockingService

1. Run the Command Prompt as an administrator.

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

sc stop DialogBlockingService
sc config DialogBlockingService start= disabled

3. Close the command window and restart the computer.

The DialogBlockingService service is using the DialogBlockingService.dll 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.
