Default Behavior

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

Dependencies

Certificate Propagation can't start, if the Remote Procedure Call (RPC) service is disabled or not available.

Restore Default Startup Configuration for Certificate Propagation

1. Select your Windows 8 edition and update pack, and then click Download.

2. Save the Win8_CertPropSvc_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

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