Fix Windows slow shutdown problem with UPHClean

Recently, I found my Windows PC became extremely slow for the shutdown process. It used to shutdown without 30 seconds, but then it took as much as 5 minutes.

A check in the Application Event Log found 2 warnings whenever I shutdown the PC. They are:

  • Windows cannot unload your classes registry file - it is still in use by other applications or services. The file will be unloaded when it is no longer in use.
  • Windows saved user PCname\username registry while an application or service was still using the registry during log off. The memory used by the user's registry has not been freed. The registry will be unloaded when it is no longer in use.
I'm not sure why this happened, but I've found out a solution from Microsoft to fix it. Microsoft released the User Profile Hive Cleanup Service (UPHClean) to resolve this problem, and it did solve my problem.
