Terminal Server 2003 msiexec high cpu usage, hp upd

Ok, so this has been killing me for a while. I have a terminal server that was unable to add/remove applications in a timely manor; when I say timely, I mean TIMELY! It could take days to install Office, or HOURS to install a security patch.

I still haven't fully isolated what causes the problem to start (possibly bad printer driver). But this solution worked for me this time.

I removed these Registry Keys; which were full of HP garbage.
[HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal Server\Install\RefHive\Hewlett-Packard]

I then made sure that there were no Universal Print monitors.



  1. Have to say that this has helped me greatly. Had a massive problem with a Terminal Server for the past 3 years - migrated to VMWare tonight and nothing would install - finally had to face up to fixing this problem. Without your post I'd still be trying to throw the kitchen sink at it. Credit goes to you!
