After installing SP2 on my Dell machine I started getting User Event ID: 1517 indicating that I had a User Hive Closure problem. After a LOT of research I found a tool made by Robin Caron who is a software writer for MS. She made a program called "UPHClean" that closes all Handles that programs etc. leave open after the program is done being used. This is a good thing because I was quite concerned about this issue when I didn't have any way to fix it. The reason for my post is to alert anybody that is using the Home Edition and has SP2 loaded that they should check Applications in Event Viewer to see if you're getting this warning message. If so, I strongly recommend downloading this tool. I'm sorry that I didn't keep the web site address for it, but it is at MS's site. If anybody else is having this issue would you please post that you are. A MS MVP Brody Mulry wrote an article about this very issue and commented that he personally found 34 machines doing this. Please let me know if you would.
