Running Windows Media Player 10 on Windows XP Service Pack 2
I came across this problem while I was beta testing the XP SP2 release candidates. Every build starting with RC2 and later would not let me reinstall WMP10. It was very frustrating. Well, tonight I came across a solution in the WMP10 Beta Newsgroups. It involves removing specific keys from the registry. The problem is, those keys may vary by name, so a simple registry script will not work. So I whipped up a simple command-line program that will cycle through the proper Registry key, and delete all its subkeys.
PLEASE NOTE: This problem only exists for Windows XP Service Pack 2 - Build 2142 and later. Running this program on the Service Pack 2 RTM without having installed previous builds should not cause a problem. That being said, there are no warranties, express or implied, associated with this utility. It is provided as-is. Use at your own risk.
Enjoy.
