WM_NAME = "Windows Messenger"
WM_TIP = "Adds or removes access to Windows Messenger from the Start menu."

If that doesn't fix it there's a couple of other options you can try.

Go to Start > Run and type in sfc /scannow and hit enter.(leave a space between sfc and / ).That will revert some of the files back to original XP ones,and then you will have to run the SP2 RC1 install again.

or

Upgrade to SP2 RC2 to see if that corrects the problem.
