First of all I caution all of you that are not computer experts to proceed at your own risk. It appears Microsoft is reporting that if you have Service Pack 2 Release Candidate 2 installed you can merrily surf along with Internet Explorer.
Bur the 2nd service pack for Windows XP is just that a release candidate still under test and while it probably would not break your installation of windows it could screw up a some of your programs. Companies that are affected by changes to XP from the service pack are rushing to update their products so that they can be ready when Microsoft releases the Service Pack for the average user.

Thanks to John for the heads up!
