XP SP3 RC2
For anyone interested. Two days ago I installed XP SP3 RC2. This if the final RC before public release. I have found it to be very stable and have noticed no performance degradation. Actually I have found no major changes yet. I did have to restart twice to get the installation to finish properly.
Please, for anyone wanting to upgrade to SP3 RC2, or the final release for that matter be advised that any previous SP3 release installation must be removed before installation. In some cases Windows XP SP3 Release Candidate 2.exe script must be run before installation to remove a Kb that could interfere with installation.
One other item that might be of interest to those of you who use TGT StyleXP on other machines to check out msstyles. SP3 will break your installation and you will not be able to use it, as TGT has no update available to use with this version of Windows.
