I have been getting messages from Windows Update that I should install the Windows XP Service Pack 3 (SP3) on my PC. When I tried to install it from the SP3 CD, I got a message that it couldn’t be loaded because a previous fix – KB925877 – needed to be removed. Straightforward? But when I tried to uninstall that KB, the system listed a very long list of programs that would be affected. So I have abandoned XP SP3 for a while.
