I would just leave it alone. If Sp2 is installed then you are good to go. Cross other bridges when you get to them.
My computer has Windows XP. In one of those pop-ups from Microsoft telling me that updates were ready for my computer, offering me SP2, I accidentally clicked OK, and couldn't stop the download! I was under the impression that there is a substantial amount of preparation for SP2, and hadn't done any of that (not intending to download it at that time). In an effort to get rid of SP2, I did a "system recovery" to a few days prior, but that only messed up my Norton anti-virus program, so I undid the recovery. So far, I don't see any problems with SP2, but am "waiting for the other shoe to drop". What should I anticipate? Should I try to remove SP2? How? Many thanks for your time & attention.
