I've tried to install the SP1 pack from the Windows Update site, but I keep getting these messages (see attatchment) I have all other programs closed including any antivirus software. I also have Crytography enabled. Oh, and I'm also running a legit copy of XP Home. In other Update News, when I go to d/l the IE 6 SP1, I get messages about the download not being Windows Compatible (something about Windows logo). However, I dont care much about the IE SP because I know it is included in the XP SP. Just curious as to why this message is popping up. Could it be that MS doesnt trust its own software?
