XP Activating and Update problem

I integrated the Service Pack 3 to a Windows XP with SP2, but problems
occured when I was logging, sometimes when I started the PC and typed the
password on the Welcome screen, it says that "A problem has prevented the
activating...error code xxxxx", I forgot the details. So I must reboot the
computer then F8 to boot the Safe Mode, then reboot the computer again to
normal mode, that message disappears.What is this???
And there's another problem. I attempt to install the Cumulative Security
Update for IE7(KB950759), it says successfully installed in the automatic
updates, but when I reboot the machine, it prompts this again, I download the
KB950759 and tried to install it manually, but the problem was the same, I've
shut down the firewall, but the problem is still there, so please help me.
Thanks!

Updates are not installed successfully from Windows Update, from Microsoft
Update, or by using Automatic Updates after you repair a Windows XP
installation:
