Windows 7 SP1 64bit Install and Uninstall problems
I installed Windows 7 64bit SP1 a few weeks ago and it never completed the installation, so when I reboot the computer it constantly returns to Stage 4 of the set up and then fails at 69%. The computer then proceeds to reboot, but runs very slowly, and glitches occur when running various programs. It also continually tries to install security update KB2556532, but this install, which says it has been completed successfully, fails every time (and the system has tried to install this fix more than fifteen times). To solve the problems I tried to uninstall the Service Pack through Control Panel (programs and features utility), but when I bring up that screen it says that there are NO installed updates, even though I know for a fact that there are dozens of them.
Can I use the Windows 7 disks to do a repair, or do I need to do a clean install?
