SP1 failed to install
I am running Win7 Ultimate 64-bit with all previous updates installed. I also have XP mode installed on my virtual machine. I tried to install Windows 7 Service Pack 1 for x64-based Systems (KB976932) today via Windows Update. The download took over 2 hours with my high speed cable internet. The install took about 2 hours after the download. When the install finished, it prompted me to reboot. After rebooting there was a "file loading screen" before the normal windows loading screen. I received a "Fatal error C000009A applying update operation 119978 of 338264 (\Reg...)".
After several attempts i was finally able to revert back to a previous system restore point. Why is SP1 failing to install for so many people? Should I perform a clean install of Windows 7 first before installing SP1? Or should i not install SP1 at all until these problems are fixed?
