Updates Microsoft upates released on 6/14/2011 are giving me issues on Windows 7 x64 machines. After rebooting, the Windows logo appears then the screen goes black and just sits there. I've lauched startup repair and it doesn't work. I've had to do a system restore and now several snapins will not work such as the event viewer and network diagnostics. I'm currently running sfc /scannow however it has been stuck at 13% for the last 45 minutes. Any help?
