Hello, I have had the above security update for IE8 install through Windows Update. Has anyone else had issues? If I shut down the system, when rebooting, I get an error message " Cannot access Userfile: may be not on this disk". I am able to get around this by logging off as the current blank user. The system also has gone to Classic View with no option to change to the Vista view. The sidebar is also now opaque instead of transparent. I have a Compaq laptop with 32 bit Windows Vista Home Premium, Mobile Sempron processor 3500+ 1.8ghz with 1gb ram.
