November 2015 update I had an automatic Vista security update downloaded 11/12/15 . My PC now shuts down every time during startup process, with error message re BlueScreen. I have tried ( in SAFE mode ) going to control panel to uninstall the recent updates, but get a message that uninstall was not successful. I cannot access internet while in SAFE mode, so have not been able to download anything to fix the problem. Unsuccessful with any " in PC diagnostics or fixes. Any suggestions would be appreciated.
