Thanks . I was just thinking I might try rolling back . I have a Windows 7 Dell with Corei3 processor . I haven’t updated this PC yet as I feared a similar problem . I left the computer on all night so I’d have at least one working . Are you saying that the patch won’t cause the Dell any problems ? I’ve turned off updates until I get def. info .
Supposedly the patch only affects some non-Intel processors, BUT, given your situation and my innate caution, I’d recommend you try rolling back the one that’s already unusable before updating the one that still works. Then, if you can get the first one working again, you should be okay to update the Intel-based one.
