Hi, my Windows 7 updated approximately a week ago (despite me selecting DO NOT install updates - it still sneakily installed an update when I was shutting the PC down, as it comes up in a tiny bubble when clicking the shut down icon "shut down and install updates". I'd already pressed shut down by this point, so it went ahead and installed)...

Ever since the update was installed the PC has been running a lot slower, and when I put a USB stick in or HDD the PC will lock up for approx. 1 minute, then it'll have the egg timer, then the screen goes black and I have to manually power the PC off. This then means I have to go through 30 minutes or so of startup repair before I can log on again.

My questions therefore are;
1) Does anybody know how to fix this so that USB storage devices don't cause the PC to go into meltdown? (I've tried all the USB ports and get the same result).
2) How can I uninstall the recent update?

thanks

Hi dodohelp. To check your update history go to Start< Control Panel< System and Security< Windows Update< click on View Installed updates and sort them by date installed. Then you should be able to uninstall the update from there.

Does the USB black screen issue happen if you boot the computer in Safe Mode?

Thanks. I'll try the uninstall and see if that works.

I haven't tried it in safe mode. How do I boot in safe mode? Do I press an F button when turning the PC on?

USB sticks/ HDDs work fine in safe mode but cause the PC to lock up n normal mode. This is driving me crazy. Why is it doing this!!!!

by the way this filepath doesn't exist on windows 7 so I have been unable to uninstall the windows updates

Start< Control Panel< System and Security< Windows Update< click on View Installed updates

I only have "system" and there's nothing in there about windows updates

This would normally suggest that it was an issue with a third party driver.

Have you checked for a system restore point that is before the time and date that the issue first became apparent.

Tip
If using a computer and not a mobile phone, please avoid adding multiple posts while waiting for us to reply to your OP or last reply, edit your last/opening post to include anything that you wish to add, when viewing the boards members/staff will always check out an OP that has no replies, if you reply to your own OP it can appear to others that you are already being assisted and your request for help could be overlooked, something that none of us want.
