Answers :

If you have restore turned on your system should have made a restore point before installing the update. Try and roll it back to before the install, Go to accessories, system tools, system restore. It should show the install of the update that created the problem, restore it to that point. check and see what the update was for and if you need it, if not block it from updating that one again on the update page.
Go to control panel, open add remove software, then uninstall the updates you have installed yesterday which you think caused the problem. restart
