What exactly did you update? Hardware? Software?
If hardware then I don't think it is caused by this update. In this case you probably want to remember if and what settings have you changed in IE or anything else. I have had ridiculous problems with really simple solution, yet I mess with them whole day thinking it must be something new I have installed, just because I forget that I changed some minor settings or disabled some services.
If you updated some software, like IE, Windows, Java.. anything. Then there is always chance (A BIG one!) that even the biggest, best funded companies let some buggy sh*t out. It might be that new update doesn't suddenly support some of your hardware or something like that.
In this case you probably might want to restore your system to earlier stage, and hope that they have fixed the problem in next update.
Or if you have Java installed for a long time try to install new one, if you have the new version, then re-install it. If that doesn't help re-install IE, if that doesn't help then try out FireFox.. you will never want to see IE again
Also, there is SUN Java and Micro$oft Java. If you are using SUN java then try out M$ one, or vice versa.
