1. look in your add-remove programs and check the box that says "show updates". See which updates match the day you updated your computer and try to uninstall them.
2. you can look in your startup menu and see which programs are in there. it might not be caused by this update. Run>msconfig, hit enter. Go to the Startup tab and see which programs are there. Are there any that you don't recognize, or want to start up?
Some cleaning programs such as ccleaner can remove the "hotfix uninstallers" which are needed if you want to uninstall an update. Hopefully you haven't done this.
On 13 February 2008 I received two new security updates from Microsoft for my Windows XP Home edition. Since then my 2.4 Ghz machine takes between 5 to 10 minutes to boot. As much as 15 before I dare to get on the internet.
System will not let me restore settings now.
And my IE 7.0 is slow and checks for certificates since 8 Mar 2008.
