I want to uninstall SP3 because I think it might be preventing one of my vital Canon camera applications from loading or installing. I tried to uninstall SP3 via Control Panel and the Software Update Removal Starts and a message pops up which just says "The System can not find the File Specified" then "Service Pack 3 was not uninstalled". How can I remove SP3? All of my applications worked with SP2.

I think I installed SP3 5-7 mths ago so I do not want to restore my PC way back to that time just to delete SP3.

Right from Microsoft.

I tried all these options before and they are basically the same as using Control Panel and did not work.

Then a Restore point will be your only option. If you tried everything that Microsoft has suggested then a restore to a point before you installed SP3 will be the only thing that can be done.
