already downloaded update is there a easy way uninstall or clear it?

I have a update downloaded.
It trys shut down install and it frezzes, or crashes, or breaks windows.

All my restores seem to contain some update. No matter what fix I run, what program I run nothing can fix the problem

The update is already installed, I can no longer Update windows because its waiting to shut down and install this one (when I try that it fails)

This is possibly root cause of most my issues with windows. Though ask about this because im worries I might keep having this problem. I have read a lot about people having update issues with windows 7 so any info be great thanks,

BTW its already downloaded its not installed, if try install won't go through. If I try fix it doesn't work I need a way to just.... get rid of it all together.

I dunno let me know. Seems be common issue be nice know the sollution

* It would be helpful to have more information re your System specs.
Please refer to the following Tutorial.

System Info - See Your System Specs

* Can you tell us the KB number of the troublesome update?
Any Error messages associated with it?

* Have you checked in Event Viewer?
Type eventvwr in search.
Go to the Windows Logs > Application / System > in the left hand column.
Note anything in red that relates to the current problem only!
Please record the event ID, and the Source Code and tell us what they are.
