I recently installed a couple Windows updates, some of them optionals. One of them made my music files playback sound weird with some kind of breakoffs when using Windows Media Player. The other one made my Microsoft mouse behave in a erratic way by slowing down the pointer when being moved around my monitor screen. Then, I decided to uninstall the Windows updates that I am referring to. I first went to the Add/Remove Programs to see if they were displayed there. But they weren't. I couldn't see them even when clicking on the "View Installed Updates"button. Then, I tried to launch System Restore, but my machine is not keeping restore points whatsoever. Upon finishing System Restore activity, I got the error # 0x80070005, which I tried to solve by doing a search for a solution right here in the Expert-Exchange site. I could NOT find a solution.
Could you tell me what I should do to find these "hidden updates" so that I uninstall them..not to say to really get RID of them?
