Having left Windows Update running for a day and a night - over 24 hours - it still displays "Checking for updates..." with the progress bar happily drifting from left to right. I was advised (elsewhere to:Disconnect from internetRestart PCManually run 1st install (KB3102810)Restart PCRun 2nd install (System update readiness tool)Restart PCConnect to internetCheck for Windows UpdatesDone!Sadly this didn't work, I followed the instructions to the letter and saw the following result: 3a) Windows Update Standalone Installer - KB3102810-x64 - 3,251 KB.Runs continuously saying "Searching for updates on this computer". A MsgBox pops up after a while saying "The update is not applicable to your computer". KB3102810 continues to run. When you click [OK] on the MsgBox, KB3102810 terminates. 5a) System Update Readiness Tool - KB947821-v34-x64 - 551,509 KB. Also called "Windows Update Standalone Installer"?Runs saying "Searching for updates on this computer". A MsgBox pops up asking "Do you want to install the following Windows Software update? Hotfix for Windows (KB947821)". When you click [Yes] it runs displaying "Copying packages to the Windows cache" and then changes to a new MsgBox saying "The updates are being installed". It attempts to install Hotix for Windows (KB 948721) (update 1 of 1). This never actually completes, it moves quite rapidly to within about 1cm of the end of the progress bar but never gets beyond this point. Looking at the Event Log, Error 7034 ("The Windows Modules Installer service terminated unexpectedly") clocks up every 30 seconds. Also . . . every time I boot the computer it appears to attempt to install updates and then fails and reports that it is reverting changes. Needless to say this means that booting the thing takes ages! I know that this appears to be a recurrent issue with Windows 7 but perhaps the level of detail I can provide will help? Can anyone help PLEASE?
