A lot of problems arise from setting Windows Update to automatically update. You may prefer to change this setting. Select Start, All Programs, Windows Update, Change Settings. Under Important Updates is a box showing the current setting. Click on the Arrow down to the right and change the selection to “Check for Updates but let me choose whether to download and install them” and click on OK.
You could also download and run the System Update Readiness Tool from this [LINK] and choosing your version of Windows.
