I run Win7 on a Boot Camp partition on a 2009 MacBook Pro. For a couple of weeks, Windows Update has refused to work. Last night, for example, I launched WU and watched the progress meter move v-e-r-y s-l-o-w-l-y for about an hour. It never produced a list of pending updates. I ran the Update Troubleshooter, but no joy. As far as I could tell, the troubleshooter did nothing at all. My update history shows several items that failed to install, including an update to the Malicious Software Removal Tool.
Suggestions, anyone?
