I'm running Windows 7 64-bit within Parallels 11 for Mac and am running a Windows Update at the moment and there has been no change in progress now for over 20 minutes. I'm in the process of downloading 9 updates. This is the case every time I've tried updating, eventually it works but it takes forever. I have 2 out of 4 cores allocated and 4GB of RAM out of 8GB or RAM, if that makes any difference. Thanks everyone.
