Has anyone had a chance to roll the latest update from Microsoft to Exchange 2010 SP1, the rollup is Rollup 8. I started the install through Windows Update, and its been sitting on it for over 2 hours now. Is this normal? Rollup 7 only took about 35-40 minutes to install when it got released. Any suggestions on what I should do? Should I let it keep going, or cancel the Windows Update process, reboot the server, and try it again?
