I have a hyper-V environment running 20 - 30 virtual machines on each host hyper-V server. All Host servers are running Windows 2008 r2. I am in the process of migrating VMs off each server and running windows updates and moving them back. After successfully upgrading to Sp1, I install further updates then reboot the Server when prompted. The server starts to shut down and I get this message "Failure Configuring updates Reverting Changes Dot Not turn off computer. It then restarts. Then displays the same message and restarts again. The whole process takes 2 3 hours. Also, after this event every time I RDP into the host it hangs on the welcome message for 5 - 10 minutes before I can access the desktop. We are using Data Protection Manager to back up my VMs and I have found the following post with a similar issue: However I do not have a mass of registry entries in the following registry folder, like they seem to have HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\STORAGE\VolumeSnapshot Looking through the event log I have found the following Windows update error code 0x800708 with the following windows updates. Some appear more than once.

I have experienced this with 3 servers so far. These upgrades are part of a larger upgrade of our Datacentre infrastructure which we cannot continue with until this issue is resolved. Regards Jason
