Remove Hyper-V role restart hangs at 76%

Postby stephen » Fri May 14, 2010 8:19 pm

I removed the Hyper-V role and rebooted. The system to get to "Configuring Updates : Stage 3 of 3" then hang at 76%! My system was an IBM System X SBS 2008 std server. I had enabled the Hyper-V role, then found out later that Hyper-V is not supported on SBS Server 2008. So I removed the role and clicked restart when requested. After 12 hours the server was just at stage 3 of 3 of the Configuring Updates with the 76% mark.

I found a solution here which worked

Rename pending.xml in System Recovery options

----------------------------------------------------------------------

When an update is installed, some operations need to be performed when the computer is restarted. These operations are recorded in the pending.xml file. If this problem continues, we may perform the following steps to rename the pending.xml file and delete the corresponding registry key to let the system bypass remaining update operation. You will be able to logon to the system again. However, please note that after this operation is performed the update may not be installed properly and certain Windows features may not function properly. It is recommended that you backup your data and reinstall Windows.



1. Insert the Windows Server installation disc in the disc drive, and then restart the computer.
2. When you are prompted to restart from the disc, press any key.
3. When you are prompted, configure the Language to install, Time and currency format , and Keyboard or input method options that you want, and then click Next .
4. On the Install Windows page, click Repair your computer .
