I was trying to create a Windows 2012 Template for SCVMM 2012 R2. As the normal process I follow, Started a full Windows update just after the OS installation.
~75 updates was present including optional updates. The first attempt failed and it took few minutes to revert the changes and get the server rebooted.
The next attempt was to go for a partial update. First, I only opted optional update which went successful and server got rebooted.
The second attempt was to take half of the updates which was even successful.
The third attempt was to use the entire pending list which again failed. Suspecting one of the update in the list is having some trouble.
Investigating more and update here if I find some issues.
Please check my latest post for update on this issue.
