New VM's running Server 2012 Standard OS are extremely painful to run MS updates on. Some patches take forever to install, even the smallest ones. I have one 100 KB update that has been stuck on 45% now for 20 minutes. Other OS's like Server 2008 R2 and even our old Server 2003 servers update in a flash - both VM's and physical. I have to kill updated and run them over and over one update at a time on these servers in order to patch them. Any idea's on how to correct this issue? I even blew away one VM before going live and build it again, same issue. Created Server 2008 R2 VM and tested, no issues.
