Installing Windows Updates on Server 2012 Standard VM

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.

Windows Updates can take a while to install depending upon how fast your datastore is.

So what is the datastore?

e.g. RAID, Disk type SATA or SAS, 7200, 10,000, 15,000 rpm.

We have a Nimble SAN with SAS drives. All VM's use this SAN datastore and only the 2012's VM's have any issue with Windows update.

Out of all our VMs, Windows 2012 updates are the slowest, but not unusable.

No it works, it's just a slow process and didn't seem normal to me. But perhaps for Windows Server 2012, it's normal. Thanks.

We usually create and patch a Golden Master, and role this out as a template, and patch once a month.
