Because I'm a glutton for punishment, I recently started rolling out System Center Configuration Manager 2012 R2 SP1 and System Center Endpoint Protection across our VDI environment. There are always some considerations to be made in a pooled desktop / gold image type environment when loading software that uniquely identifies devices, but lucky for me SCCM/SCEP handled this just fine without any tweaking. However, there were some nuances to how SCEP policies are applied that caused some serious hair-pulling before I spotted the issues.
