As expected before the RTM release SCCM 2012 R2, ConfigMgr 2012 SP1 CU3 has been released. SP1 CU3 adds support for Windows 8.1-based client for the following features 1) Software distribution 2) Software update management 3) Compliance Settings. SCCM 2012 SP1 CU3 also includes loads of bug fixes as well. CM12 SP1 CU3 update replaces Sccm SP1 CU2, so if you’ve not already applied CU2 then go ahead and install CU3. No need to install Cu2 and the CU3.
