Supportability for SharePoint 2010 SP2 and Windows Server 2012 R2

Before the release of Service Pack 2 (SP2) for Microsoft SharePoint Server 2010, Microsoft did not support SharePoint Server 2010 in a Windows Server 2012 or Windows Server 2012 R2 environment.
However, SharePoint Server 2010 with SP2 has now been released, and this configuration is supported in Windows Server 2012 and Windows Server 2012 R2.

As of May 1^st, 2014, deployments from the slipstream media available on VLSC and MSDN we only support Setup of SharePoint 2010 SP2 slipstream media (not RTM + SP2) on Windows Server 2012 R2. For this to work, the 2014 Feb CU (or newer) is required.

Please note that only fresh installing of SP2 slipstream + Feb CU (or newer) on Windows Server 2012 R2 is supported.

We don’t support OS in-place upgrade.
