Microsoft has released a February update rollup for Windows Server 2012 R2, as well as Windows 8.1 and Windows 8.1 RT. This is a much bigger UR than the one that was just released for Windows Server 2012.

I’ve noticed two updates that Hyper-V and/or clustering folks should be aware of:

KB2920469 deals with a situation where you cannot change the schedule for CAU self-updating mode in Windows Server 2012 or Windows Server 2012 R2 by using CAU GUI.

Assume that you have a cluster that runs Windows Server 2012 or Windows Server 2012 R2. When you try to change the Cluster-Aware Updating (CAU) schedule by using the GUI, the time for the automatic update schedule is not changed, and the old time remains.

KB2920196 is for when you cannot create or change the name of a debugger named pipe for a VM when it is running in Windows 8.1 or Windows Server 2012 R2.

When you have a virtual machine that is running in Windows 8.1 or Windows Server 2012 R2, you cannot create or change a debugger named pipe’s name for the virtual machine while it is running.

This issue occurs because of a regression that is introduced in Windows 8.1.

As I said in the WS2012 post, don’t be an IT haemophiliac; delay approval of this update for a month and let the rest of the world be Microsoft’s test lab. If you don’t see any update to this update in one month, then approve and deploy it if you’re happy.
