You can’t keep a good idea down.

Late last week, Microsoft released a Windows 10 version 1607 preliminary cumulative update via a new channel. As I explained in , a preview of the cumulative update was made available only through the Windows Update Catalog. That way, people who wanted to test the fixes could download it manually, but regular Windows users wouldn’t be hit with an unexpected (and potentially not-fully-baked) patch.

Well, Microsoft has done it again.

Yesterday, Windows Server 2016 users got a new cumulative update, KB 4010672, which brings the build number up to 14393.729. It’s a very specific hotfix, aimed at Azure VMs losing network connectivity, that’s on the Win10 changelog site. The hotfix doesn’t come down the automatic update chute; it’s only available and manual installation.
