For some reason Microsoft did not deliver February 2017 updates for Windows 10. Speculation has been all over the dial. Contrary to other sources, this is not exclusively an update for insider test builds.

Is the last update in the catalog, and installing it will reboot your machine. This update is cumulative and it has all the components needed for anniversary build 1607.

Windows 10 version 1607 build 14393.726 will be shown after this update. Open settings -> about.

Manual install has been available for all updates in the catalog and this is the latest cumulative update that should have been delivered with February’s updates.

The Malicious Software Removal Tool is also available.

Office updates are not affected, the problem seems to be for Windows 7, 8 and 10. We have long standardized on Windows 10 which is the best platform for gaming.
