Today Microsoft pushed out a cumulative update to Windows 10, without saying what has been changed. Given that it's a 30 second download and two-minute install there probably isn't much in it at all.
What there is, however, is a demonstration of Microsoft's intention to keep rolling out updates on a timely basis.
That represents a good start to Windows as a Service.
Leaving just two things for Microsoft to sort out. The first being a change list, to confirm what has been fixed. And the second is to make sure the updates get folded back Me to the main Window back into the main Windows install, 50 that users getting their updates aren't being asked to install updates immediately they complete their upgrade.
