@MarvinFreeman @Ash_Crow @HugeGameArtGD @szbalint @hanno It's not by any means deployed everywhere with WIndows. They have almost no market impact in the consumer space, for example, which is why millions of people turned on their home Windows machines today and had no problems at all.

But in the business world, there are only a few companies offering that sort of product. So let's say they have a (guessing) 10% market share -- that means 10% of businesses will be hit by the problem. That's a lot of high-visibility outages.
