It gets worse if your machines have bitlocker active, lots of typing required. And it gets even worse if your servers that store the bitlocker keys also have bitlocker active and are also held captive by crowstrike lol

I've already seen a few posts mentioning people running into worst-case issues like that. I wonder how many organizations are going to not be able to recover some or all of their existing systems.

Presumably at some point they'll be back to a state where they can boot to a network image, but that's going to be well down the pyramid of recovery. This is basically a "rebuild the world from scratch" exercise. I imagine even the out of band management services at e.g. Azure are running Windows and thus Crowdstrike.
