Why the fuck didn't MSFT just do blue/green canarying? No update should be rolled out to a billion devices at once until it's baked in a million devices for a bit, and that only after baking in 10,000 devices for a bit.
Crowdstrike broke the update for Windows only this time. Although look around, they did a bad update on Linux earlier this year (although that only broke some of the Linux installs).
