Of course, of course. This is how these things are always done.

I like how they kept on pushing the update for hours

And who pushes out production updates on a Friday!

Code review, QA team, hours of being baked on an internal test network, incremental exponential roll out to the world, starting slow so that any problems can be immediately rolled back. If they didn’t have those basics, they have no business being a tech company, let alone a security company who puts out windows drivers.
