This is very much a “easier said than done” situation that I would think Hacker News of all places would be better about when it comes to “just” doing something in code. First Windows already does something similar. After 3 it is supposed to boot into WindowsRE which gives you options to revert to a previous version, uninstall updates, and I believe also reverts configurations like recent driver installations. The problem here though, CrowdStrike itself didn’t update. It updated a definition file (last I saw at least) and that likely would not have been caught by Windows as a new version. Also frankly, not super thrilled at the idea of Windows just deciding to disable/uninstall something except for rolling back (so a previously working config) due to how things could interact. This situation could have been far worse and harder to recover from. In this case maybe Windows could have noticed that the configuration update is what was causing it and rolled that back, but it’s possible it would have just re-downloaded the file when it started back up anyways. Regarding saved lives, do we actually know that anyone’s lives were lost due to this? My local hospitals were still performing emergency surgery.
