Ask HN: Why can't Windows safely restore faulty .sys files from backup on boot?
2 points by Beardy 11 months ago | 2 comments(1) Keep backup of all .sys files on healthy boot, (2) When bluescreen, log for recovery on next boot, (3) At recovery boot, load each .sys, (3a) If healthy, log it into safe batch, (3b) If bluescreen, mark it as unhealthy on next boot, (4) Continue until you have a list of healthy and unhealthy .sys, (5) Restore unhealthy from backup, (6) Disable automatic updates for unhealthy .sys, (7) Log alert for system administrator
Is there any reason this isn't something that's implemented? I really am just curious and would love your thoughts, as I do find this area very interesting.
Thanks!
- Someone 11 months agoWindows has “system restore points” to which you can roll back. Those can help in rolling back a driver update.
In this case, however, the .sys files aren’t drivers, just config files that have a .sys extension, so such a recovery mechanism would have to be part of CrowdStrike, not Windows.
