Do not roll back a security update that patches a critical vulnerability being actively exploited (a "zero-day"), unless the update itself is causing worse damage (e.g., preventing boot). In corporate environments, consult IT first.

After restarting, Windows may attempt to reinstall the same update automatically. To prevent this temporarily, use the "Pause updates" feature in Windows Update settings for 7 days (or up to 5 weeks on some editions).

This works even if you cannot log into Windows.
