Update — Revert Windows
Microsoft treats your OS like a transactional system. Patch Tuesday applies a delta. If the delta is corrupt, you cannot simply subtract it. You have to hope the next delta overwrites the corruption.
Why? Because you lose agency. You are no longer deciding to revert; Microsoft is deciding to un-brick you on their timeline. If a patch breaks your obscure RAID controller or your legacy audio interface, you aren't waiting for a new patch. You are waiting for Microsoft to admit the patch was bad and push the KIR.
We’ve all been there.
It sounds magical. It is terrifying.
The culprit is usually an antivirus, a locked system file, or—ironically—a previous update that corrupted the Volume Shadow Copy service. If you want to revert a Windows update today, you have to abandon the GUI. It is a trap. Open PowerShell or CMD as Administrator. Run this: revert windows update
In practice, System Restore fails silently. You’ll wait 20 minutes, only to see: "System Restore did not complete successfully. Your computer's system files and settings were not changed."
It’s Tuesday morning. You hit “Update and Shut down” the night before, thinking you’re being responsible. You wake up, brew your coffee, log in, and... your secondary monitor is a strobe light. The context menu takes four seconds to render. Or worse—the dreaded “We can’t sign you in with this credential because your domain isn’t available” error, despite sitting three feet from the router.

Keep your recovery media handy. Memorize wusa /uninstall . And never— ever —run Disk Cleanup within two weeks of Patch Tuesday.
