OS: Windows 11
Account Type: Microsoft Account
The Situation / How it happened:
A friend entered the wrong PIN too many times on the lock screen, locking the laptop. We rebooted the machine and successfully bypassed the lock by using the owner's registered fingerprint.
Once on the desktop, we immediately went to Settings > Accounts > Sign-in Options and clicked "I forgot my PIN" to reset it.
Note: While doing this, the Microsoft Account verification modal kept spontaneously closing itself like it was on a timer or crashing. We rushed through it, managed to input the single-use email code, created the new PIN, and confirmed it.
To test it, we put the laptop to sleep and woke it back up. We are now completely locked out.
Current Symptoms:
Lock screen displays: "Something happened and your PIN isn't available. Click to set up your PIN again."
Clicking the "Set up my PIN" link does absolutely nothing.
Fingerprint scanner is now disabled because Windows requires a PIN after sleep/reboot.
__The owner forgot the laptop Password (Key icon).
Shift + Restart:__ (Using both the physical keyboard and On-Screen Keyboard). The laptop ignores the command and reboots normally to the lock screen.
3x Hard Power Crash: The laptop shows "Preparing Automatic Repair" under the OEM logo, but it completely bypasses the blue Advanced Options recovery menu and drops us straight back to the broken lock screen.
