Thanks for posting here in Microsoft Community.
Kindly answer the following questions below:
- Was the PC left fully powered ON (not restarted, not sleeping) for a full 2–3 hours?
- Did the screen ever go black, sleep, or get shut down during the wait?
- Did anyone try entering the PIN again during the waiting period?
- Is this a personal PC, or was it set up by a school, workplace, or repair shop?
- Has the Microsoft account ever been recovered or reset before?
- Was the account originally set up with a PIN only, or was a password used before?
Thank you! Hoping to hear from you soon.
