Hello, thank you for reaching out to Microsoft Q&A.
May I please know if you have the option to reset your PIN from the Windows Hello Sign-in Screen?
Select the 'I forgot my PIN' option on the Sign-in screen, and follow the prompts to reset your PIN.
For reference, see
How to reset your PIN if you aren't signed in
If you are having trouble resetting your PIN, try booting your PC in safe mode, where you can use your password to sign in. Then, you can reset your PIN from there.
To boot your PC in safe mode -
- Turn on your computer. When you see your PC manufacturer's logo or Windows logo, turn off your computer by holding the power button on the device.
- Repeat the same process two times.
- On the third time, allow your device to boot into Windows Recovery Environment (WinRE) mode.
From there, select Advanced Options > Startup Settings > Restart.
Press F4 to boot into safe mode.
If you are logged in successfully there, try resetting your PIN.
Let me know if you still need more help.
