- Product
- Windows 10 / 11
- Device & OS
- Windows
- Scenario
- Attempting to sign in to a Windows PC after recent account updates, hardware modifications, or security changes.
- Observed behavior
- The lock screen displays a message stating the PIN is no longer available. Attempting password recovery or PIN reset is blocked by an unrecognizable or truncated email address.
Verify that your computer is connected to the internet from the lock screen. Have a secondary device, such as a laptop or smartphone, ready in case you need to verify your Microsoft account online or create installation media.
Use Windows Recovery Environment to Restore the System
Access the Windows Recovery Environment (WinRE) from the lock screen to bypass the standard login process and repair the OS.
The Windows Recovery Environment provides built-in tools that can help restore your system state or access advanced troubleshooting options without needing a password.
On the Windows sign-in screen, press and hold the Shift key on your keyboard while clicking the Power icon in the bottom-right corner, then select 'Restart'.
Once the PC restarts and displays the 'Choose an option' screen, select 'Troubleshoot', then click on 'Advanced options'.
Select 'Startup Repair' to fix boot issues automatically, or choose 'System Restore' to revert recent system changes that caused the PIN error.

Reset Your PC Using Windows Installation Media
If you are completely locked out and have no other user accounts, you may need to reset the PC using external media.

Frequently Asked Questions
Why does the sign-in screen show a truncated email address?
Microsoft truncates the email address (e.g., j***@outlook.com) on the sign-in screen for privacy and security purposes. It is meant to remind you of the account attached to the PC without revealing your personal information to unauthorized individuals.
What causes the 'PIN is no longer available' error in Windows?
This error is typically triggered by significant system changes, such as a major Windows update, hardware changes (like swapping a motherboard), or modifications to the computer's TPM (Trusted Platform Module) security settings.
Can I bypass the Windows lock screen without losing my files?
Yes, you can try using the 'Keep my files' option during a PC Reset, or by using 'System Restore' from the Windows Recovery Environment (WinRE) to revert your PC's system state to a point before the error occurred.
