PIN broke after Windows update

You didn't even read my issue.

I CAN NOT. *NOT*. AM UNABLE. AM FORBIDDEN TO. Log into the PC.

I am UNABLE to sign into the PC because NEITHER the PIN not the password will work to unlock the machine and I'm stuck at the login screen.

I have had to reinstall Windows several times yesterday so I can replicate this issue at will. It's a MS issue and I want an actual TAC for this.

To repo:

1. Sign into a brand new Windows 11 Pro install.
2. Select Work or School account.
3. Sign in as normally.
4. Set a 6 digit PIN
5. Windows works. We can sign into Office apps. Lock and unlock the PC with a PIN.

However. When we restart the PC we can then no longer unlock it. Not with the known good password. Not with the know good PIN. Nothing.

There is a message on screen that the PIN is unable and needs to be setup (even though it already was working). When I click the link it opens a new window with those stupid rolling dots you insist on using, and then after a while a "Something went wrong" message appears.

So tell me. EXACTlY. How do I gain access to a machine and run commands as you purpose WHEN I CANNOT LOG IN?!

I noticed that you are using work or school accounts. It would be more appropriate for you to post your question here.

Taylor, Martin's response is to MY question. Our questions are similar, but not the same. If you want to have someone focus on your question specifically, you should start your own thread.

Martin, I tried three of your suggested solutions, but it did not fix the situation.

-Under "Manage how you sign in" there is no option to remove Windows Hello PIN. The slider for "Require Windows Hello sign-in for Microsoft Accounts" is turned on and the then greyed out to signify that I cannot change it.

-For the second solution, I used the 4 prompts
"takeown /f %windir%\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC /r /d y"

"icacls %windir%\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC /grant administrators:F /t"

"cd C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC"

"del /F /Q *"

When I reset the machine, its acting as if nothing changed. Same errors.

-I also created a new local account. I can log in and out of that normally. However, when I try to log back into the original account with the PIN bug, nothing has changed and I get all the same errors.

In addition, I have noticed that my night light which changes the hue of my screen is no longer matching the times input on my account. They seem to nearly be inverted, turning off at night, and on in the morning. This error happened around the same time as the PIN issue.

Dear Aaron,

Welcome to the Microsoft Community

I understand how inconvenient it can be to deal with issues logging into your computer, especially when it involves repeated manual recovery steps.

There are several steps you can take to try and resolve the issue with setting up your PIN on Windows 11 after a system update.

Remove and Recreate the PIN

Press Win + I to open Settings.

Go to Accounts > Sign-in options.

Under Manage how you sign in to your device, find PIN (Windows Hello) and click Remove.

Confirm the removal and restart your computer.

After the removal and restart, go back to Settings > Accounts > Sign-in options.

Under PIN (Windows Hello), click Add.

Follow the prompts to set a new PIN.

Clear NGC Folder

If you wish to set up a new PIN after gaining access, clear the PIN settings by resetting the NGC folder:

Open Command Prompt as an administrator (right-click the Start button and select Command Prompt (Admin)).

In Command Prompt, type the following commands to delete the NGC folder:

takeown /f %windir%\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC /r /d y

icacls %windir%\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC /grant administrators:F /t

cd C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC

del /F /Q *

Restart your PC, and you should be able to set a new PIN.

Clear TPM Information

Sometimes, clearing the Trusted Platform Module (TPM) can resolve PIN-related issues, especially if the PIN is linked to security credentials stored in the TPM. Note that clearing the TPM won't delete any files from your PC, but it may require you to reconfigure certain security features, such as Windows Hello. Here's how to clear the TPM:

Disclaimer: If you are going to modify the BIOS settings, back up all your personal files first to ensure that you do not lose data.

• Restart your PC and press the required key (usually Esc, Del, F2, or F10) to enter the BIOS settings.
• In the BIOS menu, navigate to the Security or Trusted Computing section .
• Look for the Clear TPM option and select it.
• Confirm the action and exit the BIOS.

Use Local Account and then Switch Back to Microsoft Account

If you’re using a Microsoft account, switching to a local account and then back to your Microsoft account may help resolve PIN issues.

Go to Settings > Accounts > Your info.

Click Sign in with a local account instead.

Follow the prompts to create a local account.

Once signed into the local account, go to Settings > Accounts > Your info.

Click Sign in with a Microsoft account instead.

Follow the prompts to reconnect your Microsoft account.

After switching back, try setting up the PIN again.

Perform a Repair Install

If none of the above steps work, you may consider performing a repair install of Windows. This will refresh your system files without affecting your personal data.

Disclaimer:  I always recommend that if you have important data, you should back it up before making large system changes.

• Visit the Windows 10 Download page.
• Under Create Windows 10 installation media, select Download the tool now.
• Launch the Media Creation Tool and choose Create installation media for another PC.
• Select the ISO file and save it locally.
• Once downloaded, right-click on the ISO file and select Mount.
• Run the setup.exe on the mounted drive.
• During setup, choose the option to Keep personal files and apps.
• Follow the on-screen prompts to complete the recovery installation.

After the repair install, try setting up the PIN again.

If you encounter any issues or need further assistance with any steps, feel free to ask.
