User account and PIN code failure

Question

I bought a used computer as a birthday gift for my son. During the buy I created an account to be able to check that the computer was ok and it worked.

Now, a month later, to prepare the computer I have tried to log in again with the same account. I get the message that the account does not exist. So I created a new account, the one I am using now.
To proceed with the login I am prompted to create a pin-code. If I select create a pin code I get a message that it is not possible. If a select skip then I get thrown back to the locked screen.

I have tried these steps but the problem is persistent

Answer 2

Hello Simon JS, welcome to Microsoft Q&A forum.

This error is common on used/refurbished PCs due to corrupted PIN data in the NGC folder. Please try these steps:

If you can sign in with password:

• Remove existing PIN (if possible).
• Run File Explorer as Administrator.
• Go to C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\Ngc
• Delete everything inside Ngc (take ownership if needed).
• Restart and create new PIN.

If you cannot sign in at all:

• Boot to Safe Mode (hold Shift during restart > Troubleshoot > Advanced > Startup Settings > Restart > choose 4).
• In Safe Mode, follow the steps above to clear Ngc folder.
• Restart normally.

It seems like you're encountering issues with your user account and PIN code creation on your used computer. Here are some steps you can try to resolve the issue:

1. Try to create the PIN again: Sometimes, errors can be transient and may resolve themselves upon retrying.
2. Sign out and sign in again: This can refresh the session and may allow you to create the PIN successfully.
3. Reboot the device: Restarting the computer can help clear temporary issues that might be causing the problem.
4. Unjoin and rejoin the device from Microsoft Entra ID: If the device is joined to a Microsoft Entra ID, you can try unjoining it and then rejoining. To do this, go to Settings > System > About > Disconnect from organization.

If these steps do not resolve the issue, you may want to check for specific error codes that appear during the PIN creation process, as they can provide more insight into the problem. If the error persists, contacting Microsoft Support may be necessary for further assistance.
