How to fix
PIN error code 0x80090016
on Windows

Hello. I tried to set up a PIN on my Windows PC but I received the 0x80090016 error and the message "We weren't able to set up your PIN. Sometimes it helps to try again or you can skip for now and do this later." What should I do?

When the operating system is unable to establish a PIN for the device, the PIN error code 0x80090016 in Windows occurs. This error message is usually displayed alongside the prompt "Something went wrong". The problem is usually caused by a corruption of the Ngc folder,[ref en-1] which is located on the system volume.

This error can have a number of consequences for users, including preventing them from creating a PIN and logging in with it. Because the PIN is a secure way to access the device and its features, being unable to use it may cause difficulties in performing daily tasks.

To repair the corruption, one possible solution is to delete the contents of the Ngc folder. If the PIN is disabled via Windows policies, another option is to enable the "Turn on PIN sign-in" policy. To check for system file corruption, users can use the System File Checker (SFC) or DISM commands. Finally, in order to implement the most effective solution, the root cause of the problem must be identified.

In this guide, you will find 3 steps that should help you fix PIN error code 0x80090016 in Windows. Keep in mind that the troubleshooting process can be lengthy. You can use a maintenance tool like [d1] that can fix most system errors, BSODs,[ref en-2] corrupted files, and registry[ref en-3] issues. Otherwise, follow the step-by-step instructions below.

Please ensure that you are logged in as an administrator before attempting any of the following solutions. The second method will require administrative privileges since it involves accessing a directory that even administrator accounts may not have rights to.

Method 1. Fix Corrupted System Files

Use Command Prompt commands to repair system file corruption:

• Open Command Prompt as administrator
• Use the following command and press Enter:
  sfc /scannow

• Reboot your system
• If SFC returned an error, then use the following command lines, pressing Enter after each:
  DISM /Online /Cleanup-Image /CheckHealth
  DISM /Online /Cleanup-Image /ScanHealth
  DISM /Online /Cleanup-Image /RestoreHealth

Method 2. Delete Contents of the Ngc Folder

As the corruption of the Ngc folder is the likely reason for the issue, deleting the folder's contents is necessary to address it. This solution should resolve the problem and enable you to establish a PIN successfully.

• Open Windows Explorer.
• Navigate to the following directory:

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

• If you cannot see the AppData folder, enable hidden folders by clicking on File and selecting Change folder and search options.
• Switch to the View tab and ensure that the Show hidden files, folders, and drives option is checked. Hit Apply, then click OK.
• To access the Ngc folder, take ownership of it by right-clicking on the folder and clicking Properties.
• Switch to the Security tab and click Advanced.
• Click Change in front of Owner.

• Type in the username of the account that you are currently using, click Check Names, and hit OK.
• Make sure that the Replace owner on subcontainers and objects box is checked.
• Click Apply and then hit OK.
• Open up the Ngc folder and delete all the contents of the folder.
• Try adding a PIN again.

Method 3. Use the Local Group Policy

The error message may appear as a result of Windows policies that disable PIN sign-in in certain circumstances. Group Policy is a Microsoft Windows feature that allows you to centrally manage and configure the operating system and the applications that run on it.

It allows administrators to define settings for users and computers in an Active Directory environment. Group Policy settings can control almost every aspect of the Windows operating system, from user interface options to network settings. Group Policy is available in the following Windows versions - Windows Professional, Enterprise, Education, Server, etc. Group Policy is not available in the Home editions of Windows.

• Press the Windows key + R to open the Run dialogue box.
• Type in gpedit.msc and press Enter.
• Navigate to the following directory:

Computer Configuration > Administrative Templates > System > Logon

• Locate the Turn on PIN sign-in policy and double-click it to edit it.
• Set it to Enabled and then click Apply and OK.
• Restart your system for the changes to take effect.
