Welcome to the Microsoft Q&A forum. Thank you for sharing the details about your Acer Nitro laptop and the PIN issue.
The error code 0x80070006 usually points to corrupted PIN configuration files or issues with Windows Hello components. Resetting temporarily clears the problem, but if the underlying PIN data remains damaged, the issue can return.
Here are some possible steps to fix that you can try:
1 - Sign in Using Your Password
- On the sign-in screen, select Sign-in options and choose your password.
- Once logged in, go to Settings > Accounts > Sign-in options.
- Under PIN (Windows Hello), verify your Microsoft account and create a new PIN.
2 - Delete Corrupted PIN Data
If the problem persists, boot into Safe Mode:
- Hold Shift and click Restart.
- Navigate to Troubleshoot > Advanced Options > Startup Settings > Restart, then press F4.
- Go to:
C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC - Enable Hidden items in File Explorer.
- Take ownership of the folder (Properties > Security > Advanced > Change owner).
- Delete all contents inside the NGC folder.
- Restart and set up a new PIN.
Please also ensure to update Windows and Drivers
- Go to Settings > Windows Update and install all updates.
- Update biometric and security drivers via Device Manager.
