How to Fix Windows PIN Sign-In Fails After an Update
Question details
The user is unable to log into Windows using their PIN following a system update, and lacks access to the associated recovery phone number, password, or Microsoft account recovery.
- Product
- Windows OS
- Device & OS
- Windows
- Scenario
- Attempting to sign in to a Windows PC after a recent system update has been installed.
- Observed behavior
- The PIN sign-in fails or is rejected, and standard account recovery methods are inaccessible, leaving the user locked out of the device.
Ensure your computer is plugged into a stable power source, as you will be navigating advanced startup options that require uninterrupted power to prevent system corruption.
Uninstall the Latest Quality Update via Advanced Startup
This method removes the recent update that may have corrupted the PIN or TPM data, restoring normal sign-in functionality without needing the current PIN.
Since the Windows environment is inaccessible, you must trigger the Advanced Boot Options directly from the sign-in screen. Uninstalling the recent quality update will not delete your personal files, but it will revert system files to the state they were in prior to the update.
On the Windows sign-in screen, press and hold the 'Shift' key on your keyboard. While holding 'Shift', click the Power icon in the lower-right corner and select 'Restart'.
Once the computer restarts into the 'Choose an option' blue screen, navigate to 'Troubleshoot' > 'Advanced options' > 'Uninstall Updates'.
Select 'Uninstall latest quality update'. Follow the on-screen prompts to confirm and complete the uninstallation process. Afterward, restart your PC and attempt to sign in with your PIN again.
Perform a System Restore
System Restore rolls back your entire Windows system to a previous point in time before the update caused the PIN failure.
Boost Your Productivity with WPS Office
While resolving Windows sign-in issues, you might also be looking for reliable software to handle your documents once you regain access. WPS Office is a powerful, free, and lightweight alternative to Microsoft Office that provides a seamless productivity experience without expensive subscriptions.
- 1. Download the Installer: Visit the official WPS Office website and download the free installation package for Windows.
- 2. Install WPS Office: Run the downloaded file and follow the straightforward on-screen instructions to install the suite on your PC.
- 3. Access Your Files Seamlessly: Open WPS Office to instantly view, edit, and manage all your existing Microsoft Office documents.
Frequently Asked Questions
Why did my Windows PIN stop working immediately after an update?
Windows updates can occasionally cause system glitches or corrupt the data in the Trusted Platform Module (TPM), which securely stores your PIN. When this happens, Windows fails to recognize the correct PIN.
Will uninstalling the latest Windows update delete my personal files?
No, uninstalling a quality or feature update from the Advanced Boot Options only rolls back system files and patches. Your personal documents, photos, and files remain untouched.
What should I do if my Microsoft account recovery phone number is unavailable?
If you cannot use your recovery email or phone number, you will need to fill out the Microsoft Account Recovery form online from another device, or contact Microsoft Support directly to verify your identity.
Is it safe to permanently disable Windows Updates to prevent this?
Disabling Windows Updates is highly discouraged as a general practice. Updates contain vital security patches that protect your PC from vulnerabilities and malware.
