5 Best Ways to Fix Hardlock.sys Error in Windows 10

Windows updates have long been plagued with issues since Microsoft’s inception. Things frequently break, and users often encounter the dreaded BSOD (Blue Screen of Death) error. The recent October update is no exception. At the bottom of the screen, you may encounter the message ‘What failed: hardlock.sys’. Another error that may appear is ‘Page_Fault_in_Non-Paged_Area’.

5 Best Ways to Fix Hardlock.sys Error in Windows 10

You can find the hardlock.sys file in this folder: C:\Windows\System32\drivers. What’s notable is that this file is not essential for running your Windows10 computer. It was developed by a third-party vendor but has been signed by Microsoft. However, deleting the file is not recommended. There are ways to fix the issue, which we will discuss below.

1. Registry Editor

Always make a restore point before making system-level changes or installing a major Windows update.

Step 1: Open the Registry Editor from the Start menu. Admin rights will be required.

Step 2: Navigate to the following folder structure:

HKLM\SYSTEM\CurrentControlSet\Services\Hardlock

Step 3: If the Hardlock folder is missing, no action is needed. If it is present, double-click on the Start entry in the right window-pane and set the value data as 4. Save all changes.

Reinstall the latest Windows 10 update and check for the BSOD hardlock.sys error.

2. Hardlock Device Driver

We have written a guide on drivers, but not everyone can access the system due to the BSOD error. So, I will share a CMD hack that you can use in Safe Mode instead. We are going to uninstall the Hardlock Device Driver.

Step 1: Open CMD from the Start menu by selecting the ‘Run as administrator’ option.

Reboot your computer once and try updating Windows again. Check if you still get the hardlock.sys error.

3. Uninstall Sentinel Driver

Open your computer in Safe Mode if you can’t access drivers from the Device Manager normally.

Step 1: Search for and open the Device Manager from the Start menu. You will find all the drivers installed on your Windows 10 computer. Step 2: Scroll to the bottom of the window to find Universal Serial Bus controllers. Double-click to expand it. You should find a driver entry that says ‘Sentinel HASPKey’ or ‘Sentinel USB Key’.
