While trying to install the latest feature updates, your computer may fall into a BSOD error prompting this Stop Code “PAGE FAULT IN NONPAGED AREA” along with the reason for the failure of the hardlock.sys file. You may assume the hardlock.sys is an external hardware file, but, it isn’t. This third-party-developed file is a valid one. It is located inside the drivers folder of the System32 directory. Follow these easy steps to solve the issue. Usually, a simple registry edit should do the trick. But, if that doesn’t work, deleting the older HASP driver should resolve the issue.

Fix 1 – Tweak the registry

Try modifying the registry on your machine so that this hardlock.sys doesn’t cause this problem.

1. You can invoke the search box using the Windows+S keys together and then, write “regedit“.

2. After that, tap “Registry Editor” which appears in the search results.

When you have modified the value of the Start, exit the Registry Editor. This modification won’t take place until you restart the system.

After restarting your computer, retry installing the windows updates once more.


Fix 2 – Uninstall the driver

Uninstalling the older HASP License driver is possible only with the haspdinst package extracted in C drive. So, follow these steps to uninstall that –

You can not extract this into a subdirectory of the C drive.

2. Once you have extracted it, use the search box to type “cmd“.

3. Then, right-click the “Command Prompt” in the search results and tap “Run as administrator“.
