Windows error: Hardlock.sys error crashes PC

There is a Windows error that occurs for certain users of SignalPro that causes the machine to crash or get the “blue screen of death”. This error occurs when the user attempts to install a Windows feature update, cumulative update and any version of SignalPro onto their machine.

THIS IS NOT AN ERROR BY SIGNALPRO. This error is related to Windows but is caused by the installation of any application or windows update or sometimes SignalPro. We have had customers find success following these steps:

1 - Modify the registry

Since this is a registry operation, it is recommended that you back up the registry or create a system restore point as necessary precautionary measures. Once done, you can proceed as follows: Press Windows key + R to invoke the Run dialog.

  • In the Run dialog box, type regedit and hit Enter to open Registry Editor.

  • Navigate or jump to the registry key path below:

1 HKLM\SYSTEM\CurrentControlSet\Services\Hardlock
  • At the location, on the right pane, double-click on Start entry to edit its properties.

  • In the properties dialog, set its Value data as 4.

  • Click OK to save changes.

Now you may try to install SignalPro

2 - Update driver

  • Press Windows key + X to open the Power User Menu.

  • Press M key on the keyboard to open Device Manager.

  • On the Device Manager console, locate and expand the device’s list to see Sentinel driver.

  • Once you see it, do a right-click on it and select Update Driver.

  • Choose Search automatically for drivers from the next window.

  • Follow the onscreen prompts to complete the driver update.

3 - Uninstall Windows Update.

Sometimes, this error occurs after the installation of certain Windows Updates. So, if the issue happens to appear just after installing the updates, you can uninstall the update and see if this fixes the problem.
