Have you encountered 0x000000CB DRIVER_LEFT_LOCKED_PAGES_IN_PROCESS on your Windows PC? I know how frustrating it can be.

Drivers are responsible for communication between the hardware and software. However, if a driver fails to release its memory, you may encounter this error. Continue reading to find out all about the causes and how to resolve this issue for good.


0x000000CB DRIVER_LEFT_LOCKED_PAGES_IN_PROCESS is a BSoD error. It indicates that drivers which previously locked memory are unable to unlock it now. This practically means that the drivers are unusable, and this results in a Blue Screen of Death.


In my experience, the most common causes behind this problem are:

  • Windows Update Service stopped: If the Windows Update Service is stopped, the error may occur.
  • Obsolete drivers: If the system drivers haven’t been updated for long, you might encounter the problem.
  • Corrupt Windows Update cache: The Windows Update cache could be corrupt, and this will cause the issue.
  • Missing or corrupt system files: If the System files are corrupt, it’ll result in the mentioned error.


Before trying any fix, I recommend two preliminary solutions:

1. Run the BSoD troubleshooter: The BSoD troubleshooter checks the system for basic issues that cause blue screens.

2. Try a BSoD repair tool: While you can proceed with the solutions mentioned in this article, an easier option would be to try a BSoD repair tool. A few of them are premium, but worth it if you have persistent issues.
