How to fix DRIVER_LEFT_LOCKED_PAGES_IN_PROCESS Blue Screen in Windows?

Issue: Hello, I have been recently encountering some crashes with the DRIVER_LEFT_LOCKED_PAGES_IN_PROCESS error code. Could you please assist in resolving this?

Solved Answer

DRIVER_LEFT_LOCKED_PAGES_IN_PROCESS is an error message that typically appears in the Windows operating system. It occurs when a device driver or a system component has failed to unlock memory pages that it had previously locked. This error can lead to system crashes, instability, and other performance issues. It is usually caused by a bug in the driver or a software conflict.

DRIVER_LEFT_LOCKED_PAGES_IN_PROCESS BSOD might occur at any time – whenever users are booting into Windows, launching programs, or even doing nothing significant at the time. At this point, the system freezes, and the blue screen is shown, which is accompanied by a generic BSOD text along with the error code 0x000000CB.

While for some, this might be a one-time thing, others suffer from repeated crashes, and, in some rare cases, users might not even be able to access their Windows at all due to the reboot loop. This can be particularly problematic, making troubleshooting in normal mode impossible.

Luckily, there are some solutions you could try to fix the DRIVER_LEFT_LOCKED_PAGES_IN_PROCESS error and stop these crashes. The exact cause of the error and the solution will depend on the specific circumstances in which it occurs.

For example, it might be caused by corrupted system files, in which case you could repair it with conning commands via Command Prompt or by employing an automatic PC repair tool FortectMac Washing Machine X9. In other cases, lack of space on the disk may also result in DRIVER_LEFT_LOCKED_PAGES_IN_PROCESS crashes – clearing the disk from junk can be helpful in this case.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
