Ways to Solve BugCheck Error 0x00000139 in Windows

Since this is a blue screen type error, you can’t boot into your device normally. So, boot your device into Safe Mode first and then attempt the following fixes to troubleshoot this Kernel error 0x139. 

1] Update all your device drivers

This Kernel Security Check Failure Error 0x139 mostly occurs because of issues within your device drivers. There’s a possibility that some of your device drivers are outdated and require an immediate update. You may confirm the same via either Device Manager or Windows Update > Optional Updates. 

Go to either of the above-mentioned places and check if any of your device drivers require an update. Device Manager is defunct these days, so you should directly check for driver or firmware updates over Windows Update. Here’s how to perform this task – 

  • Press Windows + I to launch Settings.
  • Go to Windows Update from the left navigation and then Advanced options under More options.
  • Scroll down to Additional options, and click Optional Updates under this. 

Optional Updates in Windows 11

  • All pending updates for your system will be displayed here.
  • Tick the checkboxes of all updates, and hit Download & Install

Download and Install Optional updates under Settings

  • After the updates are downloaded successfully, the system will begin installing them one after another.
  • Have patience and keep your device connected to a Power Source. 

Only when all the updates are installed successfully, and your device boots up on its own, check if the Blue Screen Error 0x139 resolves now. 

Note: Many a time, there are some issues with the device drivers, and yet Windows 11/10 doesn’t identify them on your behalf. In such cases, you are going blind with incompatible device drivers and may get into one or more BSOD Errors time and again.

2] Roll Back Recent Driver Updates

If you had recently updated some of your device drivers and this error 0x139 started occurring afterward, you must have installed some buggy updates. To overcome this issue then, you should roll back the recently updated drivers back on Windows PC. Here’s how to carry out this process –

  • Press Windows + X to launch the Power Menu and select Device Manager.
  • On the next window, expand the section containing the recently updated drivers.
  • Right-click on the specific driver and choose the Properties option.
  • Head over to the Driver tab, and hit the Roll Back Driver button.

  • After you successfully roll back the particular driver, click OK to confirm the recent changes on your computer. 
  • Close Device Manager and restart your Windows PC.

Hopefully, from the next login, you would be able to log into your device without encountering the same bug check error 0x00000139.

3] Inspect Hard disk and RAM

Blue Screen Errors may also occur when there are some bad sectors on your hard disk or when the RAM gets corrupted. There are two separate tools that can check both HDD and RAM on Windows PC and let you know if they require any replacement. 

Running CHKDSK:

chkdsk /f /r

CHKDSK Windows 11 -Blue Screen Error 0x00000139

  • Since the root drive is already in use, the console will ask – “If you really want to initiate the disk checkup the next time your system restart?”. Type “Y” without quotes and hit Enter
  • Close Command Prompt and then restart your computer. The CHKDSK will launch next and start diagnosing your system for possible corruption within the hard disk. 
  • If there are any bad sectors on your hard drive, this tool will try repairing the same. However, if the issues are beyond repair, the same will be reported back to you.

Replace your hard disk if required, and this BSOD Error KERNEL_SECURITY_CHECK_FAILURE resolves in no time. 

Inspecting Memory:

If the hard disk is all right and yet this error 0x00000139 is appearing, this must be because of corruption within your RAM. Use Memory Diagnostic Tool to diagnose and repair corruption within RAM. Here’s how to inspect Memory in Windows – 

  • Press Windows + R to launch the Run dialog.
  • Type “MdSched” on it and hit OK.
  • Windows Memory Diagnostic tool will start next. 
  • Click the first option i.e. Restart now and check for problems (recommended)

  • Wait for this tool to find and resolve issues within your RAM.
  • After this check completes, you will get to know if there were indeed some issues with your Memory or not.

If required, replace the RAM as well and check whether this resolves the error 0x00000139 on your Windows PC. 

4] Scan for Malware 

If both the hard disk and Memory are all okay, this Blue Screen Error 0x00000139 must be the result of some malware attack on your computer. This happens mostly when you use some third-party free antivirus programs. Get rid of such apps from your Windows PC and enable Windows Security. 

Assuming there was some file corruption owing to third-party antivirus interactions with the system files, you should next run the System File Checker tool. This tool will check for corruption within the system files and folders and have them repaired. Apart from fixing corrupt files and folders, this tool will also repair any missing files on your system. 

Here’s how to proceed with this task – 

  • Boot your device into Safe mode first.
  • Open the Run dialog by pressing Windows + R.
  • Type CMD and press Ctrl + Shift + Enter keys altogether. 
  • The User Account Control window will prompt next, hit Yes to authorize accessing the CMD as administrator.
  • Type the following near the blinking cursor and press Enter –

sfc /scannow

SFC - Blue Screen Error 0x00000139

  • Wait for the next 10-15 minutes while this tool checks and repairs the corrupt system files and folders on your PC.

After this scanning/repairing process is over, you may boot back into Windows normally and check if the Blue Screen Error 0x00000139 resolves this way.

5] Check for Windows Updates

One should always keep his/her Windows Operating System up to date by downloading and installing the recent patch updates. This, in turn, ensures your device meets all the security requirements to tackle the latest vulnerabilities and malware. Moreover, Microsoft also releases new updates catering the new issues and bug check errors. 

You may download updates directly from Settings > Windows Update, or visit Microsoft’s Update Catalog and download the recent updates for your PC based on your system architecture. 

Note: Here’s a detailed guide on how to install pending updates manually on Windows 11. For this, you must boot into Safe Mode with networking on your computer. 


Hopefully, the above fixes must resolve the Blue Screen Error 0x00000139 on your Windows PC. However, if the error persists even after applying the above fixes, you should seek further assistance from a computer technician or Microsoft support to diagnose and resolve the issue.
