Fix ACTIVE_EX_WORKER_THREAD_TERMINATION in Windows 11
So, what triggers this common error on a PC? From what I’ve experienced, it usually occurs due to driver conflicts, corrupted system files, or hardware failures. To resolve the problem, you will need to take control of these very culprits.
1. Update All Device Drivers
Note that outdated or incompatible drivers are a major cause of BSOD errors like ACTIVE_EX_WORKER_THREAD_TERMINATION.
- On your PC, launch the Device Manager, right-click each device, and choose Update driver.
- You can also use Windows Update or tools like Intel Driver & Support Assistant for automatic updates.
2. Run System File Checker (SFC)
Keep in mind that corrupt system files can trigger BSODs during normal operations.
- Open Command Prompt (Admin) on your PC and run:
sfc /scannow
- This tool will automatically detect and repair corrupted or missing system files.
3. Use the DISM Tool
DISM repairs issues that SFC can’t fix, especially with system image integrity.
- In Command Prompt (Admin), run:
DISM /Online /Cleanup-Image /CheckHealthDISM /Online /Cleanup-Image /ScanHealthDISM /Online /Cleanup-Image /RestoreHealth
4. Check for Windows Updates
It’s important to mention that Microsoft keeps rolling out patches (regularly) to fix BSOD-causing bugs and compatibility problems.
- Go to the Settings app on your computer > Windows Update and click Check for updates.
- After that, install any pending updates and restart your PC.
5. Perform a Clean Boot
Third-party services or startup programs may interfere with Windows processes.
- Just press Win + R to fire up the Run dialog > type
msconfig> Go to Services. - Now, check Hide Microsoft services.
- Next, click Disable all.
- In Startup tab, disable all items and restart the PC to isolate problematic software.
6. Uninstall Recently Installed Software
No solution as yet? Try uninstalling the outdated or faulty app. I suspect that the new apps or updates are conflicting with system threads.
- On your computer, head over to Settings > Apps > Installed apps, and remove any recently added or suspicious software.
- Then, restart your computer and see if the error persists.
7. Test Your RAM with Windows Memory Diagnostic
Faulty memory modules can interrupt system operations, leading to BSODs.
- Just press Win + R, type
mdsched.exe, and follow the prompt to restart and scan memory. - Up next, replace the RAM if errors are found.
8. Scan for Malware
Should the problem persist, I’d suggest you scan for malware. Some malware programs corrupt system files or interfere with background processes.
- Run a full system scan using Windows Security (Settings app > Privacy & security) or a trusted antivirus like Malwarebytes.
- Quarantine or remove any detected threats.
9. Update BIOS/UEFI Firmware
An outdated BIOS can cause hardware and thread mismanagement.
- Visit your motherboard or laptop manufacturer’s website and follow their guide to safely update your BIOS.
10. Reset or Reinstall Windows
If nothing has come to your rescue, the issue might lie deep in your system configuration. Hence, try resetting or reinstalling Windows.
- Navigate to Settings > System > Recovery.
- After that, choose Reset this PC, and choose to keep your files or remove everything.
