Keeping Windows up to date often fixes bugs and installs important driver updates.

Step 3: Identify and Update Device Drivers
Outdated or corrupted drivers are a common cause of Error 436.

If no updates are found automatically, visit the device manufacturer’s website to download and install the latest drivers manually.

Corrupted system files can cause Error 436. Windows provides built-in tools to scan and repair these files.
Run System File Checker:

DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth - Once done, reboot your PC.
Step 5: Check for Malware or Viruses
Malware infecting system files can cause unpredictable errors, including Error 436.
- Open Windows Security (search in Start menu).
- Click Virus & threat protection.
- Select Quick scan or, better yet, Full scan.
- Follow the recommendations if threats are found.
- Remove or quarantine malware and restart your PC.
Step 6: Perform a Clean Boot

If the error doesn’t appear after clean boot, it confirms a software conflict. You can enable services and startup items one by one to find the culprit.
