Step-by-Step Guide to Fix Windows System Error Code ERROR_42
Step 1: Restart Your Computer
Sometimes, a simple restart can clear temporary glitches:
- Save all work, close open apps.
- Click on Start > Power > Restart.
- Check if the error still appears after reboot.
Step 2: Identify the Device Causing ERROR_42
- Press Windows + X and select Device Manager.
- Look for any devices with a yellow triangle or exclamation mark. These are likely problematic devices triggering ERROR_42.
- Right-click on the faulty device and select Properties. Check the Device status to see the error description.
Step 3: Update the Device Driver
- In Device Manager, right-click the problematic device.
- Select Update driver > Search automatically for updated driver software.
- Windows will search online and attempt to install the latest driver.
- Restart your PC and check for error resolution.
Step 4: Roll Back the Driver (If You Recently Updated)
If ERROR_42 started after a recent driver update, rolling back might help:
- In the device’s Properties window, go to the Driver tab.

Step 5: Use Windows System File Checker (SFC) to Repair Corrupt Files
Corrupted system files can cause driver errors:
- Press Windows + S, type cmd.

-
Type the command below and press Enter:
sfc /scannow
- Allow the scan to complete. If it finds corrupt files, it will attempt to repair them.

Step 6: Run the Deployment Image Servicing and Management (DISM) Tool
If SFC doesn’t fix the issue, use DISM to repair Windows system images:
- Open Command Prompt as administrator again.
-
Type and run:
DISM /Online /Cleanup-Image /RestoreHealth
- Wait for the process to complete (this may take some time).
- Restart your computer.
Step 7: Uninstall and Reinstall the Problematic Device
- Return to Device Manager.
- Right-click on the faulty device and select Uninstall device.
- Confirm any prompts.
- Restart your PC to let Windows detect and reinstall the correct driver automatically.
Step 8: Check for Windows Updates
Microsoft regularly releases fixes and driver updates:

Step 9: Scan for Malware and Viruses
Malicious software can corrupt drivers and system files:
- Run a full system scan with Windows Defender or a trusted third-party antivirus program.
- Quarantine or remove any threats found.
- Restart the PC and see if the error persists.
Step 10: Perform a System Restore (Last Resort)
If nothing else works, restore your PC to a point where the error didn’t exist:
- Press Windows + S, type Create a restore point, and open it.
- Click System Restore > Follow the wizard to select a restore point.
- Confirm and wait for the system to roll back.
- Check if your problem is resolved.
