What is Error Code ERROR_6?
ERROR_6 or Invalid Handle usually occurs when an application or process in Windows attempts to use a handle (an identifier for files, resources, or processes) that isn’t valid or has been closed. This can result in crashed applications, system instability, or failure to access certain files or drives.
Understanding this helps you recognize why certain software or processes may be causing the problem and how to safely fix it.
Why Does ERROR_6 Happen?
Common causes include:
- Corrupted or incompatible software
- Faulty device drivers
- Malware infection
- Corrupted system files
- Issues during system updates or installations
Before You Start: Backup Your Data
Before diving into troubleshooting, it’s smart to back up any important files. Although the steps outlined here are safe, errors during fixes (especially system-level changes) can sometimes lead to unexpected data loss.
How to Fix Windows System Error Code ERROR_6: Step-by-Step
Step 1: Restart Your Computer
Sometimes, ERROR_6 can be temporary, caused by processes stuck or system glitches.
- Click Start > Power > Restart.
- After rebooting, check if the problem persists.
Step 2: Run Windows Troubleshooter
Windows includes an automated troubleshooter that can detect and fix common system issues.
- Go to Settings > Update & Security > Troubleshoot.
- Select the troubleshooter related to your problem (e.g., Program Compatibility, Hardware and Devices).
- Follow the on-screen instructions.
Step 3: Scan Your PC for Malware
Malware infections often cause system oddities like invalid handles.
- Open Windows Security by typing it in the Start menu.
- Click on Virus & threat protection.
- Click Quick scan or run a full scan for better protection.
- Quarantine or remove any threats found.
- Restart your PC and check if ERROR_6 still appears.
Step 4: Update Device Drivers
Outdated or corrupted drivers can cause ERROR_6 errors.
- Press Windows + X and select Device Manager.
- Look for any devices with a yellow warning icon.
- To update, right-click the device and choose Update driver.
- Select Search automatically for updated driver software.
- Restart your PC after updating.
If a recent driver update caused the problem, consider rolling back the driver:
- Right-click the device > Properties > Driver tab > Roll Back Driver.
Step 5: Run System File Checker (SFC)
System File Checker will scan for and repair corrupted Windows system files that might be causing ERROR_6.
- Press Windows + S and type cmd.
- Right-click Command Prompt and select Run as administrator.
-
Type the following command and press Enter:
sfc /scannow
- Wait for the scan to complete. This may take some time.
- If corrupt files are found and repaired, restart your PC.
Step 6: Use the DISM Tool
If SFC can’t fix all issues, use DISM (Deployment Image Servicing and Management) to repair the Windows image.
- Open Command Prompt as administrator.
-
Run these commands one by one, pressing Enter after each:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth - After completion, restart your computer.
Step 7: Check for Windows Updates
Microsoft often releases patches that fix system errors.
- Go to Settings > Update & Security > Windows Update.
- Click Check for updates.
- Install any available updates and restart your PC.
Step 8: Uninstall Recently Installed Software
If ERROR_6 started after installing a program:
- Open Settings > Apps.
- Find the recently installed software.
- Click Uninstall and follow the prompt.
- Restart your computer and verify if the error is gone.
Step 9: Perform a Clean Boot
A clean boot helps determine if third-party software is causing ERROR_6.
- Press Windows + R, type msconfig, and press Enter.
- Go to the Services tab.
- Check Hide all Microsoft services.
- Click Disable all.
- Go to the Startup tab and click Open Task Manager.
- Disable all startup items.
- Close Task Manager and click OK in the System Configuration window.
- Restart your computer.
If the error disappears, enable services and startup items one by one to pinpoint the culprit.
Step 10: Seek Professional Help or Perform a System Restore
If none of the above fixes resolve ERROR_6:
- Consider restoring your system to an earlier point when everything worked (type Create a restore point in Start).
- If you’re uncomfortable doing this yourself, seek help from a trusted PC technician.
