Windows errors can be frustrating, especially when they interrupt your workflow unexpectedly. One such error, ERROR_255, often appears with little context and can leave you scratching your head. Don’t worry—this step-by-step guide is here to help you understand and fix the Windows System Error Code ERROR_255 effectively.
What Is Windows System Error Code ERROR_255?
Before diving into the fix, it’s important to understand what ERROR_255 means. This error code is not an official Windows error but is often seen in scripts, batch files, or during software execution to indicate an abnormal termination or an unknown error.
Typically, this code implies that a process or command returned an error condition outside the standard range—usually signaling failure in underlying scripts, applications, or commands.
Common Causes of ERROR_255
- Corrupt or missing system files
- Incompatible or outdated drivers/software
- Faulty scripts or batch files
- Permission issues blocking execution of commands
- Conflicts with recently installed applications or updates
Step-by-Step Guide to Fix ERROR_255
Step 1: Restart Your Computer
Sometimes, a simple reboot fixes temporary glitches that cause errors. Save your work and restart your PC before diving into more advanced troubleshooting.
Step 2: Identify the Source of ERROR_255
- If the error appears during script execution: Check which script or program is throwing the error.
- If it appears after installing new software or updates: Consider rolling back or uninstalling recent changes.
- If it occurs randomly: Proceed with system-wide checks.
Step 3: Run System File Checker (SFC)
Corrupt or missing system files may cause abnormal terminations.
- Press Windows + X and select Windows Terminal (Admin) or Command Prompt (Admin).
-
Type the following command and press Enter:
sfc /scannow
- Wait for the process to complete (this may take some time).
- If issues are found, Windows will attempt to repair them automatically. Restart your PC afterward.
Step 4: Use DISM to Repair Windows Image
If SFC didn’t fix the problem, repair your Windows image:
- Open Command Prompt (Admin) again.
-
Run the following commands one by one:
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth - Let each command complete and then restart your computer.
Step 5: Check for Driver Updates
Outdated or faulty drivers often cause unexpected errors.
- Press Windows + X and select Device Manager.
- Inspect any devices showing a yellow warning icon.
- Right-click the device and select Update driver.
- Choose Search automatically for updated driver software.
- Repeat for all critical devices (especially display adapters, network adapters, and USB controllers).
- Restart your PC afterward.
Step 6: Review and Fix Script or Application Causing ERROR_255
- If you’re running a batch file or script:
- Open the script in a text editor and check for syntax errors or unsupported commands.
- Try running the commands individually to isolate the problematic line.
- Make sure your user account has the necessary permissions to execute the script.
- For third-party applications:
- Reinstall or update the software.
- Check the application’s support forum or website for known issues related to ERROR_255.
Step 7: Run Programs as Administrator
Sometimes lack of permissions can cause abnormal termination. Right-click the program or script and select Run as administrator to see if that resolves the error.
Step 8: Perform a Clean Boot
To rule out software conflicts:
- Press Windows + R, type
msconfig, and hit Enter. - Under the Services tab, check Hide all Microsoft services, then 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 PC and check if the error persists.
- If resolved, re-enable services one-by-one to identify the culprit.
Step 9: Scan for Malware and Viruses
Malicious software can cause diverse errors, including ERROR_255.
- Run a full system scan using your preferred antivirus program.
- Use Windows Defender for a comprehensive scan:
- Go to Settings > Update & Security > Windows Security > Virus & threat protection.
- Click Quick scan or Full scan for more thorough checks.
Step 10: System Restore or Reset as Last Resort
If all else fails and ERROR_255 continues disrupting your work:
- Use System Restore to revert Windows to a previous stable state:
- Search for Create a restore point in the Start menu.
- Click System Restore and follow prompts.
- Consider resetting Windows (you can keep your personal files during reset):
