What is Windows System Error Code ERROR_128?
Before diving into the solutions, it’s helpful to understand what ERROR_128 means. Windows System Error Code 128 typically indicates a problem related to network issues, driver conflicts, or hardware communication errors. This could appear while trying to access network resources, installing certain software, or during device communication.
Common Causes of ERROR_128

Step-by-Step Guide to Fix Windows System Error Code ERROR_128
Step 1: Restart Your Computer
Sometimes the simplest fix is the best. Restarting your computer can clear temporary glitches and reset active processes that may be causing the error.
- Click Start > Power > Restart
- Wait for the system to reboot completely
- Check if the error persists
Step 2: Run System File Checker (SFC) and DISM Tools
Corrupted system files often cause various Windows errors. Running System File Checker and Deployment Image Servicing and Management (DISM) can repair these files:
-
Open Command Prompt as Administrator:
- Press Windows + S, type
cmd - Right-click Command Prompt, select Run as administrator
- Press Windows + S, type
-
Run SFC scan:
bash
sfc /scannow- Wait until the scan reaches 100%. This will repair corrupted system files if found.
-
Run DISM tool if SFC doesn’t fix the issue:
bash
DISM /Online /Cleanup-Image /RestoreHealth- This process might take several minutes. Make sure your internet is connected during this step as DISM may need to download files.
- Restart your PC and check if the error is resolved.
Step 3: Update Device Drivers
Outdated or faulty device drivers, especially network adapters, can trigger ERROR_128. Updating drivers can fix these conflicts:
- Press Windows + X, select Device Manager
- Expand categories related to your issue (for example, Network adapters)
- Right-click on your device, select Update driver
- Choose Search automatically for updated driver software
- Follow on-screen instructions if updates are found
- Restart your PC and test again
Tip: For critical devices, consider visiting the manufacturer’s website for the latest driver versions.
Step 4: Check Network Connections and Settings
Because ERROR_128 can be network-related, ensure your network is functioning properly:
- Test your internet connection on other devices
- Restart your router/modem
- Disable any VPN or proxy temporarily
-
Open Command Prompt and run the following commands to reset the network stack:
bash
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns - Restart your computer
Step 5: Temporarily Disable Third-Party Antivirus or Firewall
Sometimes, third-party security software blocks legitimate processes, causing ERROR_128:
- Temporarily disable your antivirus or firewall (refer to your software’s documentation)
- Try the action again that triggered the error
- If the error disappears, add the necessary application or process to the antivirus exceptions list
- Remember to re-enable your security software afterward to stay protected
Step 6: Perform a Clean Boot
A clean boot starts Windows with a minimal set of drivers and startup programs, helping you identify software conflicts:
- Press Windows + R, type
msconfig, and hit Enter - Go to the Services tab
- Check Hide all Microsoft services
- Click Disable all
- Go to the Startup tab, click Open Task Manager
- Disable all unnecessary startup items
- Close Task Manager and click OK on the System Configuration window
- Restart your PC and check if the error still occurs
If the error is resolved, reactivate services and startup items one by one to identify the culprit.
Step 7: Restore Your System to a Previous Point
If the error started recently, a system restore might help:
- Press Windows + S, type
rstruiand press Enter - Follow the wizard to select a restore point dated before the error began
- Confirm and start the restore process (your PC will restart)
- Check if the issue is fixed after restoration
Step 8: Contact Support or Consider Reinstallation
If none of the above solutions work:
- Contact Microsoft Support or your device manufacturer’s help desk
- As a last resort, consider backing up your files and performing a clean installation of Windows
