Step-by-Step Guide to Fix ERROR_79 in Windows
Step 1: Restart Your Computer and Devices
Sometimes, what seems like a complex issue can be solved with a simple restart.
- Restart your Windows PC.
- Restart any network devices like routers, switches, and printers.
Why?
This clears temporary glitches affecting network services and print spoolers.
Step 2: Check Network and Printer Connections
- Ensure your printer is properly connected to the network or directly via USB.
- If using a network printer, verify that your PC is connected to the same network.
- Check if other devices can print to the same printer to isolate the issue.
Step 3: Clear the Print Spooler
The Print Spooler service can become corrupted, causing ERROR_79.
- Press Windows + R, type
services.msc, and press Enter. - Scroll down to Print Spooler, right-click it, and select Stop.
- Open File Explorer and navigate to:
C:\Windows\System32\spool\PRINTERS - Delete all files in the
PRINTERSfolder (you may need administrator permission). - Go back to the Services window, right-click Print Spooler, and select Start.
This process clears stuck print jobs and resets spooler state.
Step 4: Update or Reinstall Printer Drivers
Faulty drivers often trigger ERROR_79.
- Visit your printer manufacturer’s official website.
- Download the latest compatible driver for your Windows version.
- Uninstall the old driver:
- Press Windows + X → Device Manager → Expand Printers.
- Right-click your printer and choose Uninstall device.
- Install the updated driver following the manufacturer’s instructions.
- Restart your computer and test printing again.
Step 5: Run Windows Update
Windows updates often patch bugs that cause errors like ERROR_79.
- Go to Settings → Update & Security → Windows Update.
- Click Check for updates, and install any available updates.
- Restart your PC after installation.
Step 6: Run DISM and SFC to Repair System Files
System file corruption can contribute to unexpected network errors.
- Open Command Prompt as administrator (search
cmd, right-click, Run as administrator). - Type the following commands one at a time, pressing Enter after each:
bash
DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow
- Wait for the scans to complete (this might take some time).
- Restart your PC to apply any repairs.
Step 7: Disable Firewall or Antivirus Temporarily
Sometimes, your firewall or antivirus interferes with network operations.
- Temporarily disable your firewall or antivirus software (refer to their specific documentation).
- Try the operation that caused ERROR_79.
If this fixes the problem, adjust your security software settings to whitelist your printer or network devices.
Step 8: Check Event Viewer for Detailed Errors
If ERROR_79 persists, collecting more information helps.
- Open Event Viewer (
Windows + X→ Event Viewer). - Navigate to Windows Logs → System and Application.
- Look for detailed error entries around the time ERROR_79 occurred.
- Use the error codes or IDs to search for tailored fixes online or provide them to tech support.
Bonus Tips for Preventing ERROR_79 in Future
