Splwow64.exe is a Windows process related to printing on 64-bit versions of Windows. Sometimes, errors with this file can interrupt your printing tasks or affect system performance. Fixing these errors is usually straightforward if you follow the right steps carefully.

In this guide, we will walk you through simple troubleshooting methods to resolve Splwow64.exe errors on Windows 11. Each step is explained clearly, so even beginners can follow along without confusion.

Before diving into complex solutions, it’s important to start with the basics. Many issues can be fixed by simply ensuring your system settings and files are correct.

Let’s begin with some quick checks and prerequisites you should verify first.

Quick Note: Prerequisites and Initial Checks

  • Check for Windows Updates: Sometimes, Microsoft releases fixes for common issues through updates. Make sure your Windows 11 is fully updated.
  • Restart Your Computer: A simple restart can clear temporary glitches causing the error.
  • Confirm Printer Connection: Ensure your printer is properly connected and powered on.
  • Scan for Malware: Malicious software can interfere with system files. Run a full antivirus scan to rule out infections.

Step 1: Restart the Print Spooler Service

The print spooler is a service that manages print jobs. Sometimes, restarting it can clear stuck processes related to Splwow64.exe.

  1. Press Windows + R to open the Run dialog box.
  2. Type services.msc and press Enter to open the Services window.
  3. Scroll down and find Print Spooler.
  4. Right-click on it and select Restart.
  5. Wait a few moments and try printing again.

Why this helps: Restarting the print spooler clears any stuck print jobs and resets the service, which can often fix errors caused by corrupted spooler data.

Step 2: Clear the Print Spooler Files Manually

If restarting the spooler doesn’t work, you may need to clear the print queue files manually. These files can become corrupted and cause errors.

  1. Press Windows + R, type services.msc, and press Enter.
  2. Find Print Spooler, right-click, and choose Stop.
  3. Open File Explorer and navigate to C:WindowsSystem32spoolPRINTERS.
  4. Delete all files inside the PRINTERS folder. These are temporary print jobs.
  5. Go back to Services, right-click Print Spooler, and select Start.
  6. Try printing again to see if the error is resolved.

Why this helps: Removing stuck or corrupted print job files forces the spooler to start fresh, often eliminating errors linked to Splwow64.exe.

Step 3: Update or Reinstall Printer Drivers

Outdated or faulty printer drivers often cause errors with Splwow64.exe. Updating or reinstalling drivers can solve compatibility issues.

  1. Press Windows + X and select Device Manager.
  2. Expand the Printers or Print queues section.
  3. Right-click on your printer and choose Update driver.
  4. Select Search automatically for updated driver software and follow the prompts.
  5. If no update is found or the problem persists, right-click the printer and select Uninstall device.
  6. Restart your computer; Windows will attempt to reinstall the driver automatically.
  7. Alternatively, visit the printer manufacturer’s website to download the latest driver and install it manually.

Why this helps: Using the latest driver ensures your printer works smoothly with Windows 11 and reduces the chance of system file conflicts.

Step 4: Run the Printer Troubleshooter

Windows 11 includes a built-in troubleshooter that can detect and fix common printing problems automatically.

  1. Click the Start button and open Settings.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Printer and click Run.
  4. Follow the on-screen instructions to complete the troubleshooting process.
  5. Restart your computer if prompted.

Why this helps: The troubleshooter automatically checks for issues with your printer and attempts to fix them without needing advanced user input.

Step 5: Check for System File Corruption

Sometimes, corrupted system files can cause errors with Splwow64.exe. Running a system file check can identify and repair these problems.

  1. Press Windows + S, type Command Prompt, right-click it, and select Run as administrator.
  2. Type the following command and press Enter:
sfc /scannow

This process will scan and repair damaged system files. It may take several minutes. After it finishes, restart your PC and check if the error persists.

Why this helps: System file corruption can affect many Windows processes, including Splwow64.exe. Repairing these files restores system stability.

Alternative Method: Use DISM Tool for Advanced Repair

If the System File Checker (SFC) did not fix the problem, you can use the Deployment Image Servicing and Management (DISM) tool.

  1. Open Command Prompt as administrator again.
  2. Type the following commands one by one, pressing Enter after each:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

Wait for each command to complete. Once done, restart your computer and test your printer.

Why this helps: DISM repairs the Windows image itself, which can fix deeper issues that SFC cannot resolve.
