Fixing spoolsv.exe errors and high CPU usage on Windows 11 is usually straightforward. It involves checking the print queue, restarting services, or updating drivers. You don’t need to be a tech expert to follow these steps.

In this article, we’ll walk you through simple and detailed solutions to resolve these problems. Each step is explained clearly so you can understand why it’s important.

By the end, you should have a smoother printing experience and improved system performance.

Quick Note Before You Start

Before diving into fixes, make sure you:

  • Have administrator access on your Windows 11 PC. Some steps require it.
  • Save your work. Restarting services or your PC may close open programs.
  • Ensure your printer is properly connected and turned on.
  • Check that Windows 11 is up to date by running Windows Update.

Step 1: Clear the Print Queue

A common cause of spoolsv.exe errors and high CPU use is a stuck print job. When one job gets stuck, it can jam the entire spooler process.

To clear the print queue:

  1. Press Windows + R keys to open the Run dialog.
  2. Type services.msc and press Enter.
  3. In the Services window, find and right-click Print Spooler, then select Stop.
  4. Open File Explorer and navigate to C:WindowsSystem32spoolPRINTERS.
  5. Delete all files inside the PRINTERS folder. These are pending print jobs.
  6. Go back to the Services window, right-click Print Spooler, and select Start.

This step clears any stuck print jobs that might be causing errors or high CPU usage. Restarting the spooler service allows it to work fresh.

Step 2: Restart the Print Spooler Service

Sometimes, simply restarting the spooler service can fix temporary glitches causing CPU spikes or errors.

To restart the service:

  1. Open the Run dialog (Windows + R), type services.msc, and press Enter.
  2. Find Print Spooler in the list.
  3. Right-click and choose Restart.

This process stops and starts the service quickly, helping to clear minor faults.

Step 3: Update or Reinstall Printer Drivers

Outdated or corrupt printer drivers can cause the spooler to misbehave. Updating or reinstalling drivers often resolves these issues.

To update your printer driver:

  1. Click the Start button and select Settings (gear icon).
  2. Go to Bluetooth & devices and then Printers & scanners.
  3. Select your printer and click Remove to uninstall it.
  4. Visit your printer manufacturer’s website and download the latest driver for Windows 11.
  5. Install the driver following the on-screen instructions.
  6. Add the printer again through Printers & scanners settings.

Updating drivers ensures compatibility and can fix bugs that cause spooler errors and CPU overload.

Step 4: Run the Windows Printer Troubleshooter

Windows 11 includes a built-in troubleshooter to detect and fix common printer problems automatically.

To use it:

  1. Open Settings.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Printer and click Run.
  4. Follow the prompts to let Windows diagnose and fix issues.

This tool can find problems you might miss and apply fixes instantly.

Step 5: Check for Malware

Malware can disguise itself as legitimate system processes like spoolsv.exe and cause high CPU usage. It’s important to rule this out.

To scan your PC:

  1. Open Windows Security by searching it in the Start menu.
  2. Click Virus & threat protection.
  3. Choose Quick scan or Full scan and wait for the process to complete.
  4. Follow any instructions if malware is detected.

Keeping your system clean helps avoid unexpected errors or slowdowns.

Step 6: Advanced Option – Reset Print Spooler Components

If the problem persists, resetting the spooler components can help. This involves deleting spooler registry entries and files. Be cautious and create a system restore point before proceeding.

To reset spooler components:

  1. Open Command Prompt as Administrator (search for cmd, right-click, and choose Run as administrator).
  2. Type the following commands one by one, pressing Enter after each:
net stop spooler
del /Q /F /S "%systemroot%System32spoolPRINTERS*.*"
reg delete "HKLMSYSTEMCurrentControlSetControlPrintPrinters" /f
net start spooler

This clears all printer settings and queued jobs, resetting the spooler to a clean state.
