How to Clean Boot Windows 11 (Step-by-Step)

A clean boot starts Windows 11 with only the essential Microsoft services and drivers, temporarily disabling startup programs, third-party services, and non-critical processes. This helps you diagnose software conflicts, speed up troubleshooting, or prepare for driver and app installations. You don’t need any special tools—just administrator access to your PC.

What You’ll Need

• A Windows 11 PC with an administrator account
• Your login password (if you use one)
• About 10–15 minutes of time

Step-by-Step

1. Open System Configuration. Press Win + R to open the Run dialog, type msconfig, and press Enter. If prompted by User Account Control, click Yes.
2. Go to the Services tab. In the System Configuration window, click the Services tab at the top.
3. Hide Microsoft services. Check the box that says Hide all Microsoft services at the bottom-left. This prevents you from disabling critical Windows components.
4. Disable all third-party services. Click Disable all. This turns off everything that isn’t a Microsoft service—like antivirus helpers, GPU utilities, and background updaters.
5. Open the Startup tab. Click the Startup tab next to Services. Note: you can’t disable startup items here directly; it will open Task Manager.
6. Open Task Manager. Click Open Task Manager in the Startup tab. If you don’t see it, click the link that says “Open Task Manager” under the list.
7. Disable startup apps. In Task Manager, you’ll see a list of apps that run at startup. Right-click each one and select Disable. Do this for every item in the list. Close Task Manager when done.
8. Go back to System Configuration. Return to the System Configuration window (it should still be open). Click OK at the bottom.
9. Restart your PC. A dialog will appear asking if you want to restart now or later. Choose Restart to apply the clean boot state immediately.
10. Test your issue. After Windows restarts, try to reproduce the problem you were having (e.g., a crash, slow startup, or error message). If the issue is gone, you’ve confirmed a software conflict.
11. Exit clean boot when done. To return to normal startup, open msconfig again, go to the General tab, select Normal startup, and click OK. Then restart your PC.

Common Mistakes

• Forgetting to hide Microsoft services. If you don’t check “Hide all Microsoft services,” you might disable critical services like Windows Update or networking, causing more problems.
• Disabling startup apps in the wrong place. Some users try to disable startup items in the Services tab—that only affects services, not apps. You must use Task Manager for startup apps.
• Not restarting after changes. The clean boot won’t take effect until you restart. Skipping the restart means you’re still testing the old configuration.
• Leaving clean boot on permanently. Running Windows with all third-party services disabled long-term can break features like printer drivers or audio. Always revert to normal startup after testing.
• Disabling services that are not third-party. Some services may not be marked as Microsoft but are still needed (e.g., Intel or AMD chipset drivers). If unsure, leave them enabled.

Tips

• Use clean boot for driver installs. If you’re installing a GPU or audio driver, a clean boot prevents old services from interfering, making the installation smoother.
• Keep a list of what you disabled. Before you disable anything, take a screenshot or write down the names. This makes it easier to re-enable specific items later.
• Test in stages. If the issue disappears in clean boot, re-enable services in groups (e.g., half at a time) to isolate the culprit faster.
• Use the “Normal startup” option to exit. Don’t just re-enable services manually—use the General tab to reset everything at once.
• Check for Windows updates after reverting. Some updates require a normal startup to install correctly.

Troubleshooting

• Windows won’t start after clean boot. If your PC fails to boot, press F8 during startup (or use a recovery drive) to access Safe Mode. From there, open msconfig and select Normal startup, then restart.
• You can’t open System Configuration. If msconfig won’t run, try searching for “System Configuration” in the Start menu. If that fails, run sfc /scannow in an elevated Command Prompt to repair system files.
• The issue still happens in clean boot. This means the problem is likely not caused by third-party software. It could be a hardware issue or a Windows system file problem. Run DISM /Online /Cleanup-Image /RestoreHealth and then sfc /scannow.
• You disabled a service that broke networking. If you lose internet access, restart in Safe Mode, re-enable all services, and then selectively disable them one by one to find the culprit.
• Task Manager shows no startup items. Some apps hide from the startup list. Check the Services tab again—some “apps” are actually services. If you still can’t find it, use the App startup section in Settings > Apps > Startup.

Frequently Asked Questions

What’s the difference between clean boot and Safe Mode?

Safe Mode loads only the absolute minimum drivers and services, with no networking by default. Clean boot loads all Microsoft services and drivers but disables third-party ones, so you still have full functionality like internet and graphics.

Will clean boot delete my files or apps?

No. Clean boot only changes which services and startup apps run. Your files, applications, and personal data remain untouched.

How do I know which service is causing the problem?

After confirming the issue is gone in clean boot, re-enable services in batches (e.g., 10 at a time) and restart each time. When the issue returns, you’ve found the culprit.

Can I use clean boot to speed up my PC permanently?

Not recommended. Clean boot is a diagnostic tool, not a performance setting. For permanent speed gains, disable unnecessary startup apps in Task Manager and set services to “Manual” instead of “Automatic.”

Do I need to re-enable everything after testing?

Yes. Leaving your PC in clean boot state can cause issues with printers, audio, and other hardware. Always switch back to Normal startup after you finish troubleshooting.

Will clean boot fix a blue screen error?

It can help identify if a third-party driver or service is causing the blue screen. If the error doesn’t occur in clean boot, you’ve isolated it to a non-Microsoft component.
