Repairing Windows 11 through Command Prompt sounds intimidating—trust me, it’s not as bad as it sounds. All it takes is diving into a few simple commands, and suddenly your system can shake off corrupt files or boot hiccups. Sometimes Windows glitches or crashes happen out of nowhere, often due to corrupted system files or disk errors. Running these commands can help identify and fix those issues without pulling out the heavy artillery of reinstalling everything.
How to Repair Windows 11 Using Command Prompt
Using the command prompt can be a real lifesaver if your Windows 11 isn’t running smoothly or you’re getting weird errors. Here’s how to do it, step by step:
Step 1: Open Command Prompt as Administrator
Hit the Windows key, type “cmd,” then right-click on ‘Command Prompt’ and choose Run as administrator. This might seem obvious, but it’s super important. Some commands get grumpy if you’re not running with admin rights, and you’ll get errors or nothing at all.
On some setups, you might even be prompted for permission or a password. Don’t skip this step—otherwise, the commands won’t do what they’re supposed to.
Step 2: Run System File Checker (SFC)
Type sfc /scannow and hit Enter. This scans your system for broken or missing files and tries to repair them automatically. It’s like a health check for your Windows core files. Might take some time, so grab a coffee or whatever, because it can hang for a bit.
On some machines, this step fails the first time or gets hung up, especially if your disk has issues. Sometimes rebooting and running it again helps. When it’s done, you’ll see a report—either everything’s fine or it fixed some files.
Step 3: Use DISM Tool
Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter. This is more advanced—handles problems the SFC can’t fix. It repairs the Windows image that’s used to rebuild your system files.
Important: if this command gets stuck or fails, try running it in Safe Mode or after a system restart. On some hardware, it takes a while or needs the network to be active because it pulls resources online.
Step 4: Check Disk for Errors
Type chkdsk /f /r and hit Enter. You might get a message saying it can’t run immediately because the disk is in use. If so, just type Y when prompted and then restart your PC.
This command scans for bad sectors and fixes logical errors. Expect it to take a while on larger drives, but it’s super worth it. Keeps your data safe and your system running smoother.
Step 5: Restart Your Computer
Once all that’s done, give your system a reboot. This allows Windows to apply all the fixes, and sometimes a restart is all that’s needed to clear out residual glitches.
After that, your system should feel a bit healthier. Think of it as giving Windows a tune-up—sometimes just cleaning out the bad files and fixing disk errors can boost performance or fix weird crashes.
Tips for Repairing Windows 11 Using Command Prompt
- Always back up your stuff before running these commands. Just in case, better safe than sorry.
- Keep your PC plugged in—these scans and repairs can take a while, and you don’t want it dying mid-way.
- Make sure Windows and drivers are up to date—prevents some issues in the first place.
- Learn a few basic commands if you’re into troubleshooting—can save you a lot of hassle next time.
- If stuff still isn’t right, sometimes a repair install or reset is needed, but try these commands first.
Frequently Asked Questions
What does the SFC tool do?
It scans your Windows system files for corruption or damage and repairs them if needed. Basically, it makes sure your core files are in good shape.
Can I run these commands in safe mode?
Yeah, safer and sometimes more effective. Safe Mode loads only the essentials, so corrupted files or disk errors might be easier to fix there.
What if SFC finds errors but can’t fix them?
This is where DISM comes in. Running DISM /Online /Cleanup-Image /RestoreHealth often helps fix underlying image issues that prevent SFC from repairing files.
Is it safe to run these commands on any computer?
Generally, yes, but don’t forget to back up your personal files first. Better safe than sorry, especially if your system’s already acting flaky.
How often should I run these diagnostics?
If your system starts acting weird or after updates, give it a run. Otherwise, bi-monthly checks are a good habit—not too often, not too sparse.
Summary
- Open Command Prompt as Administrator.
- Run
sfc /scannow. - Use

Conclusion
Honestly, running these commands can feel like giving your Windows a quick reset—it’s not as intimidating as it sounds. Sometimes, just fixing corrupted files or bad sectors is enough to make everything run smoother again. Of course, these are tools in your toolbox, and regular maintenance, updates, and backups keep things healthy long-term. But don’t be scared to go into the command prompt if things go sideways—most of this stuff is straightforward, and it can save a lot of frustration. Just a heads-up: if stuff still breaks after this, it might be time for more drastic measures, like a clean install or contacting tech support.
