Fixing system files on Windows 11 might not be the most exciting task, but it’s a fair dinkum must when your PC starts playing up—crashes, error messages, you know the drill. First thing, you’ll need to open up the Command Prompt with admin rights. Yeah, I know, Windows loves to keep that bit a bit sneaky. To do it, click the Start button, type CMD, then right-click on “Command Prompt” and select Run as administrator. If a User Account Control prompt pops up, hit Yes. This step’s pretty important—without it, your commands won’t do their thing, and you’ll just be spinning your wheels.
Step 1: Run the System File Checker (SFC)
Once you’re in, type sfc /scannow and press Enter. This kicks off the built-in tool that scans your system for any corrupted or missing files. Sometimes it runs smoothly and fixes minor issues; other times, it might get stuck or show errors—probably because of permission hiccups or interrupted processes. It can take anywhere from 5 to 20 minutes, so grab a cuppa and be patient. SFC will automatically replace damaged files with healthy copies from a cache stored at C:\Windows\System32\dllcache. Sometimes, Windows likes to drag its feet or ignore the repairs, but don’t get too down if it doesn’t fix everything straight away.
Step 2: Use the DISM Tool if You Still Have Problems
If after running SFC, issues are still hanging about, it’s time to give DISM a go. Type DISM /Online /Cleanup-Image /RestoreHealth and hit Enter. This command patches up the Windows image itself—kind of like fixing the blueprint before building everything else. The catch? You’ll need a decent internet connection because DISM pulls fresh files from Windows Update servers. Depending on your connection and system, it might take a while—sometimes longer than you’d like. Some folks say it fails on the first try, but if you run it again, it often sorts itself out. The idea is to fix the core image, which then helps SFC do its job much better.
Step 3: Restart and Check if Everything’s Sorted
Once both commands have finished, restart your PC. Yep, a good ol’ reboot helps clear out the cobwebs and reload everything properly. After that, see if the problems are gone. Sometimes, just running these scans does wonders for system stability. Other times, it’s just the start. The whole process might feel a bit of a pain, but trust me, it’s worth it to get rid of those nagging errors or slowdowns.
A quick tip from experience—occasionally, these tools can hang or refuse to finish, especially on older or heavily tweaked systems. If that happens, boot into Safe Mode (by holding Shift and clicking Restart, then navigating through the options) and run these commands again. That way, you avoid interference from background apps or malware. Sometimes Windows just needs that little nudge to get things sorted properly.
Tips for Repairing System Files in Windows 11
- Always back up your important stuff before messing around with system files. Better safe than sorry, especially when running commands that make deep changes to your OS.
- Make sure your device is plugged in or has plenty of juice. These scans can take a while, and you don’t want power dropping out halfway and mucking things up even more.
- Keep Windows up to date—new patches often fix bugs that cause issues with repair tools. Check for updates under Settings > Windows Update.
- If things still aren’t working, try booting into Safe Mode. It helps isolate the problem if third-party software is causing the grief.
- If you’re stuck, have a look in the Windows support forums or community pages. Sometimes, the issue runs deeper and needs a more targeted fix.
Frequently Asked Questions
What does the SFC tool do?
Basically, it scans your system for corrupted files and picks out healthy copies to replace them. Fair dinkum simple and usually enough to sort out common Windows dramas.
How long does the SFC scan take?
Usually between 5 and 20 minutes, but it depends on your PC’s age and how much damage there is. On some setups, it can take longer or seem to get stuck—don’t stress if it drags on.
Can I use my PC while the scans are running?
Not really. It might slow things down or cause the scans to miss bits. Best to step back and let it do its thing.
What if SFC doesn’t fix the problem?
Then you’ll want to run DISM, as explained above. Sometimes, the core system image is buggered beyond SFC’s reach, and DISM’s got to do the heavy lifting.
Are these tools safe?
Too right. Both are built into Windows and are designed for fixing your system files. Just type in the commands carefully, and you should be right as rain.

Hopefully, this saves some mates a bit of hassle. Corrupted system files can be a real pain, but these tools are solid as long as you follow the steps. Good luck fixing those errors, and remember—sometimes a simple restart does the trick more often than you’d think.
