Microsoft has provided few free built in tools in your Windows 11 that can help you to resolve many issues with the Windows 11 such as corrupted files. Some of those tools are chkdsk, DISM and SFC.
The “Deployment Image Servicing and Management” tool (DISM) is a helpful, but advanced tool to scan, alter, and repair any Windows 11 system issues. A lot of OS problems such as poor performance, boot-up issues or specific crashes can come down to a corrupted system file.
Before you run the DISM repair, it’s important that you run a disk check to spot and repair any issues in the file system. Not doing this will render the follow up DISM and SFC repairs useless.
How to run chkdsk tool ?
- Open Command Prompt as administrator
- Enter this command
- Press Enter
You will then see a prompt to run this disk check on restart, type Y and press Enter again. From this point, when you restart the computer, it will perform the check.
The startup process will give you an option to skip the disk check if you need to get to Windows quickly. If you don’t need to open fast, do not interrupt the disk check and leave it to do its thing.
How to run DISM tool ?
- Open Command Prompt as administrator
- Enter this command
- Press Enter
This will command the DISM tool to do a quick sweep of the system and verify any corrupted data. More deep scan and identify corruptions you use different switch
This will take some time, but will identify the specific file corruptions. If any corruption has been find run this command to fix it
Just like ScanHealth, this will take some time, and it may look like it’s frozen when you see the % progress bar stop for a while. But trust the system — it’s downloading and replacing the corrupted files you find. Sit tight, it will take some time to complete.
The last free tool is SFC – System File Checker – If your issues are more about the setup of Windows itself, or if you want to double check that DISM did the trick, that’s where the System File Checker (SFC) comes in.
- Open Command Prompt as administrator
- Enter this command
- Press Enter
This will do a sweep of everything and repair any system files using your (now fixed) local image files. Make sure that if any errors are found, you run it a couple more times. SFC /scannow has a bit of a reputation for not fixing much the first time around.
