Windows 10 and 11 repair and maintenance commands – IT Solver Support

If you suspect there's any inconsistencies with your Windows system files, try running through the below process.

Step 1: System File Checker

Run cmd.exe as an administrator

sfc /scannow

Check the results:

If no corrupt files found, skip step 2.
If corrupt files found and successfully repaired them, go to step 2.

Optional: review the corrected files by filtering for lines with "DEPLOY " in the CBS.log

findstr /c:"DEPLOY " %windir%\logs\cbs\cbs.log > sfcdetails.txt
notepad sfcdetails.txt

Step 2: Run an online repair

DISM /Online /Cleanup-Image /RestoreHealth

Once it's done - restart your computer.

Step 3: Check disk for errors

To run a CHKDSK on the C: drive on Windows 11, you can follow these steps:

Open the Start menu and search for "Command Prompt"
Right-click on the Command Prompt app and select "Run as administrator"
Type "chkdsk C: /f" and press Enter. The "/f" flag tells CHKDSK to fix any errors it finds on the drive.
Wait for the CHKDSK process to complete. This may take some time, depending on the size of the drive and the number of errors found.

Review the results by checking the Event Viewer for any entries related to the CHKDSK.

Open the Start menu and type "Event Viewer"
Open the Event Viewer app
In the left pane, click on "Windows Logs" and then "Application"
Look for an event with the source "Wininit" and event ID 1001
Double-click on the event to view the details, including information about any errors found and corrected by CHKDSK.

Step 4: Diagnose memory

To perform a memory diagnostic test on a Windows computer, follow these steps:

Press the Windows key + R to open the Run dialog box.
Type "mdsched.exe" and press Enter.
Select whether you want to restart your computer and run the test immediately or schedule the test for the next time you restart your computer.
The test may take several minutes to complete, and your computer may appear to be unresponsive during this time.
After the test is complete, your computer will restart and return to the Windows desktop.
You can view the results of the test by opening the Event Viewer.

Alternatively, consider using third-party memory diagnostic tools like Windows Memory Diagnostic, Memtest86, or Memtest86+.

Note: Two Anti-virus is not better than one!

More than one antivirus will cause conflict and system instability. Remove them all and stick with inbuilt security for simplicity.

Remove malware and crapware

Keeping third party software to a minimum helps reduce potential complications. Consider removing software that is no longer required.
