Here are all the main methods to force Windows 11 integrity checks and system repairs:

Method	Command / Steps	What It Does
SFC (System File Checker)	`sfc /scannow`	Scans and repairs protected system files using cached copies from `%WinDir%\System32\dllcache`
DISM Online Repair	`DISM /Online /Cleanup-Image /RestoreHealth`	Repairs the Windows image using Windows Update as source
DISM with Source	`DISM /Online /Cleanup-Image /RestoreHealth /Source:D:\Sources\install.wim`	Repairs using a local WIM/ESD file (useful when offline or WU unavailable)
DISM CheckHealth	`DISM /Online /Cleanup-Image /CheckHealth`	Quick check if image is flagged as corrupted (no repair)
DISM ScanHealth	`DISM /Online /Cleanup-Image /ScanHealth`	Deeper scan for component store corruption (no repair)
chkdsk	`chkdsk C: /f /r /x`	Checks file system integrity and repairs logical errors, recovers bad sectors
Startup Repair	Settings → Recovery → Advanced startup → Troubleshoot → Startup Repair	Fixes boot-related issues automatically
Reset with Keep Files	Settings → System → Recovery → Reset this PC → Keep my files	Reinstalls Windows while preserving user data
In-place Upgrade	Run `setup.exe` from mounted Windows 11 ISO	Full repair install preserving apps, settings, and files
WinRE Command Prompt	Boot to recovery → Troubleshoot → Command Prompt, then run SFC/DISM	Repairs when Windows won’t boot normally

Recommended sequence for thorough repair:

Pro tips:

Always run Command Prompt or PowerShell as Administrator
Check logs at %WinDir%\Logs\CBS\CBS.log for SFC details and %WinDir%\Logs\DISM\dism.log for DISM
If DISM fails to download repair files, use the /Source parameter with a matching Windows 11 ISO
For offline repairs (won’t boot), use /Image:C:\ and /ScratchDir parameters with DISM from WinRE
