Repair a Corrupted Windows Installation

To repair a corrupted Windows installation via Command Prompt (CMD), run the DISM and SFC tools. First, launch CMD as an Administrator, then execute: DISM.exe /Online /Cleanup-Image /RestoreHealth followed by sfc /scannow to scan and replace broken system files. [1, 2, 3]

Essential Windows Repair Commands

Follow these command-line tools in order for the most effective system repair:

1. Check/Repair Windows Image (DISM)

The Deployment Image Servicing and Management (DISM) tool fixes the core Windows image that contains your system files. [1, 2, 3]

Command: DISM.exe /Online /Cleanup-Image /RestoreHealth
Note: This requires an active internet connection to download replacement files if your local image is corrupted. [1, 2, 3]

2. Scan and Repair System Files (SFC)

The System File Checker compares your current Windows files with a cached, healthy version and replaces anything that is corrupted. [1, 2]

Command: sfc /scannow
Note: Do not close the window until the verification reaches 100%. It is highly recommended to run this immediately after the DISM command finishes. [1, 2]

3. Scan and Fix Disk Errors (CHKDSK)

The Check Disk utility scans your hard drive or SSD for bad sectors and file system errors, correcting structural corruption. [1, 2]

Command: chkdsk C: /f /r
Note: Since the drive is currently in use by Windows, CMD will ask to schedule the scan for your next system restart. Type Y (Yes) and hit Enter to confirm. [1, 2]
