Fix and Repair Windows 11 Using DISM and SFC Commands (Complete Script)
If your Windows 11 PC is slow, freezing, or showing errors, it might have corrupted system files. The easiest way to fix this without reinstalling Windows is to use DISM (Deployment Image Servicing and Management) and SFC (System File Checker) together.
Here’s a single, combined script that performs all checks, scans, and repairs automatically — step by step.
Full Repair Script (Run as Administrator)
Copy and paste this entire script into Command Prompt (Admin) or PowerShell (Admin):
