Repair System Files

Fix Windows Corruption is the core system integrity repair that restores corrupted Windows components using Microsoft's own repair tools. It runs a multi-stage pipeline: first DISM (Deployment Image Servicing and Management) downloads fresh copies of damaged system files from Windows Update, then SFC (System File Checker) verifies and replaces corrupted protected files. This repair fixes the root cause of blue screens, update failures, and application crashes caused by system file damage. It creates a restore point before starting and provides a detailed log. Takes 5-15 minutes depending on the extent of corruption.
