How to Repair Windows with CMD

When your Windows starts acting up – slow performance, frequent crashes, or even the dreaded Blue Screen of Death – something is wrong. However, remember that you have a powerful tool: the Command Prompt (CMD). 

This step-by-step guide will show you how to repair Windows using CMD commands. It will help you troubleshoot and resolve common issues.

Why Repair Windows 10 with CMD?

The Command Prompt is an application in most Windows operating systems. It provides direct access to the system’s internal settings and utilities, making it a valuable resource for repairing various issues. 

Using CMD commands for Windows repair can be particularly handy when graphical user interfaces are not accessible due to system instability.

  1. Type CMD into the Start Menu. In the Windows search bar, type “CMD.” Then, right-click “Command Prompt” and choose the option “Run as administrator.” This will let you access the Command Prompt with elevated privileges, allowing you to perform system-level changes.

With secured administrative access, you can start repairing your Windows system.

  1. Run the Command Prompt as an administrator.
  2. Type the following command and press Enter to check the health of the Windows image: dism /online /cleanup-image /checkhealth
