Repairing a PC using the command prompt (cmd) can be a useful troubleshooting technique if you're encountering software-related issues. Here's a step-by-step guide on how to perform basic repairs using cmd:
1. Open the Command Prompt: Press the Windows key + R to open the Run dialog box. Type "cmd" and press Enter to open the command prompt.
2. Run System File Checker (SFC) Scan: Type "sfc /scannow" in the command prompt and press Enter. This command verifies the integrity of system files and repairs any corrupt files it finds. It may take some time to complete the scan.
3. Run Deployment Image Servicing and Management (DISM) Tool (optional): If the SFC scan doesn't fix the issue, you can try running the DISM tool to repair the system image. Type "DISM /Online /Cleanup-Image /RestoreHealth" in the command prompt and press Enter. Allow the process to complete. Note that this command requires an internet connection to download any necessary files.
4. Check Disk for Errors: Type "chkdsk C: /f" in the command prompt and press Enter. Replace "C:" with the drive letter where your operating system is installed, if different. This command will check the disk for errors and attempt to fix them.
5. Restore System Files: If you suspect that a specific system file is causing the issue, you can use the "sfc /restorehealth" command to repair system files using the Windows Update service. Type "sfc /restorehealth" in the command prompt and press Enter.
6. Restart Your PC: After completing the repairs, it's a good idea to restart your computer to allow the changes to take effect.
Note that these steps are intended for basic repairs and may not fix complex hardware or major software issues. Additionally, it's important to create a backup of your important files before attempting any repairs.
Remember, when performing repairs using cmd, it's crucial to follow instructions carefully and ensure that you have a backup plan in case anything goes wrong. If you're unsure or uncomfortable with using the command prompt, it's always advisable to seek professional assistance from an experienced technician.
