Repairing Windows 10 using Command Prompt can seem daunting, but it’s actually pretty straightforward once you get the hang of it. This guide will walk you through each step, helping you fix issues and get your system running smoothly again. Stick around, and we’ll make sure your Windows 10 is back in top form in no time!
Step by Step Tutorial on How to Repair Windows 10 using Command Prompt
In this tutorial, we’ll cover several commands you can use to repair your Windows 10 installation. From checking system files to fixing boot issues, these steps will have your PC up and running.
Step 1: Open Command Prompt as Administrator
Press Win + X, then select "Command Prompt (Admin)" or "Windows PowerShell (Admin)".
Opening Command Prompt as an administrator gives you the necessary permissions to run repair commands. If you don’t have admin rights, some commands won’t execute properly.
Step 2: Run System File Checker (SFC)
Type sfc /scannow and press Enter.
The System File Checker scans and repairs corrupt system files. This process might take some time, but it’s worth the wait. If it finds any issues, it will attempt to fix them automatically.
Step 3: Use Deployment Imaging Service and Management Tool (DISM)
Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
DISM can repair the Windows image itself. This command checks for component store corruption and restores good health to your system image, which is essential if SFC couldn’t fix everything.
Step 4: Check Disk for Errors
Type chkdsk /f /r and press Enter. When prompted, type Y to schedule the check on the next restart.
Check Disk (chkdsk) looks for and fixes disk errors. Scheduling it for the next restart ensures that it runs without interference from other programs.
Step 5: Repair the Boot Configuration Data (BCD)
Type bootrec /fixmbr, bootrec /fixboot, and bootrec /rebuildbcd, pressing Enter after each command.
These commands fix common boot issues by repairing the Master Boot Record (MBR) and rebuilding the Boot Configuration Data (BCD). If your PC struggles to start, this should help.
After completing these steps, your Windows 10 system should be in better shape. The repairs might take some time, but they can resolve many common issues.
