How to Fix Windows 11 Problems Using Command Prompt

When Windows 11 starts acting up, the Command Prompt can be your secret weapon for diagnosing and fixing problems. This powerful tool allows you to run scans, repair system files, and even fix disk errors – often resolving issues without needing to reinstall Windows. Let’s explore how to leverage Command Prompt to get your Windows 11 system back in shape.

Accessing the Command Prompt as Administrator

Before we dive into repair techniques, it’s crucial to open Command Prompt with administrative privileges. This ensures you have the necessary permissions to make system-level changes.

Step 1: Press the Windows key and type “cmd”.

Step 2: Right-click on “Command Prompt” in the search results.

Step 3: Select “Run as administrator” from the context menu.

Step 4: Click “Yes” when prompted by User Account Control.

You’ll now see the Command Prompt window with a title that includes “Administrator”. This indicates you have the necessary privileges to run system repair commands.

Running System File Checker (SFC)

The System File Checker is a built-in Windows tool that scans for and repairs corrupted system files. It’s often the first line of defense against system instability.

Step 1: In the Command Prompt window, type the following command and press Enter:

sfc /scannow

Step 2: Wait for the scan to complete. This process can take several minutes.

Step 3: Once finished, you’ll see one of these messages:

  • “Windows Resource Protection did not find any integrity violations.” – No issues were found.
  • “Windows Resource Protection found corrupt files and successfully repaired them.” – Issues were found and fixed.
  • “Windows Resource Protection found corrupt files but was unable to fix some of them.” – Some issues require further action.

If SFC couldn’t fix all the problems, proceed to the next method.

Using DISM to Repair Windows Image

The Deployment Image Servicing and Management (DISM) tool can repair the Windows image, which may resolve issues that SFC couldn’t fix.

Step 1: In the Command Prompt, type this command and press Enter:

DISM /Online /Cleanup-Image /RestoreHealth

Step 2: Allow the process to complete. This can take 15-30 minutes or longer.

Step 3: Once DISM finishes, restart your computer.

Step 4: After restarting, run the SFC scan again to ensure all issues are resolved.

Checking and Repairing Disk Errors

Disk errors can cause various system problems. The Check Disk utility (CHKDSK) scans for and repairs file system errors and bad sectors on your hard drive.

Step 1: In the Command Prompt, type the following command and press Enter:

chkdsk /f /r

Step 2: If prompted to schedule the scan for the next restart, type “Y” and press Enter.

Step 3: Restart your computer to run the scheduled scan.

The “/f” parameter fixes errors on the disk, while “/r” locates bad sectors and recovers readable information.

Repairing Boot Problems

If Windows 11 won’t start properly, you can use the Bootrec.exe tool to repair the Master Boot Record (MBR), boot sector, or Boot Configuration Data (BCD).

Step 1: Boot from a Windows 11 installation media or recovery drive.

Step 2: Select “Repair your computer” when prompted.

Step 3: Choose Troubleshoot > Advanced options > Command Prompt.

Step 4: Run these commands in order, pressing Enter after each:

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

Step 5: After running these commands, type “exit” and press Enter to close Command Prompt.

Step 6: Restart your computer and check if the boot issues are resolved.

Tips for Effective Command Prompt Repairs

  • Always back up important data before performing system repairs.
  • Ensure your computer is plugged in to prevent interruptions during lengthy scans.
  • If a command doesn’t work, try rebooting and running it again.
  • For persistent issues, consider using Windows 11’s built-in “Reset this PC” feature as a last resort.

Command Prompt might seem intimidating at first, but it’s a powerful ally in maintaining your Windows 11 system. By mastering these repair techniques, you can often resolve issues quickly without resorting to a full reinstall. Remember, if you’re unsure about any step, it’s always wise to consult with a professional or Microsoft support for guidance.
