2. Type “cmd” and press Enter to open a regular Command Prompt.
3. Type “cd\” and press Enter to navigate to the root of the C: drive.
4. Type “cd windows\system32” and press Enter to navigate to the System32 folder.
5. Type “cmd” and press Ctrl + Shift + Enter to open an elevated Command Prompt.
Once you have opened an elevated Command Prompt, you can use various commands to fix Windows errors. Some commonly used commands include:
– “sfc /scannow” – This command scans and repairs system files using Windows Resource Protection.
– “chkdsk” – This command checks and repairs file system errors on a specified drive.
– “dism /online /cleanup-image /restorehealth” – This command repairs the Windows image using Windows Update.
– “netsh winsock reset” – This command resets the Winsock catalog to fix network-related issues.
Run the System File Checker (SFC) Tool
To run the SFC tool, follow these steps:
1. Open the Command Prompt as an administrator. You can do this by pressing the Windows key + X and selecting “Command Prompt (Admin)” from the menu.
2. In the Command Prompt window, type sfc /scannow and press Enter. This command will start the scanning process.
3. Wait for the scanning process to complete. It may take some time, so be patient. The SFC tool will automatically repair any corrupted or missing system files it finds.
4. Once the scanning and repairing process is finished, you will see a message indicating whether any issues were found and fixed.
5. Restart your computer to apply the repairs.
Running the SFC tool can help resolve various Windows errors and improve your system’s stability. It is a useful troubleshooting step if you are experiencing issues with your Windows operating system.
Use DISM Command for Repair
If you’re experiencing Windows errors, the DISM (Deployment Image Servicing and Management) command can be a useful tool for repair. To use the DISM command, follow these steps:
1. Open the Command Prompt by pressing the Windows key + R, typing “cmd” in the Run dialog, and pressing Enter.
2. In the Command Prompt window, type “dism /online /cleanup-image /restorehealth” and press Enter. This command will scan your system for errors and attempt to repair them.
3. Wait for the command to complete its scan and repair process. This may take some time, so be patient.
4. Once the process is finished, restart your computer to see if the Windows errors have been resolved.
By using the DISM command, you can repair common Windows errors without the need for a boot disk or advanced technical knowledge. It’s a straightforward and effective way to fix issues with your operating system.
Note: It’s important to run the DISM command with administrative privileges. To do this, right-click on the Command Prompt icon and select “Run as administrator” from the context menu.
Remember to always backup your data before attempting any repairs or modifications to your system. If you’re unable to resolve the errors using the DISM command, you may need to consider other options such as restoring from a system restore point or seeking professional assistance.
Review SFC and DISM Results
Reviewing SFC and DISM Results is an essential step in fixing Windows errors using the Command Prompt.
To begin, open the Command Prompt by pressing the Windows key + R, typing “cmd”, and pressing Enter.
Firstly, run the System File Checker (SFC) by typing “sfc /scannow” and pressing Enter. This command will scan for and repair any corrupted system files.
After the scan is complete, you will see the results. If the scan found and fixed any issues, it will display a message stating so. If no issues were found or if the scan couldn’t repair some files, you may need to use the Deployment Image Servicing and Management (DISM) tool.
To run DISM, type “dism /online /cleanup-image /restorehealth” and press Enter. DISM will check for and restore any corrupted files using Windows Update. This process may take some time, so be patient.
Once the DISM scan is complete, review the results. If any issues were found and fixed, the tool will display a message stating so. If the scan couldn’t fix the issues, you may need to use additional troubleshooting methods or seek professional help.
It’s essential to review the SFC and DISM results carefully to ensure that any Windows errors are properly addressed. These steps can help resolve various issues, including system file corruption, software conflicts, and other errors that may affect the stability and performance of your Windows operating system.
Remember to save any important data before running these commands and consider creating a system restore point or backup to avoid any potential data loss.
