Practical Solutions to Stop CMD Keeps Popping Up on Your Screen

Scanning and Cleaning Malware

To scan and clean malware in Windows 11, you can follow these steps:

1. Backup Important Data:
   • Before starting the scanning process, make sure to back up your important data to an external storage medium or cloud service.
2. Disconnect the Internet:
   • Disconnect the internet connection to prevent malware from communicating with external servers during the cleaning process.
3. Enter Safe Mode:
   • Restart your computer and enter Safe Mode. This will limit what’s running on your computer, which can help remove malware.
4. Delete Temporary Files:
   • Before performing a scan, delete all temporary files. This can help speed up the scanning process and remove some malware.
5. Use Windows Security to Scan:
   • Open Windows Security (formerly known as Windows Defender).
   • Select Virus & threat protection.
   • Under Current threats, select Scan options.
   • Select Windows Defender Offline scan, then click Scan now.
6. Use Anti-Malware Software:
   • Run trusted anti-malware software to scan and clean any threats found.
7. Remove Unknown Software:
   • Check the list of installed programs and remove software that is unknown or that you do not remember installing.
8. Browser Reset:
   • If your browser exhibits unusual behavior, perform a reset to remove any suspicious extensions or plugins.

Once the scanning and cleaning process is complete, restart your computer and check if the self-recurring CMD issue is resolved. If the problem persists, there may be other causes that need to be addressed, or you may need professional help.

Repairing Corrupted System Files

To fix corrupted system files in Windows 11, you can follow these steps:

1. Run the DISM command:
   • Open Command Prompt as Administrator by typing cmd in the search box, right-click on Command Prompt, and select ‘Run as administrator.
   • Type the following command and press Enter:
   • DISM.exe /Online /Cleanup-image /Restorehealth
   • Wait for the process to complete. This may take a few minutes.
2. Run the SFC command:
   • When DISM is complete, type the following command and press Enter:
   • sfc /scannow
   • This command will scan all protected system files and replace the corrupted files with the correct copy that resides in the compressed folder in %WinDir%\System32\dllcache.
3. Restart the computer:
   • After the SFC scan is complete, restart your computer to apply the changes.

The DISM command uses Windows Update to provide the files needed to repair the damage. If your Windows Update client is corrupted, you may need to use another repair source, such as Windows installation media.

If after executing both commands the problem persists, there may be more serious damage that requires further action, such as system restore or reinstallation of Windows.

Prevention so that CMD does not appear again

To prevent Command Prompt (CMD) from popping up unexpectedly in Windows 11, you can take the following precautions:

1. Regular Updates: Make sure your operating system and all software are always up to date with the latest version. These updates often include security fixes that may prevent CMD issues from occurring on their own.
2. Task Scheduler Settings: Check the Task Scheduler periodically to make sure no suspicious or unnecessary tasks are scheduled to run automatically.
3. Antivirus Protection: Use a strong antivirus solution and make sure it is always updated. Run regular scans to detect and remove any malware or viruses that might be causing CMD to appear.
4. Startup Management: Manage programs run at startup through Task Manager and disable unnecessary or suspicious applications.
5. Use of Restricted Accounts: Use accounts with limited access rights for daily activities and avoid using administrator accounts unless necessary.
6. Data Backup: Make regular data backups to prevent losing important information in case of malware infection or system crash.
7. User Education: Educate yourself about the latest security threats and best practices for keeping your computer secure.

By following these preventive measures, you can reduce the risk of CMD popping up suddenly and keep your system safe and stable.
