CMD and PowerShell are not opening

Question

I have a problem with either CMD and PowerShell. Recently when I try to open any of them, a blank window is shown for a few seconds, then closes. I tried also to open as an administrator, it opens directly without the Security Warning message, also blank and closes after a few seconds. I am running on Windows 11 Pro, and have only Windows Defender as an antivirus. I went om safe mode and run CMD, it opened without a problem. I run sfc /scannow , it found and fixed some problems. After I restarted into normal mode and tried to open any of CMD or PowerShell again, still blank window then closes automatically. Please help me.

Hello,

Thank you for posting in Q&A forum.

The problem you are experiencing may be caused by system file corruption or other software conflicts. Here are some possible solutions:

Run the DISM tool: Open a command prompt (with administrator privileges) and run the following command: DISM/Online/Cleanup Image/RestoreHealth. This will scan and repair any damage in the system image.

Re register CMD and PowerShell: Run the following command from the command prompt or PowerShell: sfc/scannow. This will scan system files and attempt to repair any damaged files.

Check for third-party software conflicts: Temporarily disable all third-party antivirus and security software, and try reopening CMD or PowerShell. If the problem is resolved, enable third-party software one by one to determine if there are any conflicts related to it.

Create a new user account: Create a new local user account and try logging in and opening CMD or PowerShell using that account to see if the same problem still occurs.

System Restore: If none of the above methods are effective, you can try using System Restore to restore the system to a state where there were no issues before.

Hope this answer can help you well.
