Messed up Windows .ps1 file, and now can't open CMD or run any commands in Powershell

If you have recently messed up a Windows .ps1 file and are now unable to open Command Prompt (CMD) or run any commands in PowerShell, don't worry! We understand that this can be frustrating, especially if you are new to using these tools. In this article, we will guide you through some steps to help you resolve this issue and regain access to CMD and PowerShell.

Step 1: Check for Errors in the .ps1 File

The first thing you should do is check the .ps1 file that you modified or created. It is possible that there is an error in the file that is causing the issue. Open the file in a text editor and carefully review the code for any syntax errors or typos. Make sure all the brackets, parentheses, and quotation marks are properly closed. Correct any errors you find and save the file.

Step 2: Reset PowerShell to Default Settings

If you are still unable to open CMD or run commands in PowerShell, it may be necessary to reset PowerShell to its default settings. To do this, follow these steps:

1. Press the Windows key + X on your keyboard and select "Windows PowerShell (Admin)" from the menu. This will open PowerShell with administrative privileges.
2. In the PowerShell window, type the following command and press Enter: Set-ExecutionPolicy Restricted
3. You will be prompted to confirm the change. Type Y and press Enter.
4. Close PowerShell and restart your computer.

Step 3: Run System File Checker

If the issue persists, running the System File Checker (SFC) tool may help resolve any corrupted or missing system files that could be causing the problem. Follow these steps:

1. Press the Windows key on your keyboard and type "cmd".
2. Right-click on "Command Prompt" in the search results and select "Run as administrator".
3. In the Command Prompt window, type the following command and press Enter: sfc /scannow
4. The SFC tool will now scan your system files and repair any issues it finds. This process may take some time.
5. Once the scan is complete, restart your computer.

After following these steps, you should be able to open CMD and run commands in PowerShell without any issues. If the problem persists, we recommend seeking further assistance from a professional or contacting Microsoft support.
