FIX Windows PowerShell has Stopped Working

Encountering the error "Windows PowerShell has stopped working" can be frustrating, especially when you rely on PowerShell for system administration tasks and automation in Windows. This error typically indicates a problem with the PowerShell environment or a conflict with other software or system components. Resolving this issue involves troubleshooting steps such as checking for system updates, repairing PowerShell components, examining module conflicts, and ensuring system integrity through various diagnostic tools. By systematically addressing the underlying causes, you can restore PowerShell functionality and continue using it effectively for your tasks.

Verify System and PowerShell Updates

Check for Windows Updates

Ensure your Windows operating system is up to date, as updates often include patches and fixes for system components including PowerShell:

1. Open Settings: Go to Settings > Update & Security > Windows Update.
2. Check for Updates: Click on "Check for updates" and install any available updates for Windows.

Restart your computer after installing updates to apply changes and verify if the PowerShell error persists.

Update PowerShell Version

If using an older version of PowerShell, consider updating to the latest version:

1. Download PowerShell Core: Visit the official PowerShell GitHub repository or Microsoft’s website to download the latest version of PowerShell Core.
2. Installation: Follow the installation instructions to upgrade PowerShell to the latest version compatible with your operating system.

Newer versions often include performance improvements and bug fixes that can resolve issues causing PowerShell to stop working.

Repair PowerShell Components

Run PowerShell as Administrator

Running PowerShell with administrative privileges can help resolve permissions-related issues:

1. Search for PowerShell: Type "PowerShell" in the Windows search bar, right-click on Windows PowerShell, and select "Run as administrator."
2. Execute Commands: If PowerShell opens successfully, run commands such as Get-ExecutionPolicy to verify execution policies and Get-Command -Module Microsoft.PowerShell.Core to check core module status.

Repair PowerShell Installation

If PowerShell continues to malfunction, repair its installation to fix corrupted or missing files:

1. Open Control Panel: Go to Control Panel > Programs > Programs and Features.
2. Select PowerShell: Right-click on Windows PowerShell and choose "Repair" or "Modify" to repair the installation.

Follow on-screen instructions to complete the repair process and restart your computer afterward.

Check for Module Conflicts

Disable Problematic Modules

Conflicting PowerShell modules can cause errors. Temporarily disable third-party or custom modules to identify if they are causing PowerShell to stop working:

1. Open PowerShell: Launch PowerShell as administrator.
2. Check Installed Modules: Run Get-Module -ListAvailable to list installed modules.
3. Disable Modules: Use Remove-Module -Name <ModuleName> or Disable-PSRemoting -Force to disable modules suspected of causing conflicts.

Test PowerShell functionality after disabling modules to determine if the error persists.

Verify System Integrity

Run System File Checker (SFC)

Use the System File Checker (SFC) tool to scan and repair corrupted or missing system files:

1. Open Command Prompt: Type "cmd" in the Windows search bar, right-click Command Prompt, and select "Run as administrator."
2. Run SFC Scan: Enter sfc /scannow and press Enter to initiate the scan.
3. Review Results: After the scan completes, review the results to see if any issues were found and fixed.

Restart your computer after running SFC to apply repairs and check if PowerShell functions correctly.

Use DISM Tool

If SFC does not resolve system file issues, use the Deployment Imaging Service and Management (DISM) tool:

1. Open Command Prompt: Run Command Prompt as administrator.
2. Run DISM Command: Enter DISM /Online /Cleanup-Image /RestoreHealth and press Enter to repair the Windows image using files from the Windows Update.

DISM repairs can take some time to complete. Restart your computer afterward and test PowerShell functionality.

Address Environment Variables and Permissions

Check Environment Variables

Incorrect or missing environment variables can affect PowerShell’s operation. Verify environment variables are correctly configured:

1. Open Control Panel: Go to Control Panel > System and Security > System.
2. Advanced System Settings: Click on "Advanced system settings" on the left.
3. Environment Variables: Under the Advanced tab, click on "Environment Variables" and review variables like Path.

Ensure PowerShell-related paths are included in the system’s Path variable to access necessary executable files.

Adjust Execution Policies

Execution policies control script execution in PowerShell. Adjust policies if they are too restrictive:

1. Open PowerShell: Launch PowerShell as administrator.
2. Set Execution Policy: Run Set-ExecutionPolicy RemoteSigned or Set-ExecutionPolicy Unrestricted to adjust execution policies temporarily.

Be cautious when adjusting execution policies, as they affect system security.

Reinstall or Restore PowerShell

Reinstall PowerShell

If troubleshooting steps fail to resolve the issue, consider reinstalling PowerShell:

1. Uninstall PowerShell: Go to Control Panel > Programs > Programs and Features, right-click Windows PowerShell, and select "Uninstall."
2. Reinstall PowerShell: Download the latest version of PowerShell from Microsoft’s website or re-enable it through Control Panel.

Follow installation instructions to reinstall PowerShell and test functionality afterward.

Restore PowerShell Defaults

Restoring PowerShell to default settings can resolve persistent issues:

1. Open PowerShell: Launch PowerShell as administrator.
2. Reset to Defaults: Run Get-Module -ListAvailable | Remove-Module to remove all modules and Clear-Host to clear the PowerShell session.

Restart PowerShell and verify if the error persists.

Summary

Resolving "Windows PowerShell has stopped working" errors requires a systematic approach to identify and address underlying causes such as system updates, module conflicts, corrupted files, or environment variables. By following these troubleshooting steps, you can restore PowerShell functionality and continue using it effectively for system administration tasks and automation in Windows. Regular maintenance and updates help ensure PowerShell operates reliably, enhancing productivity and system management capabilities on your computer.
