Windows PowerShell Has Stopped Working [Solved]

Windows PowerShell is a robust tool for system administrators and advanced users to manage and automate tasks in Windows. However, sometimes it might stop working unexpectedly, which can cause frustration. You may encounter an error message like "Windows PowerShell has stopped working" when trying to launch or use the tool. This can be due to several reasons such as system file corruption, conflicts with other software, or issues with your configuration settings. In this blog, we’ll guide you through several troubleshooting methods to fix PowerShell when it stops working, helping you get back to using this powerful tool without interruption.

What Causes PowerShell to Stop Working?

PowerShell may stop working due to several potential causes, including system file corruption, outdated software, or third-party software conflicts. When essential system files related to PowerShell are damaged or missing, it can cause the tool to malfunction. Additionally, antivirus software or third-party security tools might block PowerShell from running due to security settings. Sometimes, incorrect configurations or settings in PowerShell can also prevent it from opening or working correctly. Understanding the cause is the first step to solving the issue effectively.

Check for Windows Updates

Outdated Windows versions can cause compatibility issues with PowerShell, leading it to stop working. Microsoft frequently releases updates that fix bugs, improve performance, and resolve compatibility problems with various apps, including PowerShell. Make sure your system is up to date by checking for any pending Windows updates. To do this, open the Settings app, go to “Update & Security,” and click “Windows Update.” Install all available updates and restart your PC to see if PowerShell begins working again.

Run System File Checker (SFC)

Corrupt system files are a common cause of PowerShell failures. The System File Checker (SFC) tool scans for missing or corrupted system files and attempts to restore them. To run the SFC tool, open the Command Prompt as an administrator by typing "cmd" in the Start menu, right-clicking on it, and selecting "Run as administrator." Then type sfc /scannow and press Enter. This tool will scan your system and automatically fix any issues it detects, potentially resolving the PowerShell issue.

Use DISM to Repair System Image

If SFC doesn’t solve the problem, you can use the Deployment Imaging Service and Management Tool (DISM) to repair Windows system files. DISM is a more advanced tool that can fix issues with the system image that SFC may not be able to address. Open the Command Prompt as an administrator and type the following command: DISM /Online /Cleanup-Image /RestoreHealth. Press Enter, and DISM will scan and repair any problems with your system image. This can help resolve deeper system issues that prevent PowerShell from functioning.

Disable Antivirus or Security Software

At times, third-party antivirus software can block PowerShell from working, as it may mistake PowerShell’s actions as suspicious. To check if your antivirus is the culprit, temporarily disable it and see if PowerShell starts working again. Make sure to enable your antivirus software immediately after testing, as disabling it leaves your system vulnerable. You can also check your antivirus settings for any options that block or restrict PowerShell. If PowerShell works after disabling the antivirus, you may need to adjust the antivirus settings to allow PowerShell to run properly.

Reset PowerShell to Default Settings

Sometimes PowerShell may stop working due to configuration issues or changes made to its settings. If you’ve customized PowerShell settings and it’s not functioning properly, resetting PowerShell to its default settings may resolve the issue. Open the PowerShell window as an administrator and type the command Remove-Item -Path $PROFILE -Force. This will remove any personalized settings and restore PowerShell to its default configuration. After resetting, try opening PowerShell again to see if the issue persists.

Check for PowerShell Corruption

PowerShell itself can sometimes become corrupted, especially if there have been issues with updates or installation. If this happens, reinstalling or repairing PowerShell can often fix the problem. You can reinstall PowerShell by going to the “Optional Features” section of the Settings app and selecting PowerShell. Alternatively, you can use the Windows Features dialog to turn off PowerShell, restart your computer, and then turn it back on to reset its installation. This might help resolve any corruption issues preventing PowerShell from working properly.

Create a New User Profile

In some cases, PowerShell issues may be tied to your user profile, which might be corrupted. If other troubleshooting methods haven’t worked, try creating a new user profile to see if PowerShell works under that profile. Go to Settings, select “Accounts”, and click “Family & other users” to add a new account. After creating the new account, log in and check if PowerShell works correctly. If it does, your original user profile might be the issue, and you can transfer your data to the new profile.

Perform a System Restore

If PowerShell stopped working after a recent change, such as installing new software or updates, a system restore might fix the problem. System Restore allows you to revert your system to an earlier point in time when PowerShell was functioning properly. To perform a system restore, type “System Restore” into the search bar, open the tool, and follow the on-screen instructions to choose a restore point before the issue occurred. This process can undo any problematic changes and restore PowerShell to its working state.

Consider Reinstalling Windows

If none of the above solutions work and PowerShell is still not functioning, reinstalling Windows may be the last resort. Reinstalling Windows will fix any underlying issues that are preventing PowerShell from working correctly, but it will also erase your data, so make sure to back up your files first. To reinstall Windows, go to Settings, select “Update & Security,” and then choose “Recovery” to initiate the process. After reinstalling, PowerShell should work as expected, and you can restore your files from backup.

7 Steps to Fix PowerShell Not Working

1. Check for the latest Windows updates and install any pending updates.
2. Run System File Checker (SFC) to repair corrupted system files.
3. Use DISM to repair the Windows system image.
4. Temporarily disable antivirus software and check if PowerShell works.
5. Reset PowerShell settings to their default configuration.
6. Reinstall or repair PowerShell via Windows Features or Optional Features.
7. Perform a System Restore to revert to a previous working state.

7 Key Troubleshooting Tips for PowerShell Issues

1. Ensure your system has the latest updates installed.
2. Run SFC and DISM regularly to keep system files intact.
3. Always back up your data before making significant changes.
4. Check for conflicts with third-party software that may block PowerShell.
5. Create a new user profile if you suspect profile corruption.
