Please explain the bug

When I try to run the commands, powershell gives the following error: Get-MpComputerStatus: Invalid Class

Hi, That looks like your system has a problem running one of the built-in cmdlets: Get-MpComputerStatus Try running just that and let me know what you see.

I just released an update. It reduces the number of times the built-in Get-MpComputerStatus cmdlet is called. Although the issue you have must be unrelated to the hardening module but still the script uses that cmdlet more intelligently and it makes things faster.

I tried runnin only "Get-MpComputerStatus" and got the same error: Get-MpComputerStatus: Invalid Class

Now after the update, the following error: Get-MpComputerStatus: Invalid Class Get-MpPreference: Invalid Class Add-MpPreference: Invalid Class Add-MpPreference: Invalid Class Add-MpPreference: Invalid Class

I think my system is not totally compatible with this tool, it's not your fault. Besides that, there's something wrong with secure boot, I don't know why, but powershell thinks I don't have it enabled. This tool only works with UEFI???

[HotCakeX]

Try uninstalling PowerShell and reinstall it again, maybe from store, if that doesn't fix it then the problem might be deeper.

These cmdlets should show if secure boot is enabled or not Confirm-SecureBootUEFI Get-SecureBootPolicy

The script doesn't check for UEFI specifically. What is your hardware specs?

Looks like you're using the old PowerShell Please run this command to install the new one

Winget install Microsoft.PowerShell

@kelvinkad Hi, I just pushed a new update that automatically takes care of everything for you. You can read more about it here: https://github.com/HotCakeX/Harden-Windows-Security/pull/263

[kelvinkad]

Thank you very much for that. Now the errors are very few, but don't worry, I'll try to fix it somehow, or maybe my system is not compatible with requirements of your tool.

The actual errors are:

Get-MpComputerStatus: Invalid class
Get-MpPreference: Invalid class
Add-MpPreference: Invalid class
Add-MpPreference: Invalid class
Add-MpPreference: Invalid class
Confirm-SecureBootUEFI:
