It make sense by default if you download 3rd party powershell packages like kbupdate, it should not run right away until you’ve done your due dilligence. You’ll get a warning like this during installation:

Untrusted repository
You are installing the modules from an untrusted repository. If you trust this repository, change its InstallationPolicy value by running the Set-PSRepository cmdlet. Are you sure you want to install the modules from 'PSGallery'?

But when I try to use it, I get an error message:

Get-KbUpdate : The 'Get-KbUpdate' command was found in the module 'kbupdate', but the module could not be loaded. For more information, run 'Import-Module kbupdate'.

Import-Module gives a cryptic message like this:

Import-Module : Errors occurred while loading the format data file:
D:\Administrator\Documents\WindowsPowerShell\Modules\PSFramework\1.6.214\xml\PSFramework.Format.ps1xml, ,
D:\Administrator\Documents\WindowsPowerShell\Modules\PSFramework\1.6.214\xml\PSFramework.Format.ps1xml: The file was
skipped because of the following validation exception: File
D:\Administrator\Documents\WindowsPowerShell\Modules\PSFramework\1.6.214\xml\PSFramework.Format.ps1xml cannot be
loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at

Turns out either the package needs to be marked safe or just stop checking altogether:

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
