How to update PowerShell engine?

Question

Hello!

I'm trying to update the PowerShell engine using the update-help command and nothing happens as it's still on version 2.0. I want to upgrade to 3.0. My PC has Windows 10 Pro 64-bit.

Answer 1

"MicrosoftWindowsPowerShellV2Root" and "MicrosoftWindowsPowerShellV2" feature names are left for compatibility between Windows versions upgrades

Powershell version itself is updated per OS

Answer 2

The "Update-Help" won't do anything more than update the help files for the installed version of Powershell and modules.

It's common for Update-Help to encounter errors. The XML file may contain a bad link. There may not be a help file for the UI culture.

If you want to update the help for as many modules as possible, run it like this:

Update-Help -Force -ErrorAction SilentlyContinue -ErrorVariable ErrorMsgs

You won't see any errors while it's running, but you can use $ErrorMsgs.Exception to see the modules that had failed updates.

PowerShell itself should already be installed on Windows 10. The check, run PowerShell and execute $PSVersionTable. You should see something like this:
