Hi. :)
A thought:
The above error is common when you run the command from an elevated command prompt instead of PowerShell.
To make sure that you are in Powershell, write Powershell in the Search area, and then right click the item in the list to run it as administrator. It's a blue window, not black.
OK, so I had a misunderstanding, mistook command prompt for PowerShell.
Now I tried PowerShell in Admin mode.
Below a copy of the red text that appeared after pasting in the lines you suggested:
Get-Process : A positional parameter cannot be found that accepts argument 'Get-AppXPackage'.

I am not sure which one to use, coz three powershell entries show up in the search
Powershell
Powershell x 86
Powershell ISE
