How to install Microsoft Windows Terminal

Installing it straight from the Microsoft Store didn't work for me either. In Windows 10 1909, I did (it's an msix). Note that the appx commands are gone in powershell 7.1.

Add-AppxPackage Microsoft.WindowsTerminal_0.11.1191.0_8wekyb3d8bbwe.msixbundle

and it installed ok.

get-appxpackage microsoft.windowsterminal
