Thanks to folks from Microsoft, MSIX Hero is also available in the repository of winget packages (https://github.com/microsoft/winget-pkgs/tree/master/manifests/MarcinOtorowski/MSIXHero). This means that installing MSIX Hero is now even easier than before, provided that you have a winget client installed.
If you haven’t tried it yet, I highly recommend getting it now for testing and previewing of how the official Windows package manager works. You can get the client from the following URL:
https://github.com/microsoft/winget-cli/releases
And then discover and install apps using a few basic commands (type winget to see help). For example, this is how you install MSIX Hero (the newest version) using exactly 24 key strokes:
winget install msixhero
Have fun with testing!
