@lonetiger, I take it you've never had to support software installs on
shared machines, or students' machines where you can't be too sure of the
The reasons against using powershell and curl (or equiv) I would have
thought are pretty obvious:
you don't know what you're getting/what it might be downloading.
You might mis-type some command and cause havoc on your machine or on your
With Hugs you download the packed-up .exe; you disconnect from the internet
and run virus checks; you run the install while your machine is still in
quarantine. With Hugs install you (usually) don't need to go into Admin
Just because some long-winded process is "completely standard on Windows",
doesn't mean it's fit for use.
That's a general learning about stuff from Microsoft.

It’s understandable that you may not know it since your primary
platform isn’t Windows. But it’s been included in every single Windows
version for the past 13 years.

That scary looking command is nothing but a curl command allowing the
one time execution of a script from a remote source. As in a script
that’s not physically on your machine.
