.SYNOPSIS
If you don't like the 'Bing' Button that Edge wants to display, you can use this script to turn it off.

.NOTE
Ultimately, we are just setting a registry entry. You can also do this via Active Directory policies (and a couple of other ways).

There is another, per-user rather than whole-machine, registry entry that you can set. (This is per a thread on Reddit, but I did
not bookmark that thread and I don't have time to search for it now...)
