Up and running. Took a while to download and then more time to tweak (their word, not mine).
I disabled all the apps upon installation (no, Microsoft, don't need you to know what all I'm doing) and am not planning to use Edge since it currently doesn't allow extensions such as the one that rhymes with SadRock.
Now to adjust the annoying, new notification sounds. Seems as if that's more complicated than it needs to be.
Do not miss those annoying rolling windows from 8.1 at all!! BIG STEP forward already, imho.
