MS 2 nightly under Windows 10
I realize that Windows 10 is still months away but in case anyone else is daring enough to try the preview released in early October, my tests of one of the later nightly builds of 2.0 seems to work fine. Of course, it's still basically Windows 8 under the hood, and MuseScore 1.3 works fine with Win8.x.
With the removal of the Start Screen and charms, the re-integration/re-design of the Start Menu, and apps being in resizable windows, it finally feels like normal Windows again. Looking forward to the full release of both of these!
