If all goes according to early plans, Threshold will include updates to all three OS platforms (Xbox One, Windows and Windows Phone) that will advance them in a way to share even more common elements.
(The codename Threshold, for those wondering, derives from the planet around which the first halo ring orbited in the original Halo game launched back in 2001. Threshold joins "Cortana," Microsoft's answer to Siri, as yet another codename with its origins in the Xbox franchise.)
From what I've heard, Threshold doesn't refer to a single Windows OS -- not even the expected, converged hybrid comprised of the Windows Phone OS and Windows RT. Instead, the codename refers to the wave of operating systems across Windows-based phones, devices and gaming consoles.
BTW When I use Windows 8 (in parallels) I used a few applications to make it more comfortable for me such as:
https://www.stardock...ucts/modernmix/ This allows you to optionally put metro apps into a window or full screen as you wish.
https://www.stardock...roducts/start8/ To have a Windows 7 or below style start menu
https://www.stardock...s/windowblinds/ to have any kind of UI theme I want including Mac style ones...
I used to use a Mac style menubar app (and Dock) in Windows XP but it doesn't work so well in 8 so I've been sticking to the task bar and start menu instead. I could probably still use the dock apps for Windows but they'd be redundant with the task bar.
