I have installed the "enterprise evaluation" version, and think this will be a total disaster if deployed in its current form,
I can find no way to be no way to go to desktop by default
on the start screen you cannot grab and drag to move along, to navigate the start screen you can: move the mouse to the edge of the screen. use the mouse wheel to go left or right or use the scroll bar at the bottom
logging on with one of our test staff accounts the applications cover 10 screens, and sometimes it will not let me get to desktop.
when you log off or start the PC it brings up a "Lock screen" then when released it gives you too options log-on to the previous account or to another account, consequently it requires 2 clicks of the mouse before you can even start to enter your password, this is unchanged after joining the domain
most of the functions I use daily ("my computer", "command prompt" notepad, paint, remote desktop, shutdown, restart) have been hidden, and the only way to find them is to start typing, I can live with this but the average student or teacher (some of whom do not understand that a PC only works after it is turned on at the wall) will be unable to adjust.
the only solution I have been able to come up with to allow staff and students to find programs without starting typing would be to have folders on the desktop to categorize programs, making them possible to find.
the Windows operating system was named for the feature of being able to have applications open in "windows", which you could re-size and arrange how you wanted, this has remained in the "desktop" but gone from he new style applications(I understand we are not allowed to call them metro anymore), therefore Windows 8's new experience means it is technically no longer a "windows" operating system
this seems more like a devolution back to early Windows infrastructures were you had to keep entering and exiting Windows, I think it should be named for its experience on desktops, which is more like windows 3.x/DOS, I therefore I propose it be renamed Windows 7.1/MSIOS (MicroSoft Internet Opperating System, unfortunately IOS is taken).
I always have frequently worked in command line so while disorientating, I would be able to live with this OS for home use, I just think is is unsuitable for the school environment without a lot of refinement
