The win+pageUp or pageDown to move the metro between 2 screens no longer works. I can't grab the metro with the mouse and drag it to the other screen anymore as well.
When windows 8 starts up i get the metro on first screen but second screen is a blank solid color no more taskbar desktop, i have to hit desktop tile to get both desktop taskbar on both screens, and then i can get metro on one screen and taskbar on second.
When installing applications for the first time windows no longer automatically pins the main program to the metro you have to scroll down on second page of metro and look through all that mess to find your program and pin it to the 1st page metro.
I can't pin my shutdown and restart shortcuts to the metro anymore. The metro side scrolling with the mouse is sluggish compared to windows 8.
Labels in the metro are nice but haven't found a way yet to change the font's size, color, type. But, I think i have seen this option somewhere not 100% sure.
I kind of understand it now how people perceive windows 8 and 8.1 to be schizophrenic, we only need one GUI, but people should have the option to choose between the old start menu and the full metro gui.
The metro has to extend to the second or third monitor. It has to open any desktop applications in front of it. The left side corner is basically a taskbar anyway and should manage the old desktop apps as well.
I think it's going to be a long way before this type of OS matures and one of these GUI's will win the battle.
