I can't really explain it, cause my keyword lead me to Alt+Space+M.
It's different because the way it works just different.
In Ubuntu, You can Hold down ALT Button and drag a window whenever you want to go. (This kind of ability I want to talk about)
Why I am asking this? I encountered some installer like AutoCAD, even with full resolution of my laptop (1920x1080) The window still show 90% of it, which is bad because the important button are on the bottom like [Next] [Cancel] [Install] [Finish], etc. I tried to drag it to the top, but Windows 7 won't let me do that.
Also, the installation screen doesn't have ability to Maximize.
