Strangely, one of the most useful things about OSX was the screenshot capability.
CMD+SHIFT+3 takes the whole screen to the desktop.
CMD+SHIFT+4 takes a selection to the desktop
CTRL+CMD+SHIFT+4 takes a selection to the clipboard.
Well, in windows 7 you can pretty much get most of that functionality by right clicking on the “Snipping Tool”, and assigning a hotkey to it. I made it CTRL+SHIFT+4.
It also saves to the clipboard for easy photoshop pasting available via the options dropdown in snipping tool.
