How do i disable transparency for any given window (not for all) in Windows Vista/7? My goal is to take screenshot of window without background being visible through glass borders.

I don't think that's possible. What you can do is open another window or two (or three or four) and resize them to the same width and drag it underneath the window you want to have opaque.
