As a fairly clueless Windows user (I've spent most of my life using "real" OS's.) I'd like to ask you the best way to generate those PNG dumps of regions of your desktop or screen such as you have shown above.

I know there are lots of little "snapshot" type utils for *nix, and some long-ago macs
would dump a screen bitmap to disk at a certain keystroke (I assume they still do
but I don't know).

Anyway, I poked around on my Windows machine and looked through the wonderfully useless help utility, but to no avail.

I assume there is a well-known keystroke or utility that will dump the entire screen, or let me select a rectangle for the clipboard. Someone please enlighten me as to how this is accomplished in the Gates and Ballmer universe.

Thanks,
