Using [Alt]+[Prnt Scrn] to capture or copy & paste an active window instead of the whole screen
In case anyone has not yet learnt this nifty little trick within MS Windows..
I find it very useful in the documentation I create, or for adding images to things like emails, etc. It makes referring to things so much easier when a picture of only the most relevant window is what is needed. A picture of the whole desktop can distract from what you are specifically trying to point out.. or for various other reasons.
Normally to capture a copy of your whole desktop screen, press the [Prnt Scrn] button and then in whatever application you want to paste that image, like MS Word for instance, simply use:
Edit -> Paste
or use the short-cut key sequence on your keyboard:
[Ctrl]+[V]
So now all you do to capture only the currently highlighted / active window (instead of the whole desktop) is:
[Alt]+[Prnt Scrn]
and in the target word / email / whatever app:
Edit -> Paste
or use the short-cut key sequence on your keyboard:
[Ctrl]+[V]
Voila.
