Screenshot of OS

[Jux]

How on earth do I take a screenshot of my OS???

Press Alt+ Print Screen, then paste it into a picture editing program.
Hope that makes sense.

That's presuming that it's a Windows based PC... If it's not say what you have (e.g. are you on a Mac) and someone can give the answer.

If its a mac, its Shift/Cmd/3 (no idea why but there you go!)

Thanks all. It's a PC btw, but good to know how to do it with a Mac as we have a couple of those too. I needed it as the Product Key doesn't work for some software from software4students. Not sure what it's going to tell them though.
