Taking screengrabs is relatively easy. Taking grabs of obscure windows and other objects is less easy. There are quite a few excellent screen grabbing tools available, including Screenshot Captor and Faststone Capture, both updated regularly. WinSnap 2 attempts to go further than these two tools by including advanced image editing and effects so that you can add shadows and other elements to your grabs.
Maybe I'm mistaken, but WinSnap 1 used to be freeware and was only released recently? Some people would regard it as excellent marketing. I'd regard it as frustrating for the end-user: releasing a product as freeware, then ramping the same product to shareware, within a few months. Still, it's a good product and WinSnap 2 now supports Vista and enables you to grab Aero windows, so it's worth a look.
