Take a screen shot from command line in Windows

This question's already been answered, but I thought I'd throw this in as well. NirCmd (freeware, sadly, not open source) can take screenshots from the command line, in conjunction with the numerous other functions it can do. Running this from the command line either in nircmd.exe's directory or if you copied it to your system32 folder: does what you want. You can also delay it like this: That will wait 2000 milliseconds (2 seconds), and then capture and save the screenshot.
