Love your handle. How did you manage to freeze the screen, and copy and post it? I've seen this before, but never asked anyone how it's done.
To the right of F12 there's a button marked "print screen" or some similar abbreviation. You push it and the image is copied onto the clipboard, and can be opened/pasted with any image program.
I use Irfanview and XnView, a couple of freebie image programs, for most all of my dabbling, but you can do it with Windows Paint.

To post it, there's several free sites. I used this one, a no frills place:

Addenda: if you want to copy a small window, such as a popup window, hold down "ALT" and click the print screen button. That way it captures the foreground image.
