These elements are deeply embedded within the OS and you won't be able to extract them easily.
I've had to do the same as you for new users to XP and to Office and I used the method you are reluctant to use.
Take screen shots of the whole Desktop, use Paint to crop the image to the elements you want, save the new image as a bitmap, (for clarity), or jpeg, (for smaller file size), then embed them into the Office document using the Insert > Picture, (from file), option and add arrow/text etc as required using the Draw menu.
Here's one I did earlier;
There's no easy way to do this.
I am tasked with writing some basic documentation for the managers in our company that are unfamiliar for w/ WindowsXP and MS Office Suite, but are being asked to use it.
The problem is that I'd like to be able to imbed graphic from the XP GUI (the Start Menu Button, for ex.) and not just to take screen-shots.
What is the file extension for these elements? Or are they imbedded within another file type, and what steps are necessary to extract these into a form able to be imbedded inline with text in Word or Publisher?
Thank you in advance for any help that you can offer...
