Here are some of my favorite screenshot tips that I have discovered for Microsoft Windows. Enjoy!
1. Take a screenshot
It couldn’t be easier: just press the Print Screen key on your keyboard (sometimes abbreviated to Prnt Scrn) and the contents of the screen are copied to the clipboard. You can then paste the screenshot into Paint, Microsoft Word, or another program.
If you just want to copy the contents of the currently selected window, hold down the Alt key while you press the Print Screen key.
2. Grayscale anything (Windows XP only)
Here’s a sneaky trick: You can easily turn any part of the screen into a grayscale version. First, make sure the part you want to capture is not in the center of the screen. The click the Start button and click Log Off.
As you probably know, after the Log Off dialog appears the screen will slowly fade from color to grayscale. But if you use the screenshot tip mentioned above, you are able to use that XP “eye candy” to take a screenshot of the now-grayscale screen.
3. Overcome screen-capture prevention
If you use tip #1, you may come across programs that prevent you from taking screenshots. If you’re sure that it’s legal to take the screenshot you want to take, you might be able to overcome this by first holding down the Ctrl key and tapping Esc twice. Then press Print Screen. Note that it will not work to tap the Windows key twice.
