To take a screen shot and save it as a picture
1. Click the window you want to capture. Press ALT+PRINT SCREEN by holding down the ALT key and then pressing the PRINT SCREEN key. The PRINT SCREEN key is near the upper right corner of your keyboard. (Depending on the type of keyboard you have, the exact key names on your keyboard may vary slightly.)

Note: You can take a screen shot of your entire desktop rather than just a single window by pressing the PRINT SCREEN key without holding down the ALT key.
2. Click Start, click Accessories, and then click Paint.

Start, All Programs menu expanded to access Paint on Accessories menu
3. In the Paint window, click Edit, and then click Paste.
