How to Take a Snapshot of a Windows Computer Screen. You can take a "snapshot" of a Windows computer screen and then turn it into a graphic using a graphics software application. This is useful for reproducing a Web page in print or for documenting an error message for technical support.
Step
Set up your computer to display the screen that you want to capture. For example, if you want to take a picture of your Web site, open your home page in the browser that you normally use.
Step
Press the Print Screen button on your keyboard. This captures a "snapshot" on the Clipboard.
Step
Open a graphics program, such as MS Paint.
Step
Open a new file.
Step
Paste the contents of the Clipboard into your document (Ctrl+V).
Step
Your file now contains an image of the screen that you captured. Name your file and save it in the graphics format of your choice.
