Can't take screen shot in Windows Vista

Take a screen capture (print screen)

http://windows.microsoft.com/en-us/windows-vista/Take-a-screen-capture-print-screen

You can take a picture of what is on your screen by pressing PRINT SCREEN (PRTSC or PRTSCN on some keyboards). This is called a screen capture. You can then paste the screen capture into a document, e‑mail message, or other file. There are two types of screen captures you can take: the entire screen, or just the active window. For example, if you have three programs open at the same time, you might want a screen capture of only the active window.

Note

Some keyboards or mobile PCs that don't have the PRINT SCREEN button might use other keyboard combinations, such as FN+INSERT, to take a screen capture. Check the information that came with your computer or the manufacturer's website for more information.

To copy the entire screen

• Press PRINT SCREEN.

To copy only an active window

• Press ALT+PRINT SCREEN.

Tip

You can paste your screen capture into Paint, which is a drawing program you can use to crop, rotate, and resize pictures.

1. Open Paint by clicking the Start button , clicking All Programs, clicking Accessories, and then clicking Paint.
2. Click Edit, and then click Paste.
