how do I take a screenshot? is there a keyboard shortcut? I have Vista my processor is a core2 vista pro

To take a screenshot, press the button on your keyboard labelled "Print Screen" (or similar, like "Prnt Scrn"). Then paste it into paint and upload it on an imagehosting website.

Read this topic for a more detailed explanation on how to take a screenshot.

I get it now thanks for the help!

I tried it it does not want to work

Okay, what part are you experiencing trouble with?

taking a screenshot i pressed the print screen button but it didn't work it's crazy!

Did you attempt to paste it into Paint? Because nothing observable really happens when you take a screenshot, you have to open Paint (or a similar program) and go Edit > Paste to see if it worked. If that didn't work, try this:

Go to Start and open up the Help and Support Center. Type "Print Screen" into the search bar and click on the result which should be something like "Take a picture of what is on your screen". If your computer has a different Print Screen method than normal, it will be stated there.

After doing Print Screen .. if pasting doesnt work by mouse then try pressing Ctrl + V at the same time. [While Ms Paint window is out]
