Windows Vista and Windows 7 users are very familiar with the Snipping tool.
This tool is not a part of an operating system for the previous Windows OS like XP.
XP user who want this tool badly, can use the “Screen Clipping Tool” if they installed “One Note from Microsoft’s Office 2007”. Shortcut is “Windows key + S”
Or alternately can also use third party Snipping tool like “Snippy”
