Windows Hidden Tools

Are you a Windows XP User ? How many utilities do you know that is built-in Windows XP ? Notepad, Wordpad, Character Map, Calculator, Microsoft Paint, these are the few utilities that I usually use.But out of blue,Windows Xp is a fully loaded package which has a lot of apparently hidden utilities which are seldom accessed by a basic or normal computer users ; and trust me,they still pack a lot of punch.
