Hidden Programs in windows XP

I recently discovered that there are many programs hidden in windows XP. These program can neither be found in the start menu nor in any other location. Some of these programs are hidden in System 32 folder whereas some are hidden in the Windows directory. I've collected some hidden programs of windows XP from different blogs and websites. I knew about this trick when i was walking through www.tips-tricks-9.blogspot.com
