First of all why do this? Well it is a known fact that without Internet Explorer, Outlook, and some other Micro$oft components your PC should be Virus free. Also Microsoft is monitoring what you are doing and indexing your files on your PC. After you do this they won’t be able to do that any more. You should be aware though that you agreed to let Microsoft do this when you installed any of their newer software packages like Office 2007 or One Care.
