I ran across this tool the other day. It is a free piece of software that assists in removing unwanted adware, spyware and software that normally comes installed on a new computer. This software is commonly known as bloatware and can significantly reduce the performance of a new machine and only offers features that a user would not typically want or need.

This utility searches the computer and identifies pieces of bloatware and reports them to the user and then removes them as requested.

I have not yet tried it myself. It is for only Windows XP and Vista, and I have not run a computer with Windows in years (well at least a primary machine).
