The cabs are only for TF3D, they do not change the start menu or programs. You have to do the reg edits in the first post to change that part. Ive changed mine to red throughout, and ill post a screenshot in a few. Found this site if you are trying to go for any other color. Just ignore the # in the HEX and add 00 to the end of the value.
