AMP, i have never used those features not 3rd party not win system restore.. most of time did disable it.. lately i don't even bother disabling it as it doesn't hug on my sys resources. since vista came out I never did a reinstall either
just enjoy computers like some people enjoy cars and bikes and know all its parts inside out. i don't claim to know windows 100% inside out but enough to keep it running smooth all the time. been with windows since windows 3.1, win7 is awesome no need to learn something new to get my work done and enjoy after-work time with it. although i will get mac at some point just to play with it
