People are often to afraid to mesh with windows settings. Sure there are things you beter don't mesh with but if there goes something terrible wrong then there is always a option to install it again. I normally have a hidden partion filled with an image containing a complete clean installation with all apps/software that I need. Is use Acronis True image. I boot, press F11 and within the 20min I have everything back before things went horribly wrong. I even can update the image with new versions of the applications etc..
