My suggestion is that you leave well enough alone. The software in your computer was developed to give the user what they want. Although, I cannot see any immediate problem by the changes that are suggested, the gain is nominal, a few milliseconds of speed, that will probably be cancelled out by the speed of the website that you are visiting. I have seen many BSODs result from improvements that the computer user makes to the installed software.
I will tell you now others are going to come by and disagree. They will tell you try it, you can always reinstall, make a system restore etc. To them I say its just not worth the effort.
