Windows Fundamentals has found a cult following with a few gamers who take less than legal methods to obtain their copies. It is believed that because having an operating system that uses less RAM and CPU cycles makes high end games run better.
anyone got experience with this os? im getting a copy of it myself right as we speak so im going to try it out. but it looks promising with the removal of bloat from xp.
