Thanks for the advice, but Vista won't let me do so. I even turned off the pageing function. I have a 100Gb harddrive and after system installation i have about 75Gb free. I wanted to cut it down by 60Gb but the maximum Vista allowed me to do is 36.6Gb. To: clicq I have heard from other people that Vista is actually rather efficient as compare to XP, personally think it's almost the same. But that's just me.
