So, purchased a new laptop about a month ago. it came with Vista Home Premium 64bit and I used it for all of 5 seconds before installing Ubuntu 9.04 64bit. I do dual boot into it to play games every now and then. I have done a fresh install of Vista to delete all the bloatware, but want to know why Vista takes up 1.5 gigs of RAM, the lowest I have ever gotten it was 1.2 gigs, is there any possible way to get it lower? Why does it take up so much memory?
