wipe windows and install Linux 😉
oodles quicker, better battery life on laptops, comes with all the programs most people need on it already (office, messenger, internet, email, a photoshop clone, etc)
and its free, and all the programs are free!
and you never need to defrag it
reccomended (unless you play games and neeed windows)
you just need to download the cd image, burn it onto a cd, and run it as a normal installation disk

if you want to try it out without ballsing up windows, this program installs it inside windows as a program, so it can be uninstalled as easily as a program, but when you boot the computer, you can choose which OS to run. it doesnt run inside windows, it runs next to it, so even using wubi, you arnt restricted by windows being slow.
wubi is FULL ubuntu, it just means your hard drive still has windows on it, taking up space
