SomeOne help me with Chams

I have a vista computer. And i never see a comment saying "oh i have a vista and the chams isnt work so and so" So my question is that can i change the type of the computer that i have like to a window 7 bit thingy?

Help please

Vista isn't properly a computer, you know. To get Windows 7 you need to buy it on a local computer store.

So i can go to Best Buy or something, and if i install windows 7 will i have a better chance of getting the hack working?
