Software :: Putting Windows7 On My Macbook?

I installed windows 7 on my macbook using bootcamp and apple told me how to log in under mac osx but they wouldn't help me beyond that.

when I log in under windows, there's no volume even though I've tried adjusting the volume. the screen is @ a low resolution and I've said "fine, that won't affect the machine's performance and it may take up more room anyway, I think?" I can't right click on anything. Also~ very important~ I can't get wi~fi under windows. However, all these things are not an issue when I log in under Mac OSX and everything works exactly as it did before I loaded Windows. I think I need drivers for windows but how do I get them??????

the reason I loaded windows in the first place was I have an external hard drive that has I believe 80 gigs of my music, pictures, documents, and other data. I did not know there was that many gigs of data on there and I had to guess as to the size partition I wanted for windows. I ended up making a 50 gig partition. I didn't know if it was possible to uninstall windows and reinstall it. I bought this copy of windows new and have only used it on this macbook. Also I don't have any data under windows (nothing I care about,anyway) only some music and other data under Mac OSX.

which brings me to another issue. When I log into windows, it says, "This copy of Windows is not genuine." But it is!

So these are my issues~
~how do I get windows drivers to fix keyboard issues?
~is it possible to uninstall windows and reinstall it so it has more gigs?
~why to goodness is it telling me this copy of windows isn't genuine?

~and I'm saying all this @ once because I don't know where to begin and I would really appreciate your help and time.
