I'm running Win7 through bootcamp on a MBP and I have 4 gigs installed but it says that only 2 are usable. Is this because I am running the 32bit version of Win7 or should I have more RAM available?
 
Programs in Win32 are limited to 2GB of RAM in general. Your system will be using 3GB or so but each program only see 2GB usually. A 64bit OS will open up all the RAM but 32bit programs will still be limited.
 
not sure if all Windows 7 install disks are like this (i have windows 7 professional) but it has both 32 and 64 bit versions on it. You can use the same serial as well, even if it is a 32-bit serial. Just don't enter it when you install, then activate it after you have installed it. put win7 x64 on and you are good to go

Yeah it must be only for professional because I have home premium and the disk just says 32 bit 🙁 Oh well

Do I have to backup my programs if i do this or will it save them and just upgrade to 64bit.

Any 32<->64 bit install is not considered an upgrade, so you would need to reinstall your apps and data. You will also likely have to reactivate Windows over the phone.
