Which version of Windows are you using? 32GB or 64GB?
32Bit Versions of Windows will allow anywhere from 2GB to 3GB to be used as a maximum. Some of it will be used for the video card.
64BIT versions of Windows will allow all of your 4GB RAM to be seen and used.
There are some limitations when using Windows 64BIT on a boot camp partition. Currently, it is only supported on newer select intel Macs.
You cannot physically or via software add/move RAM from OSx side to Windows side. This is because you run Leopard and Windows separately and therefore when one is running the other is not active. The only thing that controls how much RAM Windows sees/uses is determined by the type of Windows you have installed (32BIT or 64BIT). Please do not confuse that with Gigabytes of RAM or disk space.
32BIT Windows has a maximum limit of 3GB of RAM (it often uses only around 2GB of RAM when it is sharing the system RAM with your video card. I believe this is the case with you.
64BIT Windows will be able to sees/use all of your 4GB of RAM.
Leopard sees/uses all of your 4GB of RAM.
If you have installed Windows XPSP2 and it is working properly on your boot camp partition then I can assure you that it is the 32BIT version.
FYI - The only time that one can select/decide how much RAM Leopard uses and how much RAM Windows uses is when one is running Windows as a Virtual Machine under software such as Fusion or Parallels. I have assumed that you are running windows on a boot camp partition (from your posts) and therefore this does not apply to you.
