"Microsoft has noticed exactly this: the OS rarely uses completely its share of 2GB; so, they decided to support PAE (an hardware feature), to divide memory differently in 3GB for applications and 1GB for OS." I think you meant the /3GB switch here. The /PAE switch gives the OS access to memory above 4GB (how much it actually can use depends on Windows version), but each application is still restricted to its 32-bit address space. An work-around for this 4GB (per application) limitation is to use the AWE API.
