One of the first advantages of Windows 7 64 bit over 32 bit that people point out is that 64 bit W7 can handle more than 4 GB of RAM (while 32 bit version supposedly can use only up to 4 GB). I mean, that's the first answer that you get when you ask why you should switch to 64 bits. People put it as if that was a technological thing, as if it was not possible technologically to have access to more than 4 GB of RAM when using 32 bits.
But hey! Previous versions of Windows could handle more than 4 GB RAM in 32 bits! ( http://msdn.microsoft.com/en-us/library/windows/desktop/aa366778(v=vs.85).aspx#physical_memory_limits_windows_server_2003 ).
So why didn't they bother to implement that capacity in Windows 7 32 bit? Especially since Windows 7 was much newer than, for example, W2003.
