One of the core differences between 32-bit and 64-bit editions of其中一個核心的分歧，在32位和64位版本 Windows Vista Windows Vista中 is of course how much system memory the two variants of Microsoft’s latest operating systems can use.這當然是有多少系統內存在兩種不同的微軟最新的操作系統可以使用。 Users have to understand that Microsoft alone limited 32-bit Vista to a maximum of 4 GB of RAM while taking the high-end editions of 64-bit Vista up to 128 GB of RAM.使用者必須明白，只有微軟一家有限的32位Vista中，以最多4 GB的RAM ，同時考慮了高端版本的64位Vista的高達128 GB的RAM 。 The fact of the matter is that Microsoft could have tailor fitted both 32-bit Windows Vista and Windows XP to address well in excess of 4 GB of system memory, but didn’t.其實，事情的是，微軟可以度身訂造安裝32位Windows Vista和Windows XP ，以解決遠超過4 GB的系統內存，但是卻沒有這樣做。 The best argument related to the possibility of introducing support for over 4 GB of RAM with x86 Vista and最好的論據相關的可能性，引進支持超過4 GB的RAM還有X86 Vista和 XP XP中 is the fact that Microsoft does feature 32-bit Window operating systems that do it.事實是，微軟是否特色的32位視窗操作系統這樣做。 Case in point Windows Server 2003, Enterprise Edition (32 GB of physical RAM), Windows Server 2003, Datacenter Edition and Windows Server 2003 SP1, Enterprise Edition(64 GB of physical RAM) and Windows Server 2003 SP1, Datacenter Edition (128 GB of physical RAM).例子，在Windows Server 2003的企業版（ 32 GB的物理內存） ， Windows Server 2003的數據中心版本和Windows Server 2003 SP1 ，企業版（ 64 GB的物理內存）和Windows Server 2003 SP1 ，數據中心版（ 128 GB的物理內存） 。 All these server side Windows operating systems are 32-bit platforms.所有這些服務器端的Windows操作系統的32位平台。

So why hasn’t the same been done with Windows那麼，為什麼有不一樣做了與Windows Vista Vista中 ? ？ Well, just because the 32-bit server operating好，因為32位服務器操作系統
