Microsoft introduced 64Bit Windows 2000
Microsoft and Intel jointly presented the preview release of 64-bit Windows 2000 for Intel's upcoming Itanium processor at Microsoft's Professional Developer Conference in Orlando, Florida. The Itanium processor (formerly known as Merced) will be sold next month with 800MHz.
Delivery of the '64-bit' Windows 2000 will begin at the same time. Since the beginning of the year, Microsoft has been offering developers who are not gifted with an Itanium prototype the possibility of accessing a 64-bit server farm via the Internet with a 32-bit Windows 2000.
