Windows Microsoft is planning to ship its next major version of Windows - known internally as version '7' - within roughly three years, CNET News.com has learned. The company discussed Windows 7 on Thursday at a conference for its field sales force in Orlando, Fla., according to sources close to the company. While the company provided few details, Windows 7, the next client version of the operating system, will be among the steps taken by Microsoft to establish a more predictable release schedule, according to sources. The company plans a more 'iterative' process of information disclosure to business customers and partners, sources said.

The original i386 could only address 4GB RAM. It had only 32 address bus lines.

The first x86 to break this barrier was the Pentium Pro, which had 36 address bits, hence 64GB RAM.

I don't know of any processors that can address 64TB of RAM.

32 bit address bus translates to 2^32 addresses, that much is true.
But, it doesn't mean that an OS running on a CPU with 32 bits address bus can only do 4 GB.

Here's how it can be done:

Solaris, Linux and Windows XP all support more than 4 GB of physical memory while being 32 bit for example.
