Microsoft Corp. has told beta testers of Office 11, its next-version Office desktop productivity suite, that the product
will only work with the Windows 2000 operating system with Service Pack 3 installed, Windows XP and later desktop releases. While Office 11 is slated for release next year, today Win9x/ME/NT OSes
still hold about 52% of the overall OS market, and by next year's Office release, this is still expected to be around 40%. This is a tremendous amount of sales getting wasted (Office is the main income for Microsoft), but Microsoft said that this decision was mostly taken in order to incorporate new technologies on Office that are only available on the 2k/XP OSes, and also for security reasons ("
Windows 9x is inherently insecure" Sloan Crayton of Microsoft said).
