Windows 2000 Gathers Momentum, According to IDC

FRAMINGHAM, MA — DECEMBER 4, 2000 — Adoption of Windows 2000 is not only rolling along, it's picking up speed and rolling over Windows NT. IDC estimates that during the fourth quarter of this year, shipments of the new operating environment will outnumber shipments of Windows NT by 1.7 million. By yearend 2001, Windows 2000 shipments could account for almost 71% of all Windows NT and Windows 2000 shipments.


"The majority of the transition to Windows 2000 is taking place now and will continue for the next 12-18 months," said Al Gillen, manager of IDC's System Software research.

According to IDC, Windows 2000 Professional, the replacement for Windows NT Workstation, is having quicker market acceptance than Windows 2000 Server. "This is not surprising," Gillen said. "The migration of a server from one technology to another is not a move that most managers make lightly."

IDC estimates by yearend 2000, Windows 2000 Professional shipments will account for more than 40% of combined Windows 2000 Professional and Windows NT Workstation shipments. By the end of 2001, Windows 2000 Professional's share will skyrocket to 72%.

"There are numerous reasons for this fast acceptance, including support for new hardware technologies that Windows NT Workstation 4.0 didn't offer such as universal serial bus, advanced power management, and plug-and-play support that really works," Gillen said.

Meanwhile, although Windows 2000 Server's adoption hasn't been as rapid, it is picking up now. It will account for approximately 35% of all Windows server shipments during December 2000, compared with just 16% for all of 2000. By yearend 2001, Windows 2000 Server will account for 56% of total Windows server shipments.
