GartnerGroup's Dataquest Says Windows 98 to Capture 51 Percent of Operating System Shipments in 1998

San Jose, Calif., June 17, 1998—Worldwide operating system shipments are projected to reach 110 million units in 1998, with Windows 98 leading the market with 56.7 million unit shipments, according to Dataquest, a unit of Gartner Group, Inc. (NASDAQ: GART). While new shipments for Windows 98 will be strong, Dataquest analysts said they anticipate modest to low interest in Windows 98 upgrades, with Windows 98 upgrade shipments totaling 5.5 million units.

"This is the last hurrah for the current architecture, the next version of Microsoft's consumer OS, Windows 2000, will be based on an NT kernel," said Chris Le Tocq, director and principal analyst for Dataquest's Personal Computing Software Worldwide program. "The business user transition from Windows 95 to NT Workstation is gradually emerging. Most new systems are shipping with 32 MB. With the rapid decline in DRAM expense, the investment in a Windows NT system begins to look substantially similar to the investment in a Windows 98 system." Dataquest projects Microsoft to have a 95 percent share of all operating system shipments on all computers worldwide by 1999 (see Table 1).
