Microsoft will release the first upgrade to Windows Server 2016 the last week of September.
"We'll be launching Windows Server, version 1709, at Ignite," Jeff Woolsey, a manager in Microsoft's Windows Server group, wrote on a company blog on Thursday.
Ignite, the conference successor to the long-running TechEd, will run Sept. 25-29 in Orlando, Fla.
Windows Server 1709, labeled in Microsoft's yymm release format, will be the first of an every-six-months upgrade cycle. The Redmond, Wash. company introduced the new cadence in June, saying at the time that it was synchronizing Windows Server upgrades with ones for both Windows 10 and Office 365.
