Microsoft Office 2019 will work only with Windows 10
Microsoft continues the strategy of attracting Office application users to Office 365 subscription packages.
To a degree that targets business customers in particular, Microsoft has announced that the next version of Microsoft Office will work exclusively with the Windows 10 operating system. That puts the remaining companies to the Windows 7 or Windows 8.1 operating system in the choice between upgrading of Windows 10 workstations and subscription to Office 365.
This does not affect Office for Mac users, which is a separate Office 2019 edition for Windows, with its own launch calendar and pricing grid.
At the same time, Microsoft also makes adjustments to the length of time Office 2016 users will receive free technical support, guaranteeing full support for 5 years from launch and "approximately 2 years of extended support."
Microsoft will launch Office 2019 in the second half of this year. The package will include the regular collection of Word, Excel, PowerPoint, and Outlook applications, along with server versions for Exchange, SharePoint, and Skype for Business applications
