There’s bad news for companies that do not plan to roll out Windows 10 any time in the foreseeable future, as Microsoft announced just recently that the next iteration of Office 2019 will not support any legacy versions preceding Windows 10. It is currently not possible to tell whether the new Office suite will run on older Windows versions. But it is extremely unlikely that Microsoft will offer support.
What’s more, Microsoft is reducing the support period from ten to seven years, so the end of support for Office 2019 will be October 14, 2025. But this will not affect the five-year mainstream support, and only the extended support (security patches) will be cut from five years to “around” two years.
The purchasing model will remain unchanged, so – unlike Office 365 ProPlus – the standalone version will not require a subscription. Only the installation method will be modified: The Office suite can be installed by click-to-run, and there will no longer be any MSI packages for this version.
An initial preview version of Office 2019 is penciled in for the second quarter of this year.
