Microsoft has been trying to get their consumer base on the same page as other companies. Apple has a constantly updating format. Google has one, as well. However, Microsoft always manages to suffer from back peddling when the base gets upset. Why do you think support for Windows XP stayed around for as long as it did? They want everyone to upgrade to Windows 10. In their latest effort, Office 2019 will only support Windows 10.
In a support article for the upcoming service, Microsoft announced that you will need to upgrade to Windows 10 if you want the latest version of Office. However, if you subscribe to Office 365, you have nothing to worry about. The mandatory requirement only applies to users that are not only their monthly service, which updates to their latest version automatically.
The requirement is designed to push businesses that have been holding off upgrading. Many businesses have been holding off upgrading to Windows 10, many of which are still running Windows 7. The standalone will require them to either upgrade their operating system to Windows 10 or subscribe to Office 365.
This will not affect Office for Max, which is a separate product and has its own release schedule. Microsoft is also altering the support lifecycle for Office 2019, so it will receive 5 years of mainstream support and then “approximately 2 years of extended support.”
Office 2019 (arriving in the second half of 2018) will include the usual Word, Excel, PowerPoint, and Outlook client apps, alongside server versions of Exchange, SharePoint, and Skype for Business. Microsoft is planning to release preview copies of Office 2019 in the middle of 2018, and the software is primarily designed for organizations that aren’t using the cloud Office 365 versions.
Microsoft is also extending its Windows 10 support for enterprise and education customers running certain versions of the operating system. Windows 10 version 1511, 1607, 1703, and 1709 will all be supported for another six months to help enterprise and education users move to the latest supported versions of Windows 10.
