Microsoft announced yesterday that future versions of the standalone Office 2019 app will work on Windows 10 versions exclusively.

The Redmond-based company recommends that users with older versions of the Windows operating system use the company’s Office 365 service instead, or update to Windows 10.

It’s unclear if Microsoft aims to block the installation of Office 2019 on older operating systems, or if it will allow it, but decline to fix any bugs.

The announcement, detailed in a servicing and support update here, is a clear and obvious move to drive more customers to Microsoft’s paid Office 365 service. The move might irk some customers who will likely choose to move to alternative apps, such as the open-source LibreOffice suite. LibreOffice 6.0 was released earlier this week with improved Office support.

Microsoft said it plans to release Office 2019 in the second half of the year. Office 2019 will receive five years of mainstream support and two additional years of extended support for paying customers.

Just like previous releases, Office 2019 will include Word, Excel, PowerPoint, Outlook, Exchange, SharePoint, and Skype for Business.

In addition to providing details about Office 2019, Microsoft also announced extended support for some Windows 10 versions. According to Microsoft, Windows 10 Enterprise and Education will receive an extra six months of support. Please refer to the table below for the new cutoff dates.
