Microsoft has provided an update on Office 2019, revealing that the  Microsoft applications will only run on Windows 10. In a support article for service and support of Windows and Microsoft Office, Microsoft has revealed you’ll need to upgrade to Windows 10 if you want the latest version of Office without subscribing to the company’s Office 365 service.

The standalone Office 2019 software will only be supported on Windows 10 and not any version low. This will however not affect Microsoft Office for Mac, which is a separate product with a different release schedule. Microsoft is also altering the support life cycle for Office 2019, so it will receive 5 years of mainstream support and then “approximately 2 years of extended support.”

Microsoft Office will be released in the 2nd half of 2018. The Microsoft Office 2019 will include applications such as 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 around the middle of 2018, and the software is primarily designed for organizations that aren’t using the cloud Office 365 versions.
