Spoiler Office 2019
Last year at Ignite, we announced Office 2019 – the next perpetual version of Office that includes apps (including Word, Excel, PowerPoint, and Outlook, and Skype for Business) and servers (including Exchange, SharePoint, and Skype for Business). Today we’re pleased to share the following updates:

• Office 2019 will ship in H2 of 2018. Previews of the new apps and servers will start shipping in the second quarter of 2018.
• Office 2019 apps will be supported on:
  • Any supported Windows 10 SAC release
  • Windows 10 Enterprise LTSC 2018
  • The next LTSC release of Windows Server
• The Office 2019 client apps will be released with Click-to-Run installation technology only. We will not provide MSI as a deployment methodology for Office 2019 clients. We will continue to provide MSI for Office Server products.

 

Office 2019

If your still running W7 why would you purchase Office 2019? You wouldn't.

 

Office 2019

Rats. And I just migrated from Office 2007 to 2016.

I don't have a problem with it working only on W10. W7 is already 9 years old. People need to finally let it go.

BTW, support for Office 2007 products ended last October. That's why I finally moved to 2016.

One thing I was really glad to see with that Office 2019 is it will still be a "stand-alone" product. I am still resisting, and will continue to resist for as long as possible, cloud based "applications as a service" type products.
