THIS! I'm not sure why the MS guy doesn't know this.
No doubt. Spartan will be an "evergreen" browser.
Will you be able to do a clean install with the free upgrade d/l somehow? Please say yes.
I'm pretty sure you can change your settings so that doesn't happen in 8.1.
Jim, I'm sure you are correct. I expect you will need Windows 10 to run this new Office. If you still with Win 7 you'll have to stick will Office 2013.
