Sounds like something I'd do, Magilla! However, since I was on the O365 Technical Preview, we were notified that O365 2016 would be released on September 22. Further, we didn't have to do anything at all . . . just let 'er rip!

I HATED office 2013 --went back to Office 2010 -- now using Office 2016 Pro (not the subscription version) and loving it.
The actual Technical Preview (TP) of O365 2016 began sometime in July 2014 and lasted until September 22, 2015. In order to join the Technical Preview when it started, you had to have a valid subscription to Office 365 2013. These rules were finally relaxed when the Public Preview was announced.
Those of us on the TP asked for an Insider Program for Office 365 when the September 22 release was announced. Our wishes were granted . . . probably because Microsoft recognized the value of the Windows Insider Program, not because we asked. They were probably planning it all along.
So, what this means is that I had to change Click2Run values in the Registry. Now I have Office Build 16.0.6366.2025! Whoopeeeeee!
Oh, yeah, I'm also happy to have access to all these experts. "such as you" Thanks.
