Weird! Office 365 disappears after each dev channel upgrade

A month ago, I wrote about a strange issue with Office. It occasionally disappeared, was sometimes uninstalled after an Insider build upgrade. When I was last writing about this, it had happened three times out of five previous Dev Channel build upgrades. Find the whole story here: Windows Insider Dev Channel and Office 365 Can’t Get Along?

Since then, Microsoft has released four new Insider builds, and this has happened each and every time. The total is now 7 times out of 9.

I cannot understand this. See the title image above, that’s how Office apps are now shown in my Start menu. Each app consists of three entries. I have Outlook always set to start as soon as I sign in to Windows, but now after each upgrade, I am greeted with this:

Trying to launch any other Office application, something flashes on screen, too fast for me to see what it says. I had to capture my desktop to video, then play it really slowly to see what it is:

Apparently, Office is trying to reinstall itself.

Because Office is also removed from Programs & Features, meaning there is no Repair option available, my only option nowadays after every upgrade is to re-install Office from my O365 account page.

OK, as an issue, this is a minor although quite annoying one. The Insider team sends us a build every week, and I can spend a few minutes every week to re-install Office. But, that’s not the point: this shouldn’t ever happen.

I would be very interested to hear from you geeks. Have you noticed any issues occurring every time you upgrade Windows 10? Have you experienced weird issues with Office? Tell me all about it, please (comments welcome).
