OfficeBackgroundTaskHandlerRegistration flashes a window every hour
Is there a really, really good reason that the "OfficeBackgroundTaskHandlerRegistration" task (see it in Task Scheduler, Microsoft, Office) must run every hour? This is what it says that it does: "This task initiates Office Background Task Handler, which updates relevant Office data."
I ask, because it runs officebackgroundtaskhandler.exe in such a way that it flashes a window (itself) on the screen. Only instantaneously to be sure, but it's noticeable, especially once you catch onto what's happening. You can run the task manually if you want to see it without waiting.
Why doesn't the task use one of the many tricks to hide a window from displaying?

There are two scheduled tasks un Task Scheduler Library/Microsoft/Office:
OfficeBackgroundTaskHandlerLogon that runs when a user logs on
and
OfficeBackgroundTaskHandlerRegistration that runs every hour
Both were set to run under the "Users" account group. Since I didn't notice any popup at logon, I set OfficeBackgroundTaskHandlerRegistration to run under the "System" account and the hourly popups are now hidden. (Select the task, right click, Properties, click on 'Change User Or Group', type 'System', OK twice and voila.)
This is not the best solution from a security point of view, but until MS fixes it, it works for me.
