A Microsoft Office bug is resulting in the “OfficeBackgroundTaskHandlerRegistration” task running every hour, which is frustrating users.
The task initiates the Office Background Task Handler, which updates Office data.
The bug, which runs officebackgroundtaskhandler.exe, means that a window appears for a very short time on the screen.
Microsoft said there is a fix for the problem, which will be available in an update for Office.
One Microsoft user provided the fix below for users who do not want to wait for the update:
There are two scheduled tasks in Task Scheduler Library/Microsoft/Office:
OfficeBackgroundTaskHandlerLogon that runs when a user logs on.
OfficeBackgroundTaskHandlerRegistration that runs every hour.
Both were set to run under the “Users” account group. Since I didn’t notice any pop-up at logon, I set OfficeBackgroundTaskHandlerRegistration to run under the “System” account and the hourly pop-ups are now hidden.
Select the task > right click > Properties > click on Change User Or Group > type System > OK twice.
