How to fix hourly CMD window pop up appearing


In the last week a command window has started to appear/disappear on an hourly basis and can reduce full screen applications to the desktop

This behaviour can be traced to Microsoft Office - even if you don't have it on PC there is a Get Office icon that auto installs and it is this program that is causing the problem

To fix this:
1. Open Task scheduler
2. look in left column and Select the little arrow next to Task Scheduler library - this should reveal the layers below it.
3. Click little arrow next to Microsoft Folder
Click little arrow next to Office and in the right column, search for OfficeBackgroundTaskHandlerRegistration task and disable it.

this should stop the pop up from appearing.

IN some cases it helps to disable OfficeBackgroundTaskHandlerLogon as well
