How can the user actually remove the installed Office version completely and at once without having to do a lot of manual work. These are questions that users ask us again and again, especially when they have received new hardware and Office 2016 in 10-15 different language versions are partially installed there.
Normally, all of these must be uninstalled individually using the “appwiz.cpl” function (Programs & Features). With 10-15 Office 2016 packages, this is a complex and time-consuming task. But there can also be other reasons that we want to remove all office installations completely and without leaving any residue . For example, if there are problems with Outlook or the Office components such as Word, Excel or PowerPoint. Then usually no individual installation helps, then any remaining office residues may have to be manually removed from the Windows registry.
However, there can also be mixed office installations of different versions, as in the example below. Office 2007 and Office 2016 Home & Business are installed here at the same time, which usually does not work smoothly.
