Synopsis

This script downloads the current Office uninstaller from Microsoft and tries to remove all Office installations on this computer.

If you wish it tries to install the newest Office365 build as well.

You can choose between 2 methods of uninstalling:
Default method will use the Microsoft Support and Recovery Assistant (SaRA) for uninstalling.
By using -UseSetupRemoval the Office365 setup method will be used.

Parameter

Parameter	Usage
-InstallOffice365	The script will try to install the newest Office365 build after removal
-SuppressReboot	No reboot will be executed after script is done
-UseSetupRemoval	Will use the official Office365 setup instead of SaRA
-RunAgain	Will skip the stage mechanism - whole script will run again
-Force	Non-interactive - No user interaction required
-SecondsToReboot [int]	Seconds until the computer will reboot

Example

.\msoffice-removal-tool.ps1 -InstallOffice365 -SuppressReboot -Force

Stage mechanism

To make sure that the program will only do the necessary parts a stage mechanism is builtin. After every stage a registry value will be written to HKLM:\Software\OEM\Heko-Bueroservice-GmbH\M365\Install\CurrentStage

To overwrite all stages and restart the whole script use -RunAgain.

Usage

You may use this script without explicit download:
