Uninstall TeamViewer Using Group Policies

(Last Updated On: 2021-02-14)

When looking at GPO to uninstall software the answer is really simple. Group Policies can only uninstall software that was installed via Group Policies. Well even though this statement remains true we can still use Group Policies to run PowerShell Scripts or BAT files. These files in turn can be run by Group Policies to uninstall software like TeamViewer.

Even though the below is not limited to TeamViewer this can not be assumed that it will work other software and tests will still need to be made prior to rolling out the GPO.

The Script

The below script is done in Command Prompt and should work with most Client based Windows Machine. Even thought this was only tested on Windows 7 and Windows 10.

TeamViewer stores a lot of the config files in the Registry. This includes the installation location. The reason this is important is when you have different versions of TeamViewer you will have different folder Locations.

You can use the reg query command to find the InstallDirectory This Directory can then be stored as a variable where it can then be used to browse to the Directory and use the Silent Uninstall feature.

The code can be copied and pasted into a Text File and saved as a .BAT File.

For /F "tokens=1,2 delims=REG_SZ" %%G in ('reg query HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\TeamViewer /f InstallationDirectory ^| findstr InstallationDirectory') do set Loc=%%H
cd %Loc%
uninstall.exe /S

GPO

The Group Policy is fairly Straight forward to create. When opening the Group Policy Management editor, you create a new Policy with the correct Naming as per your Organization Setup. In the case below I used the following Naming convention.

CC – Computer Configuration
App: – This will make changes to a Specific App
Uninstall TeamViewer – What changes will be made to the App.

Once Created, edit the new GPO. Choose the path:
Computer Configuration >> Policies >> Windows Settings >> Scripts (Startup/Shutdown). Double click Startup.
