Uninstall all Zoom applications in a jiffy using Configuration Manager and Powershell

Introduction

Long story short, using Zoom these days for video conferencing , meetings, webinars and so on, is quite popular. However, Zoom has also received a lot of critique for being insecure, which has resulted in several articles on the topic.

For your reference, here’s a few of the articles:

The Zoom installation has the ability to be installed in the current user’s profile (consumer download), as well as onto the local machine in programfiles(x86) (enterprise download). This makes for some annoying situations, coming from an enterprise point of view, if and when you are asked to promptly uninstall all Zoom applications again (due to above reasons).

So I put together a Powershell script which can be run as SYSTEM with Configuration Manager. The script will find all installed Zoom applications, whether they are installed locally or in the user’s profile, and uninstall them automatically.

Powershell

The script can be found on my GitHub page: https://github.com/imabdk/Powershell/blob/master/Uninstall-EverythingZoom.ps1

The length of the script might be intimidating, but have no fear. The most lengthy part, is the function which enables you to invoke the logged on user’s context coming from SYSTEM. I needed this, so I could remove everything coming from the same script.

Thank you @Michael Mardahl: https://github.com/mardahl/MyScripts-iphase.dk/blob/master/function_executeAsLoggedOnUser.ps1

Configuration Manager

Package and Program

Use the script in a regular package with a program running the script:

  • powershell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile -WindowStyle Hidden -File .\Uninstall-EverythingZoom.ps1

Finding Zoom installations

You will also need to be able to find devices where Zoom are installed. Some of the installations are inventoried with hardware inventory, some of them are not.

Use this snippet of Powershell to find either, assuming they at least are registered with the Windows installer:

Configuration Item

Use above snippet of Powershell with a Configuration Item to locate devices with Zoom applications installed.

Below illustrations are the configuration taken from my environment.

Running the Script

Running the script manually for testing purposes can be done via psexec.exe.

See below illustration for inspiration, also showcasing that Zoom Outlook plugin as well as plugin for Skype for Business is being uninstalled.

ENJOY 🙂

  1. Thx for script 😉 It will be very usefull.
    One more point;
    It is better to define user profile path as variable, or detect it from registry. For some environment, user profiles are not in C drive, maybe in D or E drives etc.

    • You will need to create a Configuration Item as well as a Configuration Baseline, and based off of the deployment of the CB, you will be able to create further collections which will contain a full list of devices where Zoom is installed. (whether that be installed in the user’s profile or in programfiles).

      Let me know if this needs further elaboration 🙂

      • Hello, Martin

        Please elaborate, I’m not a “boss” on “Configuration Items” & “Configuration Baselines” yet 🙂

        • Ouch, I would think elaborating on everything around CIs and CBs will take more than a comment. What do you need specifically? My CI and CB for this topic? If so, please send me an email on mab@imab.dk and I’ll send you mine (an exported copy) 🙂

  2. I’ve verified everything with this in my environment (thanks so much for the CB and script!) but I can’t seem to get the package to run properly – I get an error when I run it – 0xFFFD0000(-196608) – I think I did everything correct except resolve this error, which seems to be some sort of file path running error
    As it turned out, 0xFFFD0000 is not a script error, but a path error. I recently changed a folder name where the script was located. So it was a simple path error.

    Is there any way you could show how you set up your script path to run in the Package and Program step? I’m not sure if I’m selecting the right options in there and its hard to find information about how to properly set that step up.
    Thanks!

    • Hi, I am trying to use your powershell Zoom script. I tested it on a fast push script to a particular device after adding the script to SCCM. Results of script seem encouraging.
      VERBOSE: Script is running
      VERBOSE: Running Uninstall-ZoomLocalMachine function
      VERBOSE: No Zoom applications found in HKLM
      VERBOSE: Running Uninstall-ZoomCurrentUser function
      VERBOSE: Registry path not found for user: localonly
      VERBOSE: Registry path not found for user: Administrator
      VERBOSE: Registry path not found for user: ENGL_Installer
      VERBOSE: Registry path not found for user: jdtest
      VERBOSE: Registry path not found for user: su-cmelay
      VERBOSE: Registry path not found for user: su-jdeering
      VERBOSE: Installed Zoom applications found in HKCU for user: su-ispencer
      VERBOSE: Uninstalling application: Zoom as the logged on user: su-ispencer (is that the problem?)
      VERBOSE: Script is done running

      However it doesn’t actually run the un-install and application remains. I added the script as a Program on a computer not device and guessed most of the settings in there. On setting in there was run with Admin rights and I did that ? Can you help with where to look for problems please?
      Many Thanks Ian Spencer

      • Hi, is the user in question actually logged into Windows? The script might find the Zoom application installed for the user, but the Zoom uninstaller probably need the user’s context in order to run. 🙂

  3. For a machine with multiple user profiles etc is there any implications? Will is recursively check each users appdata folder? Or does it need to run ‘If user is logged on’?

    • Are you running the script as the logged on user? (user rights in configmgr terms). If so, this will fail, as the uninstall is relying on coming from SYSTEM context. You should run this with administrative rights, and if run manually directly on your computer, you should run this with PSEXEC.EXE 🙂

      • command line:
        “C:\Windows\SysWOW64\WindowsPowerShell\v1.0\Powershell.exe” -ExecutionPolicy Bypass -NoLogo -NoProfile -File Uninstall-EverythingZoom.ps1

        still getting this error

          • that is a ps tool that is not on all the windows 10 machines. How would you call it in sccm? Put it in the folder in SCCM and run program first in the delployment? What would it look like in SCCM?

          • psexec let you test this manually, as system context is required. This is always a handy tool when troubleshooting configmgr related deployments. You don’t use psexec with the actual deployment in configmgr, but you use psexec manually when things are not working as expected.

    • Because WMI is slooooow as fuck. You can obviously do whatever you prefer. I tried WMI, and depending on how many products the device already had installed, the lookup took ages. Not to my liking. Also, not much error handling in that one line to cater for various situations. 🙂

  7. Thanks for sharing this information!
    Is there a way to make the user-based uninstall section silent? I’ve not found a way to do this.
