Trouble uninstalling Skype for Business 2016 and Web App Plugin

Question

Hello,

I need a lot of help uninstalling Skype for Business 2016 and also the Web App Plugin from multiple PCs, using SCCM for deployment. I've tried for hours now and have had no success and at my wits end.

1. Skype for Business Web App Plugin - Will not uninstall for all users.
   Running "MsiExec.exe /X{37C8167B-B653-4955-A6E8-EBB8DE937DDD} /q" manually from an elevated cmd prompt only removes it from my profile.
   It's removed from my add remove programs, and also from my profile directory - C:\Users\Me\AppData\Local\Microsoft\SkypeForBusinessPlugin\15.8.20020.400\
   However, the files still remain for any other profiles in the appdata directories on the same PC. Also, there is still a registry entry for it that resides at HKEY_LOCAL_MACHINE\Software\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall{37C8167B-B653-4955-A6E8-EBB8DE937DDD}
   I tried deploying through SCCM and no luck either.
2. Skype for Business 2016 click to run
   I can't seem to find a working syntax for an .xml file that will just remove it and not remove office as well.

Please help, my sanity relies on it.

1. As far as I know, Skype for Business Web App Plugin is user profile based, so we need to run commands to uninstall it under each account. Maybe you could seek help from 3rd-party tools.
2. Do you install this Skype for Business 2016 with Office Professional & Plus 2016 installation?
   If yes, to remove Skype for Business 2016, you may run Setup.exe (The executable program is included in installation files.) in maintenance mode and make changes to an existing Office installation.
   • Please copy the installation files to your computer or a shared folder first, I create a folder called "Office 2016" to save these installation files.
   • Here is a configuration file (.xml) and I name it as "uninst1.xml", then put it into proplus.ww folder.
     <Configuration Product="ProPlus">
     <OptionState Id="LyncCoreFiles" State="absent" Children="force" />
     <Display Level="None" CompletionNotice="No" SuppressModal="Yes" AcceptEula="Yes" />
     <Setting Id="SETUP_REBOOT" Value="Never" />
     </Configuration>
   • Run the following commands, and please wait for a moment.
     cd <the path of source files>
setup.exe /modify ProPlus /config proplus.ww\<.xml file>
