Hi,
Thank you for posting in Microsoft Q&A forum.
Per my experience, you can try Windows GPO to prevent users from uninstalling the applications. Windows GPO can be used to limit access to particular features and applications. You can manage the windows OS through GPO including the installation and uninstall of application. You can limit the use of certain windows installer components or prohibit access to particular control Panel items. Try below group policies:
\User Configurations\Policies\Administrative Templates\Control Panel\Add or Remove Programs\Remove Add or Remove Programs (If you enable this setting, Add or Remove Programs is not available to all users.)
\User Configurations\Policies\Administrative Templates\Start Menu and Taskbar\Prevent users from uninstalling applications from Start (If you enable this setting, users cannot uninstall apps from Start.)
Thanks for your time. Have a nice day!
Best regards,
Simon
