Description

This task performs a silent, non-interactive uninstallation of UltraVNC on targeted systems.

  • Targeting: It identifies devices by looking for a registry key under ...\CurrentVersion\Uninstall that contains "ultravnc" and has an UninstallString pointing to unins000.exe.

  • Execution: It runs the uninstall command found in the registry and appends the /VERYSILENT and /SUPPRESSMSGBOXES parameters to prevent any on-screen prompts or wizards from appearing to the end-user.
