At the time that I wrote these scripts, I was trying to clean up old agents that would not uninstall, did not show up under Win32_Product queries, didn’t have clean registry entries for the agents. And I had to get it done across thousands of endpoints, without downtime.
If you are a subscriber to ConnectWise Automate, go to the link in your Automate interface for the agent uninstaller and compare it to the one in the script above, that should resolve your doubts. I know it’s frustrating to trust a “random URL”, but that’s how you can verify it. Again, I haven’t used ConnectWise Automate in years, I just left this up here to help others.
@realchrisolin Your script is the “happy path” where everything is clean. I didn’t have that scenario. The Agent Uninstaller works no matter if whoever installed the agent made it so it would only uninstall if the server told the agent to uninstall itself, or if the agent got corrupted, or if the registry is broken.
