Thank you! We'll let you know when it's no longer working so you can get a small taste of the MSP space again :)

If you get the following error with System.Net.Webclient:
The request was aborted could not create ssl/tls secure channel

Just add this to the top of the script
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Still works :)
MSPs still exiting clients without proper cleanup.

Might be slower, but that that "Agent_Uninstaller.exe" is basically just a zip file. Use 7-zip, or whatever, to open the file and pull out both that Uninstall.exe and the Uninstall.exe.config files. Put those in the same location and run the Uninstall.exe. Takes a moment but should still do the trick.
