Uninstall of Personal Gateway is impartial

Hi

After uninstall of the PowerBI Personal Gateway the DIAHostService still runs and the powerbi gateway folder can be found in c:/program files, while all references to powerbi are gone in add/remove programs

Do you have any guides for manual clean uninstall of the gateway so I can reinstall it?

Regards
