Problems after uninstalling

OTB Usage
1

Remove all orfeo elements

Windows10
Version of the OTB: 7.3.0
I installed the OTB with the binaries

I uninstalled Orfeo but when I start QGis I still get the message “the path of the additional plugin C: \ … does not exist!”. How can I remove it entirely?

Just solved removing OTB from the environmental variables.
