Ok so I wanted to test bbzero, maybe I will sometime return but I don't have a time to joy more with it.
I uninstalled bbzero using bsetshell.exe
Actually, my Windows 10 x64 often ask for rundll32 permissions - I didn't noticed that before...
click ppm on audio button -> speaker or recording seettings -> rundll32 permission question
No, it don't ask for admin rights, just for permission.
How to fix that?
