Phil,
thank you very much! This certainly explains why I'm having problems losing desktop connection in non-persistent VDI environment where ProgramData Folder is reset to its original state every time a user logs in. So every time a connection needs to be recreated either manually or by having cliet open for 2 minutes.
Do you know if the location can be changed somehow to point to %appdata% instead? Even if some functionality (when user is not logged in) is lost?
