How to set no of Queue workers in laravel in windows and in shared server?

I am using Laravel 5.1, and I wanted to know if there is anyway with which we can increase the number of Queue workers in laravel... In its documentation, it's specified that we can do it by changing numprocs parameter with the help of Supervisor... But, how to do this on windows, as Supervisor is supported for only UNIX-based OS(es)... Also, Most probably, I will be deploying my application on Linux based shared server, so how to install supervisor there (because, server being shared, I don't think root access would be provided to me)??

Just for info, I am using database queue driver...

Thanks in Advance!
