Drush equivalent setup on Windows?
There are four possibilities:


Using Git Bash for Drush. Off the top of my head, this won't work for SQL commands, though
If you're using Windows 10, you may want to install the anniversary edition update. It gives a Linux bash shell. It also has its limits (no kernel modules), but those limits shouldn't impede Drush use
CYGWIN. It may take some fiddling, but may do the trick too
Try and persuade your client to use Vagrant, then run Ubuntu in there
