'which' is not recognized as an internal or external command, operable program or batch file.

### Prerequisites - [x] I'm using the last version. - [x] My node version is the same as declared as `package.json`. ### Subject of the issue Getting always this message in the console, whatever I do: `'which' is not recognized as an internal or external command, operable program or batch file.` Sample code works anyways ### Steps to reproduce Run the sample code from the [readme](https://github.com/microlinkhq/browserless) OS is Windows 10 Enterprise 64 bit. I get the same in console when I type `which`. So somewhere in the bazillion dependencies of node_modules, there is some script that tries shell code `which` for no real need. I've been digging around the code to try to uncomment any line that might cause this, but I still get that message. ### Expected behaviour Not get the console message ever. ### Actual behaviour Getting console message: `'which' is not recognized as an internal or external command, operable program or batch file.`
