Updating the Hosts File on Windows 10

Thanks Ben. Meant to respond earlier.

Win 10… After installing LBFW and Starting a Site: error msg: “Local ran into an EBUSY error while trying to update the Host file.”
Went into my Anti Virus/ Security anywhere “Webroot”
Adv. settings - Shields - “uncheck” the option “Prevent any prog. from modifying the Host file”
