Google added a new feature to detect your current location on your desktop computer.

We've recently made it much easier and faster for you to start your journey on Google Maps from your current location. Now, when you visit Google Maps you’ll be automatically zoomed into your city as the starting point for your search. You can dive right in and discover the local businesses, restaurants and attractions near you, without having to manually enter your location.
