The app allows desktop users to request a car on their Windows 10 PC for the first time, although the final process must still be completed on a smartphone. In addition, the app adds Live Tile update so users can see the estimated time for when their Uber driver will pick them up without having to open the app. Finally, the app adds Cortana support so users can simply request a Uber car with their voice.
Microsoft adds that U.S. users will be able to get a free Uber ride with the launch of the Windows 10 app:
"All new users on Windows in the US will receive their first ride free, up to $20. Users can redeem this offer by entering "MSFTWIN10" in the "PROMOTIONS" tab within the Uber app prior to the ride."
We should note that at the time of this announcement the PC version of the Uber app is not yet available. Keep checking back later today.
As of 7pm ET we can confirm that the PC version is now available to download.
