Microsoft Solitaire collection Preview:
You can enjoy Solitaire collection preview with the Build 10061. Yes, it brings classics like Spider and FreeCell for your gaming joy!! Check the settings and menu options in the screenshots below.
Cortana Find Song:
I am pretty sure this feature was not present in last build. You can use this feature to search and identify a song playing nearby. This feature has been present on Windows Phone 8.1 Cortana, especially in US.
This has been present on previous builds but this is the first time you can access, install and uninstall optional packages.
A new “contact support” app is here in the new build that helps you in contacting Microsoft support, in case you are facing issues with Microsoft services, apps, OS and others. Check the screenshots below.
