Microsoft is rolling out a new update to the Windows 10 People and Maps that will only currently be available to users in the Windows Insiders programs. These new versions come with a variety of updated features, which we will describe below.

The update for People app will change its version to 10.1806.1821.0. It's biggest change is that it removes the much reviled hamburger menu, which when used expanded a list of actions such as the ability to add a new contact, filter the contact list, access settings, and see the existing contacts.  These actions have now been moved to the top right of the app for easier access.
