Introducing Meet Now in the Windows 10 Taskbar

Earlier this year we introduced Meet Now in Skype. Meet Now makes it easy to connect with anyone in as little as two clicks for free and each call can last up to 24 hours. Today, we’re excited to share that we will be extending this capability in Windows 10 by bringing Meet Now right to the taskbar. In the coming weeks, you will be able to easily set up a video call and reach friends and family in an instant by clicking the Meet Now icon in the taskbar notification area. No sign ups or downloads needed.
