Microsoft has released a fresh new build to Windows Insiders in the Dev Channel. Windows 10 Insider Preview Build 20221 brings some Taskbar improvements and several fixes to Insiders testing next year's feature updates.

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 are extending this capability in Windows 10 by bringing Meet Now right to the taskbar. You can now easily set up a video call and reach friends and family in an instant by clicking on the Meet Now icon in the notification area (system tray) of the taskbar in Windows 10. No sign ups or downloads needed.
