The next version of Windows 10 is codenamed 19H1 and is scheduled for release in April 2019. In 19H1, Windows Update now displays an icon in your notification area when you need to restart your PC for updates.
Microsoft has highlighted this new icon in a blog post announcing the creation of Windows Insider. 18290:
Starting at 19H1, when your device has an update that requires a reboot (including new versions that we publish), you will see the Windows Update icon with the orange indicator in the notification area (bar in the system state) prompting you to restart your device.
Some people may not like the extra clutter, we think it's a good idea. It's a more discreet way to highlight updates than a big "You need to restart your PC" message that interrupts what you're doing. When you see the icon, you know that you should probably restart your PC at some point in the day. Think of it as a warning before Windows Update becomes really boring.
This system tray icon was disabled by default on our test system. To enable it on Windows 10 19H1, go to Settings> Update & Security> Windows Update> Advanced Options and configure the option "Show notification when your PC requires a reboot to complete the update" on "On".
Right-click the icon and you will see options to restart immediately, schedule a reboot time, open Windows Update, or temporarily hide the icon.
This latest version also contains other interesting changes, including a microphone icon in your notification area indicating which application is currently using your microphone.
Microsoft has also added a "Sync Now" button and information about when your clock was last synced on the Settings> Time & Language> Date & Time screen. This should help you if your PC clock is out of sync – for example, if it fails to update for the summer time.
Other changes include the task list integration in Mail & Calendar, common design updates for the Start menu, and some updates to the Search and Cortana interfaces. For example, the Search and Cortana panes now support The new bright theme of Windows 10.
