Windows 10 19H1 Build 18282 is now available to Insiders in Fast and Skip Ahead Rings. Microsoft notes that you will be able to choose between the real light and dark shell in Windows 10. Windows will now wrap the printer name if it’s longer. Windows will also add a shadow to Action Center, to match the shadow seen along the borders of our other taskbar flyouts. Microsoft is updating the Windows Update settings page to help you find the pause option easily. You will notice ‘pause updates for 7 days’ option directly on the Settings > Update and Security > Windows Update page.
