Microsoft first announced their plans to build an ecosystem of devices around your Windows 10 system at BUILD 2017. Since then they have been testing several features to bring this ecosystem to life. The ultimate goal is to make it easier to pick up activities and work you have started on other devices in this ecosystem.
Cortana, if you use the digital assistant on your compatible devices, will help you pick up where you left off on other Windows 10 devices. If you are using a Windows 10 based device and move to another Windows 10 device using the same Microsoft Account in about a 10-minute period, you will receive a notification in the Windows 10 Action Center. This notification will have shortcuts to websites that you were actively using on the other device.
This is very handy as you move between Windows 10 devices but what about when you are on your mobile device and want to easily get a website to browse on a larger screen. That is where the Continue on PC feature in the Windows 10 April 2018 Update comes in handy.
Updated versions of Microsoft Edge on Android and iOS devices now have a button that opens a sharing menu so you can share a website link to one of your Windows 10 devices.
