Microsoft is apparently implementing a nifty change which will allow users to remotely install apps across all their Windows 10 devices via the Microsoft Store website.

The idea here is when you go to the web page for an app you have already installed on one of your machines, you’ll be offered an ‘Install on my devices’ button. Clicking this will bring up a list of all the devices associated with your Microsoft account, and you can simply select any of these which you want the app installed on, right there and then.
