Microsoft formally bans emulators on Xbox, Windows 10 download shops has this great article on how Microsoft is banning emulators from both Windows 10 and Xbox 1. By removing such emulators from its download shop. I am unsure if this means you won’t be able to directly download them and install them on Windows 10 but to quote the article.

The new rules also had bad news for anybody who wants to quickly publish an online multiplayer game via the Xbox Live Creators Program. Doing so will not be enough to enable cross-platform play. If you want your gamers on both Xbox One consoles and Windows 10 PCs to play with or against each other, you’ll have to submit your game to the ID@Xbox program and go through its own hoops and costs.
