If you aren’t entirely invested in running windowed Android apps with Remix OS on Windows, you can have your Windows and eat your Android at the same time with the Remix OS Player.
The team behind that interface (and devices running it) have made a virtual Android device that can be tailored to run on up to 3GB of RAM or as little as 512MB. The Remix layout is pasted on top of Android Marshmallow, but we guess the best explanation for this is to say that this is what Chrome OS wants to be as it begins to integrate Android apps into some Chromebooks. The usage paradigm between Windows and Remix OS is a bit wonky, but what do you expect? It’s a virtual machine, after all.
And you can get it down below for free — though there’s a hint of ad support going on. It’ll run on any PC with 64-bit Windows 7 or newer, an Intel Core i3 or better, 4GB of RAM, 8GB of storage and virtualization technology enabled in BIOS.
