BlueStacks
BlueStacks is currently the best way to run Android apps on Windows.
It doesn’t replace your entire operating system. Instead, it runs
Android apps within a window on your Windows desktop. This allows you to
use Android apps just like any other program. BlueStacks also includes
support for easy installation of apps from Google Play, so the process
is as seamless as possible. Even better, BlueStacks runs Android apps
and games with surprisingly good performance.
This solution can’t replace Windows with Android, but that’s not a
bad thing — competing solutions that allow you to dual boot Android with
Windows are currently unstable. This is only a solution for running
Android apps on Windows. Unlike many of the other options here, this is
a fairly stable and polished experience.
Similar applications, including YouWave and Windroy, lack the speed and easy app installation BlueStacks offers.
