MEmu is a high-performance Android emulator for Windows that is based on Android Lollipop. Unfortunately, it comes preinstalled with Android Jellybean 4.2 and upgrading to Lollipop requires downloading additional packages. It is compatible with Intel, Nvidia powered Windows PCs and unlike Remix OS Player, it is also compatible with AMD chipsets.
AMIDuOS, also called DuOS, is yet another Android emulator developed by American Megatrends, a Georgia-based company. Before installing DuOS, make sure that the “Virtualisation Technology” is enabled in BIOS and you have Microsoft Net framework 4.0 or above.
LeapDroid is a powerful Android emulator that was acquired by Google last year and eventually shut-down (you can still download it from other sources). But make no mistake, despite the discontinuation, LeapDroid still manages to be one of the most robust Android emulators around.
There are many more to use.
