Bluestacks one of the best performing Android emulator for the PC. Most of performance sensitive apps and games can run pretty decently in it.
But it comes with some catch. One of them is that you will be nagged to register with them, via One-Time Setup screen, most likely for sponsorship purposes. While in one hand it's just how the company makes money, in other hand it can annoy customer that does not want to opt-in.
In this tutorial, I will show one of the method to stop the One-Time Setup screen, so it will not pop-up every once in a while.
