Bluestack is a software which allows you to play android games and install android app on a PC. If you want to play or use android apps on computer then with the help of it you can. I like all the things in it . It has various features.It has a pre installed google play, a pre installed browser, camera, gallery, docs e.t.c.Inspite of all this there is a very big disadvantage of downloading bluestack.It works very slow.It will also slowdown your computer.Once you start your PC and start bluestacks then you have to be on bluestack.You can’t minimize it and open other software.You can’t even close it.After opening it you have to directly shut down your computer or wait for hours after clicking on the close button. If you want to install bluestack then you can but if you have a lot of other uses on your PC then it’s your own risk.
