Bluestacks it was a android emulator for the windows operating system.
when I installed on the windows 7 lot of time to installation.
it was available an online installation version.so it can be take long time to install.
After install you got the blue stacks with android.
so cool Android in windows with lot of games and apps.
it was adjustable ram consumption programmed version but my 2GB laptop can heated like oven.
After work with the blue stack my windows lagged like snail.
it was useful of many apps especially whatsapp but your Ram may be equal or high than 3.
Dont’ go for blue stacks it can kill your laptop quickly.
