I used blustacks a while back when I didn’t know what it would do to my computer. I had to format my computer and reinstall Windows to get my computer back to the previous condition. I will now give you three reasons to support my view:
It diminishes the performance of your computer.
It creates a lot of junk files(system files) in your C-drive.
It uses the RAM wildly. And this leads to continuous freezing of the computer.
So, as you can guess I will not recommend Bluestacks.
