I never got BlueStacks (which seems to be in permanent beta - I’ve not yet seen a non-beta release, and it’s been at least a year) to run well (on a Dell Inspiron laptop running Windows 7). I’ve had better luck with DuOS (amiduos.com) on my Surface Pro 3 running Windows 10 (the Inspiron didn’t have the hardware virtualization support that DuOS requires). DuOS is free for 30 days (fully functional); if you want to use it longer, it’s US$15. Forever, though I don’t know if that includes updates. FWIW, after trying to get BlueStacks to run for weeks, I decided to pay for DuOS well before the 30 days expired.
