I know this topic is old, but since I face this myself, would like to give some feedback. Now the Bluestacks installer is rubbish. If there people who made Bluestacks reading this, shame on you. The uninstaller leaves behind a lot of rubbish, a lot of folders need to deleted manually and it leaves behind rubbish keys like HKEY_LOCAL_MACHINE\SOFTWARE\BlueStacks. Now per Malwarebytes' scanner, it doesn't report any malicious activity, and Avira doesn't report any virus either. But Avira claims its a 'hidden object'. I don't like objects that hides itself on my PC, so I decided to use every obvious fix available, Malwarebytes' own RegAssassin, 3rd Party brute registry cleaner, MS own System Internal tools too change registry permissions and list goes on. Short story nothing worked, and most if not all the tools reported they couldn't 'see' this key despite running them using admin privileges. Salvation came from my secondary Linux OS as I read about a tool called 'chntpw' tool in Linux that is able edit Windows registries without giving any BS about not the detecting the keys. There are many tutorials that show you how to mount the windows partition in Linux and deleting these garbage keys safely. If you don't have a Linux OS, there are also methods describing booting Linux from USB or CD drive and running the tool from there like below. http://lifehacker.com/5584762/edit-the-windows-registry-from-a-linux-thumb-drive
