@nickaizoku I'am planning to Install Windows 10 and not seven , also it won't work because how I will transfer or know the files needed that Bluestacks keep so I take backup of them .
EDIT : I was able to found something that works , seems like the email stays related to the account forever so I was able to get the account back on my tablet I thought once it's linked and unlinked it cannot go back . ty for all your help
