I got windows 10 from an online ecommerce sit(extremely well known in my country). But the product key didn't activate windows ( i got an error). When I contacted them, they asked me to first contact the vendor. Now , the vendor asked me to enter slui 4 in run and then my installation id. Now, i didn't really think about it then. But now I am worried. Does that installation id give access to any private/sensitive info? Is it safe to give to someone?
