so guys recently i found out that i cannot upgraded the pirated version of 8.1 to 10 due to obvious reasons but i came to know that my university provides free windows 8.1 pro through onthehub and i had my university's IT department make me an account , so i just got the legit product key and works but tell me should i do a fresh install of 8.1 because i did remove the <Redacted> but i don't know if it worked, because i have not got an option to upgrade it to windows 10 it only says its reserved, and if i do a fresh windows 8.1 with a legit key will i be eligible for the free upgrade ? ....hope i don't confuse you all
