my computer came with a product code on the bottom, before doing this i had been using my computer for a while and had already activated office starter because i didnt know it came with a product code. so today i had to use powerpoint but i noticed it wasnt on my computer

so then i saw the product code and i typed it in (this was for microsoft office home and student) but the product code said that it wasnt correct, i tried downloading a trial version that had powerpoint but it asked for a product code but nothing works!!

TL;DR if my computer comes with a product code on the bottom, is that code supposed let you access the full version of microsoft office? and if yes which version?
