This is my first ever thread on any website like this ever, so i apologise if i accidentally made a mistake creating this. About two days ago i ordered a Samsung SSD (it hasn't arrived yet) so that i could install windows on it to get an overall more responsive experience. However i just found my windows 10 disk that i originally used on this pc and noticed that the box with the original product key was gone. So my question essentially is can i still install windows on the SSD i purchased without having to enter in a product key (which i did when i first installed windows on my HDD). I did some googling around before making this post and i can't seem to find a direct answer from anyone.
