WHen i built my PC i bought Windows 8 than upgraded for free to 8.1, than upgraded to 10 for free which is what i have now. I am wanting to install my OS to a new SSD but i fear if i try it my WIndows 8 Code will only work on Windows 8 due to 10 not being free now. I got Windows 10 when it first came out for free download. My windows 8 was a legal copy also. What i am asking is, will i need to buy windows 10 to use it or can i use my windows 8 code and it be used as windows 10? Also instead of deleting everything on my SSD cant i like copy everything to my new SSD? Or is that not possible?
