I want to get Windows 8.1 64bit in my new Gaming Rig but im having a hard time finding a place to buy a product-key from. I dont believe Microsoft even sells them anymore. I was planning on
installing Windows 8.1 thru an ISO usb, so anyone mind helping out a newcomer be able to get Windows 8.1.

also If I buy a Windows 8 64bit Pro key will I be able to upgrade to Windows 8.1 64bit for free?

Yeah, if you buy a key for 8 you can get the 8.1 Update. Why would you want to use Windows 8 when you could use Windows 10?

You should try looking deeper through Microsoft's website and see if you can buy one through there.
You can always also do a search for something like "Buy Windows 8 64 bit product key"
I did one and I actually found a product key available to buy on Amazon

Although I'm not quite too sure if it's legit

Once you've gotten a product key, just download an ISO image of Windows 8 64 bit and install it on your computer with a USB.
During the setup, it may ask you for a product key, I believe in 8 or 8.1, one of them, you can skip the product key inputting, but when you're in Windows, the system will every few minutes or after an hour or 2 keep bragging you to activate windows and what not.
If you got a key, just put it in and you're done!

Oh, and also, yes, you can upgrade to 8.1 when you're on Windows 8, for free too, I think. Should be, I think. Once again download the iso for 8.1 64 bit and run the setup and let it upgrade you

If you want to be legit, you will need a retail license. Amazon has some listings.
If you are going to go to 8.1 anyway, you can just buy that version and skip waiting for the update to download and install.
Keep in mind you will also need installation media so if you haven't downloaded an ISO and created a DVD or USB you might want to make sure you are getting a disk with your license before you buy it.
