Windows 10: Upgrading from Windows 7 to Windows 10 Home 64 bit

My son’s computer is running Windows 7 64 bit and I want to upgrade it to Windows 10 Home 64 bit. Of course I want to spend as little as possible for the license/upgrade and I found a couple on eBay that are pretty cheap Error Page | eBay
and Microsoft Windows 10 Home 64 Bit Full Version | Brand New | eBay

Are these licenses legit and will let me upgrade to Windows 10?

:)

 

Is there truly any reason to upgrade from Vista Ultimate 64 to Windows 7 64 bit?

Windows 10 Upgrade 32-bit to 64-bit

So, Windows 10 Upgrade is being rolled out worldwide, and I have 'reserved' my upgrade.

Currently my computer is running Windows 7 Pro 32-bit. I'm planning to 'upgrade' it to Windows 10 64-bit (via fresh install, of course).

After reading many references, these will be the steps I'll do:

1. Let the "Get Windows 10" app upgrade my OS to Windows 10 32-bit
   
2. Note the activation key
   
3. Download the Installation Media for Windows 10, but choosing 64-bit instead
   
4. Perform a clean install
   
5. Reactivate using the activation key in Step #2
   

(Of course I'll backup my data first.)

However, I still have some questions:

1. On Windows 7, the activation key does not differ between 32- or 64-bit versions. Is it still so with Windows 10?
   
2. Will I be able to download a different architecture on Step #3?
   
3. Is there anything I need to prepare beforehand?
   

Thank you for your assistance.

 

Is there a simple step by step to upgrade windows 10 32 bit to 64? I just upgraded from Windows 7 and there was no prompt for 32 vs 64 bit.
