Win7 Pro Upgrade 32 to Win10 Pro 64

Hello,

I have a PC which originally had Win Vista Business 32-bit, upgraded to Win7 Professional 32-bit, then did a clean install to Win10 Pro 64-bit using the installation media provided on Microsoft's website. I was unable to use my 32-bit keys to activate Win10
Pro 64-bit. After some research, it seems I needed to upgrade from Win7 Professional 32-bit to Win10 Pro 32-bit using Windows Update or installation media, then take that key and write it down and use it later when I do a clean install of Win10 Pro 64-bit.

Before the clean install I used a program to find my product key for Win7 Pro 32-bit and wrote it down. If I wanted Win10 Pro 64-bit it seems I'd have to do another clean install of Win7 Pro 32, upgrade to Win10 Pro 32, then clean install Win10 Pro 64. Instead
of doing this time consuming task, is there some way I can get a key from Microsoft for Win10 Pro 64 bit, provided I have proof of my keys? The PC is currently running Win10 Pro 64-bit and is not activated.

Thanks

 

Migrating from Win7 Pro 32-bit to Win10 Pro 32-bit to Win10 Home 64-bit

My current computer started life with Win7 Pro 32-bit, and then I upgraded to Win10 Pro 32-bit with the free upgrade last summer. Now I'd like to switch to Win10 HOME 64-bit to take advantage of the extra memory I installed with my new mother board and CPU
last week on which Win10 Pro 32-bit is running.

Can this change to 64-bit Win10 HOME be accomplished using the activation code from my current Win10 Pro 32-bit (essentially the activation code from Win7 Pro), or must I purchase a HOME edition?

 

Windows 10 Pro 64 bit to 32 bit downgrade

There must be a step-by-step process to follow in order to move an existing OS from Win10 pro 64 bit to 32 bit. Any help with this would be greatly appreciated.
