Windows 10: windows 10 home to pro upgrade after a hardware change

I bought my laptop with Windows 10 Home and purchased and upgraded to pro successfully.

Recently I bought new 500gb SSD and replaced 256gb SSD, then reinstalled Windows 10 home.

Then i linked my microsoft account and tried to upgrade to pro...it's showing error

Activating Windows 10 Pro After a Hardware Upgrade!

I followed all the steps to linking my Windows 10 Pro to my Microsoft account so that I could upgrade my hardware, reinstall Windows 10 Pro, and activate it, but it's not working. I'm signed into my Microsoft account. I tried the activation troubleshooter,
selecing that I recently changed hardware, etc. Nothing is working. I can see my old computer under my Microsoft account, as well as my new one (with better hardware). I changed the motherboard, ram, and CPU. Any suggestions would be wonderful.

 

Windows 10 upgrade problem, no input accepted

I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

I will list some, or hopefully all, of the troubleshooting steps I have tried:

• Move keyboard and mouse to different USB ports.
• Try different keyboard or mouse.
• Restart computer, repeatedly.
• Google for related issues.
• Update Bios, because why not.
• Create boot media and revert to windows 7.

The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.

i've seen this when the stock USB drivers went kaput. Only ever seen it once - i used a PCI USB 2.0 card and connected the mouse and keyboard to that, and manually updated the USB 2/USB 3 drivers.
