Windows 10: Error 0xC004C003 Upgrading from Windows 10 Home to Windows Pro failed on Brand New Laptop

I just received my new ACER laptop with Windows 10 Home. After unpacking the laptop I turned it on and went through the Windows installation and sealing process. I then logged into Windows using my Microsoft account, saw that Windows was activated, applied all available Windows updates, and rebooted to apply all the updates. When Windows came back from the reboot, I logged in again and selected to upgrade Windows 10 Home to Windows 10 Pro from the Windows Update screen. I paid for the upgrade with my credit card. Windows then downloaded the update and displayed an Install button on the Wi

Can't activate Windows 10 pro on brand new laptop

Hi!

I just got a brand new laptop and erased the stock windows 10 home from it to replace it with a clean windows 10 pro install, This all went fine, I deactived windows 10 pro on my OLD laptop by using slmgr /upk and the key was removed from the machine.

When I try to activate the key on my brand NEW laptop(The edition has already been upgraded to windows 10 pro) I get this error: "0XC004C003 The product key used on this pc didn't work with this edition of windows" and I cannot activate it despite this being
a valid windows 10 pro key... When I restart my laptop it will say "Couldn't reach windows activation servers" and pressing the activate button does absolutely nothing.

What I always used to do is start a live chat with microsoft if this happend and they were able to fix my issue within 2 minutes by using SLUI however, when I try to access the chat link now, it says "This chat link has been discontinued" and I cannot use
it anymore.

Can anyone help me with this?

 

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.
