Windows 10: How to revert back to Windows 10 Professional after a Windows 10 Enterprise upgrade?

The company I do work for asked me to install Microsoft's "Company Portal" app, which I did. Installing this app upgraded my OS from Windows 10 Pro to Windows 10 Enterprise WITHOUT EVEN ASKING ME. Additionally, their servers were not able to activate Windows 10 Enterprise because this was my personal laptop, and not one of the company's laptops. So now I am stuck with an un-activated OS that I never wanted in the first place.How can I revert back to my original Windows 10 Pro? From what I understand, the product key for Windows 10 Pro is stored in my BIOS. This is a Dell 5530.I certainly

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.
