Windows 10: Problem with Downgrading to Windows 10 Home

I had to change my motherboard a while back and had someone do it for me. He also had to reinstall Windows as he changed my computer from Windows 7 to 10. For some reason, the computer is installed with Windows 10 Pro when I have a license for Home. I tried to downgrade the edition myself by going to change some data on Registry Editor and installing an iso of Windows 10. However, I got an error message during the set up with the error code: 0x80070020 - 0xA001A. What should I do?

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

bsod after downgrading from windows 10 to windows 7


Hello there, tom.
I would try these:

• Get your Windows 7 media device and reinstall Windows
• Try auto-repair
• Follow these steps:

1. Put in your Windows 10 media device, boot into the USB
2. Select your language and keyboard input, then click next.
3. Click "Repair this computer"
4. Go to "Advanced options"
5. click system restore
6. Select a restore point before you downgraded to Windows 7.

Hope I helped!

 

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.
