Windows 10: Downgrade from Windows 10 21H1 to Windows 10 1507 Made my computer stuck in setup

My windows 10 computer that originally came with 21H1 Windows 10 was recently downgraded to Version 1507 from 2015.It wasn't meant to be on this version, but I thought that it could run it due to many people saying that older Windows 10 could run on the newer computers.After installing, and going into setup, Windows 10 1507 goes through the first two steps of setup before saying "Just a moment"And then crashing, restarting two times, and loading setup again. It seems to be stuck in this loop, and I can seem to do anything to restore it to 21H1 PLEASE HELP ME!

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

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.

 

Windows 10 forced download

I actually had a client call yesterday with an email problem. when I tried walking him through some steps, he says "Yeah, I don't see that there, but I think it's because it's updated to windows 10. It did that a few weeks ago. I came back in on Monday, and it said Welcome to Windows 10"..... I think I'd throw the computer out the window.
