Windows 10: Upgrade to windows 11 after downgrading back to 10?

Greetings!I currently own a Pavillion gaming laptop that meets the requirements easily. The issue I am having is that when my Laptop initially recieved the windows 11 upgrade quite some time ago, it was quite unstable and crashed on multiple occasions, sadly by then I was way past my 10 days return limit the bugs were present earlier on too, but I didn't use it that much so I did not mind so I manually reinstalled windows 10.Around a month earlier, I made my Lenovo Thinkpad upgrade from 10 to 11 and it worked flawlessly, giving me hope that the kinks have been worked out, but since I manua

downgrade win 11 to win 10

I just reran the Media Creation Tool that I just downloaded a few minutes ago. It took less than three minutes to create the ISO file on my medium powered computer with NVMe SSD and 500 Mbps internet connection. Maybe try restarting your computer and downloading a fresh Media Creation Tool? Make sure to note where the ISO file is stored at the last step:

 

Windows 11 Home to Pro upgrade

Want to upgrade 11 Home to 11 Pro. Tried download, but apparently files transferred were for 11 Enterprise. This will not activate; error is "invalid digital license or product key". This is on a new Surface. How to proceed?

Can withdraw/delete this. The suggestion to downgrade - listed below - with a 'fake' windows 10 key works.

 

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.
