Many have upgraded to Windows 11 in supported or unsupported fashions.
Beyond 10 days unless backup images were made, those unhappy with Windows 11 had to clean install.
So if you want to try Windows 11 you may be able to in an unsupported fashion.
The default go back period is 10 days.
This can be modified to 60 days.
It's best to have free or pay backup images so that you can return to Windows 10 as needed.
