How can I roll back to Windows 8?

Glen got tired of all the errors in Windows 10 and he rolled back to 8.1. Leo said he did the same thing and you have 30 days to do so. But when Glen did it, he got an error message that the restoration was incomplete. Leo had that problem as well, and it's why he recommends always running a backup first just in case. Things fail, and that's why backups are important.
