How can I take the Windows 10 demo off my computer?

[Windows Central Question]

For me, the Windows 10 demo is making a lot of actions more difficult than how my computer was set up before. Is there a way to switch back to my old computer settings?

How do you have it installed? Is it the only OS or are you dual booting?

If it's the only OS you're running, what version of Windows were you running previously? Do you have media to reinstall your previous version of Windows? Is your data backed up?

If you did a backup, it should be very easy to bring it back if you put it on a thumb drive
