I'm sorry about the issue. Do you mean you'd like to go back from Windows 10 to Windows 8? When did you upgrade to Windows 10?
If you had upgraded to Windows 10 within the last 30 days, then please do the following:
- Click on Start (which is the Windows logo icon at the bottom left of the computer's screen), then click on Settings, then click on Update & security, then click on Recovery, then there, click on the option to go back to your previous Windows version there.
Please reply at the box below to continue troubleshooting. Thank you.
