Note : During the installation, you’ll be presented with an option whether to preserve your data or not. Then, just follow the on-screen instructions to downloading and creating your own Windows 10 Bootable USB. To create an installation media, simply download the Windows 10 Update tool from Microsoft, and run it. Therefore, you’ll either have to use another system to create the installation media, or you can buy a retail disc online. One should note that you cannot create an installation media on Windows 10 S since you’re not allowed to run any apps not available on the Windows Store. To perform a clean install, you’ll first need an installation media for Windows 10. The second option, as always, is to clean install a fresh new copy of Windows 10 on your PC. Once done, your computer will restart, and you’ll return back to Windows 10 (Pro or Enterprise, depending on which edition you initially had). Your system will now reboot and it will start restoring your previous Windows files.Once there, simply click “Go back to earlier build” to start the rollback process. Finally, you’ll be presented with a screen that says ‘Thanks for trying out this build’. The restore setup will now present a couple of warnings about backing up your data and password.Simply enter any reason of your choice, and click “Next” to continue. You will now be presented with a new window, asking for your reason to revert back to Windows 10. Next up, Windows will prepare the setup for you.Click on the “Get Started” button below it to continue. There, you’ll see a heading that says ‘Go back to the previous version of Windows 10’. To start off, head over to Settings -> Update and Security -> Recovery.Also, before proceeding, make sure to backup all of your important data, just in case. Else, please refer to a different method. Note : The following method can only be used if it has been less than 10 days to your installation of the Windows 10 S. Else, you will have to resort to using another method. If such a folder exists, you can continue with this method. To check for that, simply head over to C-drive, and see if there is a folder named “Windows.old”. If you used the Windows 10 S Installer to install Windows 10 S on your PC, then your Windows 10 system files would have been preserved on your disk.
