Now if you’ve upgraded your computer from Windows 7 or Windows 8.1 using the “Get Windows 10” app, you will see that after the upgrade, on the C:\ drive, there is a Windows.old folder, which contain all the files from your previous version of Windows. This also means that you can use the recovery feature to uninstall Windows 10 and rollback — in this case to Windows 8.1 with just a few clicks. In this video that I have added to YouTube will guide you with all the steps on how to uninstall Windows 10 from your PC and go back to Windows 8.1 by simply going to Settings > Update & security > Recovery and clicking the Get started button. There is only one caveat with the recovery feature, you can only downgrade to the previous version within the first month after the upgrade. After this month, you won’t be able to use Settings app option. In case, you’re reading this guide after the first month, you have a few other choices to go back to Windows 8.1. The first option is to roll back using the full backup you have created before the upgrade or by doing a clean installation of Windows 8.1.
