Question: If I upgrade from Windows 8 to Windows 10, will I be able to downgrade if I change my mind?
Answer: Yes, you can revert to Windows 8 provided you performed an upgrade as opposed to a clean installation of Windows 10. There is a caveat to this, however. The downgrade option only lasts for a month. After that, Windows automatically deletes Previous Windows Installations files; the downgrade option also disappears if you ran Disk Cleanup since you upgraded. Provided neither of these things occurred, you can essentially try out Microsoft’s latest operating system with absolutely no risk. Just be aware that the free upgrade to Windows 10 will only last until July 29, 2016, so if you revert back to Windows 8 and later decide you want to settle on Windows 10 after that deadline, the upgrade will incur a fee.
To revert to Windows 8, apply the following steps: click on the Start button, an icon resembling a window at the bottom left corner of your screen. Then, select “Settings” and choose “Update & security” and then “Recovery.” An option to “Go back to Windows 8.1” should appear. Click on that, and Windows will guide you through the recovery process. Microsoft will also ask you why you have opted to revert to a previous operating system.
If your on-board copy of Windows 8 is no longer there, you can still downgrade if you have a copy of Windows 8 on disc or a USB storage device. Here, you must re-install your previous operating system as if it were a fresh install, but Windows will still walk you through the steps to do this. Just make sure you have your original product code.
