Microsoft offers a built-in feature using which you can downgrade the new Windows 10 version to the older 8.1 or 7 and restore it. The feature makes the downgrade a rather trouble-free process.
You get a month's time to revert to Windows 7 or 8.1 after installing Windows 10. But before you go ahead with the process, ensure that you have created a backup of all data on your PC. Switching to an operating system is risky, as there is a good chance of losing data during the process.
It is recommended that you use external hard drives, thumb drives, or online cloud storage such as OneDrive, Google Drive, Dropbox or, Tresorit to save data. Once that is done, you are ready to proceed with the rest of the process.
PCAdvisor claims the downgrade is just a matter of 10 minutes. The only hitch was to change the shortcut to Windows Explorer in the taskbar, which had stopped working. Nevertheless, there is a fix available: right-click on the icon, unpin it from the taskbar and then search for Windows Explorer in the Start menu. Drag it to the taskbar and you should find everything working fine as earlier.
If you are confident enough, check out the following downgrade method.
