Hurried and updated the OS to the latest version, and now you are wondering how to rollback Windows 10 back to Windows 7 or 8.1? You can get back to your familiar operating system in several ways.
If you do not like the new operating system, then officially you can automatically switch from Windows 10 to Windows 7 and 8.1 within 30 days from the date of the update. If you want to return the usual version of the OS later than a month later, without saving the backup on removable media or in any free partition of the hard disk, then you will not be able to do this. Since the backup files will be deleted automatically.
To roll back Windows 10 to a previous version, you need to go to Settings - Update and Recovery - Recovery - Return to Windows 7 or 8.1, depending on the assembly that was previously downloaded to the computer. Click on the "Get Started" button and then select the "Back" option. Then the process of deleting new files will follow, restoring the settings of the selected version of Windows and the computer will restart itself. All personal data will remain intact, and applications and installations made in Windows 10 will be lost.

Click on the icon "Diagnostics" - "Additional options" - "Return to the previous assembly" and select the version of the OS that was installed earlier and suited you.
