Hi Jerry. My name is***** you for your question and the opportunity to assist. You can go back to Windows 7 but it
will take a bit of work. Basically you'd need to back up your data files and then install Windows 7 using recovery disks from the
manufacturer so you'll have all the needed drivers. Your software programs would need to be reinstalled and your files copied back to the drive. You can buy your own copy of Windows 7 but it's always less expensive to use recovery disks. I'd be more than happy to
help you with this.
You could also keep Windows 10 and modify it to your liking.
