Hi. My name is***** you for your question. How long
has it been since you upgraded to Windows 10 from Windows 7?
If it has been less than 30 days it's fairly easy to undo the upgrade.
Longer than that and it's a much bigger challenge.
Thank you. Then you have have two options. You can purchase a copy of Windows 7 and do a clean
installation of the operating system which is a lot of work as you will need to back up your files first.
You would also need to re-install any programs which you have added to the computer and still want to use.
It's a big job.
The second option would be to install a free program in Windows 10 which would make
Windows 10 look and operate like Windows 7. Would that be of interest to you?
