It would be a good idea to let Windows 10 replace Windows 7,this has already happened on my computer,both my father and brother's computers are working on Windows 10.There are two ways to get Windows 10 on your Windows 7 computer.
Method 1 is to upgrade to Windows 10. As early as 2019, Microsoft called on people to do so. It provides a free upgrade method.
Method 2 is to back up everything important and useful on the computer, and then directly do a clean Winodws 10 installation,everything will be a new beginning.
