Until you get a new computer I guess you just have to stick with 8.
I am curious how many people are having issues with Windows 10 . Windows 10 has been a nightmare for me . I tried it once and I had the issue of the start button not working . So I rolled back to Windows 8 . When I rolled backed to Windows 8, iTunes was damaged. I could not update or uninstall it. I waited and tried Windows 10 again and I had more issues . For myself, Windows 10 is a bug invested system. These are the issues I had to deal with while using Windows are :
-Start button not working
-Cortona not working
-Right click on taskbar icons not working
-unable to update or uninstall iTunes
-start screen apps not working
-Windows photos not working
-Windows store does not work.
