I upgraded my laptop, no problems. I upgraded my wife's touch screen, no support for the TV turner card. Had to get 3rd party program. When her machine is idle, the CPU fan speeds up. Found out the background task "photos" was running while idle. Turned that off, system is OK now. Upgraded my sons desktop. Upgrade OK, but then upgraded his mother board. New board does not support IDE (SATA only) so I had to buy a SATA CD drive to install the original Windows 7, then upgrade back to Windows 10. (The original OS was on the IDE drive.) One problem is that I do not have the KEY for Windows 10. So if I have a disk die, or have to reinstall for any reason, I must reload the original OS, then use the upgrade thumb drive I created when I upgraded the machines to get back to Windows 10.
