If you find this useful - then Good For You! Otherwise, it may sound like Double Dutch, as most of it does for me! If the guy would just speak a little slower, it might help! Maybe by watching it a few times, I may begin to grasp some of it!
The thing I'm afraid of re changing over to Windows 10 is that some af the apps I have under Win 8.1 may stop working, and I may have to upload them again under Win 10. That could lead to unwelcome complications and conflicts, as happened when I upgraded to Win 8.1. As they say "The devil you know is better than the one you don't!"
