I give up. After weeks of irritating ads on my laptop for Windows 10, I finally upgraded. I figured that one day soon, MS would shut me down because I was still using Windows 7 and I would be stuck having to pay for 10. Besides their ads were slowing down my system. It was not as bad as I expected. What features Microsoft included seem to work. I expected to lose my 2003 Microsoft Office and other archaic software but it is all working. My 2003 MS Outlook still works but can not be integrated with their mail product. This is the first upgrade where I have not had to replace several hundred dollars of hardware after the upgrade. My Printers, scanner and everything else are compatible with the new operating system.
What is not working is my Norton Identity Safe. Apparently Microsoft does not play well with others and Norton has made some remarks about Microsoft changing their protection features faster than Norton can adapt to the changes. Microsoft is still making changes to the system and I think some features are missing that they will be added later. Identity Safe is the first software that I have found that did I could not get to work after a little tweaking.
The biggest challenges are in navigation. They are taking away a lot of the control and you have to learn how to adapt to the automation that they put between you and what you are trying to do but it is not as big a learning curve as going to Windows 7. At least I can do most of what I am use to doing. Their DVD player and audio player seem to have some commercials that you have to work your way around. Irritating but I don't watch many DVDs on the laptop. MS is trying to train you to do things their way but with a little effort, but they did hide options to allow you to by pass some of the the automation.
Overall, I would rate the change as better than most of their updates, acceptable but not ready for prime time. I did like the option of downloading a version configured for non touch screen laptops.
