Re: Windows 10
I'll just share my experience with my Panasonic: it originally ran Windows XP. All the custom hardware drivers developed by Panasonic were loaded and were working fine. When I upgraded to Windows 7 there were a couple of missing drivers. I had to go to Panasonic to download them for Windows 7. They generally work well. I did say that my Panasonic laptop is running like a champ in my previous post, but that's only 99% true. The AMD GPU drivers, for reasons unknown (isn't that the case more than we want to acknowledge?) stops working and then restarts. It's not a big problem since I don't lose any work, but it isn't a great experience. Windows 10 is two OS generations after Windows 7, so I don't know for sure that it won't work, but it's highly likely that some driver won't work perfectly.
(What I need from an operating system right now Windows 7 fulfills it well. Windows 10 doesn't provide any benefits to me that I need, so I don't see why I would want to start on the path of searching for graphics drivers, reading forums for solutions, buying new hardware if necessary, etc. I'm guessing there are millions of others who are in the same boat as me.)
