I too love TS3 as well.
And I also play on Windows 10 Home version but I never have any issues with my game and having to reset my settings after every Win10 update. I don't know but maybe it has something to do with the fact the my game was already on my computer when I upgraded from Windows 7 to the free version of Win10 before the offer expired. I mean I could be wrong about that but I've just never had any issues with my game and it's settings with Win10. I also the love the Windows 10 Creator that they've added about a year or so ago. I guess I must be one of the few who does love Win10, well besides my husband who needed to update to Windows 10 when the sites that he uses to pay the bills on stopped supporting WindowsXP. Plus he wanted to download and play a demo from Origin but it wouldn't let him as it kept saying that he needed to upgrade to Windows 10. So he had finally brought Win10 when he needed to buy a new hard drive for his PC.
