All of our Windows games, including Pretty Good Solitaire, work on the new Windows 10.
If you are installing on a new Windows 10 machine, you can just install using the downloaded install file just as on previous versions of Windows.
If you are upgrading to Windows 10, you may need to reinstall the game, although not always. Some people are able to just run the game after upgrading while others need to reinstall. Unless you erase your files in the process of upgrading, your statistics should also just be there after the upgrade.
