Hi,
I have been using Steam for Linux - Steam Play on Ubuntu and Fedora Linux for some time now.
I was involved in initial testing efforts some time ago. See: Steam for Linux : Introducing a new version of Steam Play. If you run Linux, can you please test it out?
There are ~3500 Game titles now supported on Linux.

This article on phoronix gives some more information.

If you are interested please help test ACO, more information here:

Windows 7 support ends completely for consumers on Jan 14 2020: https://support.microsoft.com/en-us/help/4057281/windows-7-support-will-end-on-january-14-2020
If you are new to Linux or are considering moving away from Windows 10 to Linux when Windows 7 is EOL then I think https://forum.level1techs.com/ is a good place to join for friendly help and support.
Thanks.
