.. but having the ability to run Windows apps under Linux would be a plus.
Install Wine on your Linus computer. I have found it to work well in doing just that.
Yes scouter is right about “Wine”. An they just improved it to be much better at running Windows programs.
But you are asking about two situations. The concept in the article is Windows now allowing it to be easier to run a Linux under/inside the Windows environment. This is good for folks to make it easier to go try Linux to see what it really is and how easy it is to use. And then maybe make the switch to Linux from Windows later.
The second was your point about running Windows programs in Linux. This would come later if you choose to switch to Linux as your main OS. Then with Wine you can run “most” Windows programs on Wine. But Wine is not completely foolproof. Some apps have locked it so that it can only be run on windows. These particular apps do not always run with Wine as they should. It is sometimes hit and miss. But it is not the fault of Linux or Wine.
