AFAIK Dell will still sell you a new PC with Windows 7 Pro. (It will come with
a Windows 10 Pro license and Dell downgrades the OS to Win7 at the factory.)

Buying from Dell (or online) is a bit different from buying from a computer
store. I've never bought a computer online. I only buy from stores.

Even so, it's Windows or Windows so that's teh same thing since the
question really is about the business model and not the specific version of
Windows.

In the USA, you get a computer with Windows. Period.
You don't get any other choice at a store.

If you don't want Windows, you're welcome to delete it and put on whatever
you want (say Linux). But it comes baked in with Windows (generally the
latest version at the time of manufacture).

I was just asking if the business model is the same around the world where
all the non-Apple computers in the store have Windows baked in out of the
box.
