Then make Hyper-v home.

Seriously this is a killer feature needed by everybody. And specially the non-pro users.

Effectively all x86_64 hardware from the last 10+ years supports hardware virtualization, so I can't agree.

Aside from the points made by another reply (BIOS support, older CPUs), some machines have virtualization switched off by default because it's broken. I had a (fairly old) x86-64 laptop that would randomly hardlock while running VMs if I turned on hardware virtualization.

Not necessarily in the Bios settings. And there are CPUs without still.

£2,500 Dell XPS ships Home out of the box unless specified otherwise.

Windows SKU has nothing to do with hardware.

Actually I can't seem to configure that directly from dell to come with Pro lol. Seems there's a question about that too.

With Dell you have to buy the business version of a notebook to get Windows Pro. Your example would be [1][2]. Apart from price the main differences are that the business versions ship with Windows Pro and that they have better warranty (next-day onsite).

The Windows Store in Windows 10 has a "one-click" $99 upgrade from Home to Pro, Dell doesn't really need to offer it as a configuration item anymore.
