It does work, but youll get a popup every 30 minutes about how the hardware isnt supported, and you need to migrate over to the new M$ data mining OS......I mean window$ 10. Theres a couple KB''s you need to hide/uninstall to remove this popup, it serves no functional purpose otherwise as win7 workes fine on 7th gen chips.
Just go here; download and read instructions. It excludes all telemetry and 'undesirable' updates. Very convenient. I'd advice that you integrate before you install, so you can have a fully updated copy in your storage for future installs.As I understand it, MS sent out an update on Windows Update that screws up WU on Win7 machines running Kaby Lake or newer hardware. In your shoes, I would find out which update it is, then vet all the updates coming in (disable the auto-install updates option) for that particular one then hide that update from the list and install the rest.
What programs don't work on Windows 10 that do on 7? You can easy disable the telemetry collection microsoft does.
