Solved - after 3 days it suddenly changed to saying Windows 11. Don't know what happed to make the change but all sorted now.
  Hello - after a tortuous round of attempts at getting my 7506 2 in 1 Black Edition upgraded to Windows 11 (see my other posts) it has finally worked!!! . But Support Assist still thinks I have Windows 10. Have uninstalled and re-installed it and re-booted etc and still the same. The Dell Update app does say Win 11 though. Will this really matter - will it still be offering updates for Win 10 when it should be offering for Win 11 ? Thank you
Support Assist still thinks I am on Windows 10
