You can force the update by going to the Windows 11 page here and downloading the Windows 11 Installation Assistant (the first choice on the page).
Despite all Windows, Updates working ok, and the Laptop being on the list as a supported model, it has never updated to 22h2. From checking as much as I can find on Google, my registry shows its is marked as ready, and the Windows Troubleshooter shows no issues. The current build is  Ver 21H2 Build 22000.1574 which I understand is up to date. I am on Windows 11 Home version, Dell Inspiron model 15 5510 Any help would be greatly appreciated as I cannot find an answer on this forum or the web in general. Jim Baker
