Windows 10: Can't download the latest update! Build 22478.1012

I've been experiencing a problem with Windows Update. I have received the latest Windows 11 Dev Build, 22478.1012. I am not able to download it completely, and thus, upgrade to it. I tried retrying several times, but the issue still persists. I am currently running Windows 11 Pro Dev Build 22471.1000, on my unsupported PC. It is still receiving every build.

Update Windows 10 to the latest build on Dell Vostro 3550

On my Dell Vostro 3550, I have updated from Windows 7 to Windows 8 to Windows 8.1 and then finally to Windows 10 when it was launched. I have noticed recently that my machine is not running the latest build and is still running build 10240 which I believe is the release build.

I have tried fixing Windows update errors and updating the system to latest build, but every time it fails without giving much insight to the error. I have checked Dell Website and this model is not listed for November update here.

I want to know if someone has succeeded in updating to Windows 10 on this model and if yes, what steps can I follow to do the same. If the answer is No, please guide me with other available options.
