If you try to upgrade from a Canary build to a Dev build, this is probably not possible. It doesn't have to do if the system is compliant or not. You must probably do a clean installation if you want the Dev build, otherwise stick with Canary. You can verify this with a Virtual Machine before attempting anything on your computer.

You can manually update like this.

Download iso that has been issued for this release, mount it as a drive and run setup.exe, selecting to keep everything.

Iso download must be same language as your primary installed language.

I've just used Windows Update to do the very same upgrade on my unsupported 'System Four' (see 'Other Info' in My Computers below).

At about 8% downloaded Windows Update will run the compatibility checks, which of course will fail.

After it has failed, replace C:\$windows.~BT\sources\appraiserres.dll with a zero byte sized file with the same name. Make one by making a New Text Document on your desktop and renaming it. Then click Retry in Windows Update, this time it will skip the checks and the download and install will run to completion.

Yes, I would treat my computer as non-compliant, even if it was and replace the appraiserres.dll with an empty dummy. To avoid any secret online compatibility check I would also disconnect from the internet during the upgrade.
