I have Windows 10 Build 10074 still, and it won`t detect any new builds.

[WPCentral Question]

Is there a fix here?

Maybe go back to WP 8.1, then try again to update.

yea just flash back and then you'll get the new one properly. I've done it several times no issue. There's no fix for 10074 to update if you can't update.
