Windows 10 Mobile doesn't find new updates

[Windows Central Question]

I've got the HTC One M8 for Windows, currently running OS build 10.0.10586.164 and am on the Insider Release Preview ring. When I attempt to "Check for updates", it's not finding anything (even though there are more recent builds available - i.e. Anniversary Update). How can I force it to update? Do I have to factory reset it for it to be able to find the new updates?

Factory reset will get nothing other than revert to only 8.1. Don't do that.

There are ways of going to AU. Check m8 forum.
