Then, second in the list, 'uninstall latest preview build'. Then, at left see Recovery, which lets you "Go back to an earlier build." Then, at very lower left, 'Update and Security'. Then wait a bit, then query for updates, see if your 10240 comes. It runs a diagnostic and when I did it, even though I get the updates fine, it said there was an error it fixed (in gibberish, I don't understand what the problem was). Be connected to the internet when you do this (were you connected before?).

Then, go to Control Panel, again select Troubleshooting then Windows Update. Will edit this post with the steps after I reboot that machine.ĮDIT: first look at this article. DANG I shut off my Win10 just before coming here, for I just woke up. It's not a rollback of OS version, but an option to rollback to a 'previous build'.
