I think when I went into to get the updates in settings there was an option to restore the last version. I don't know about turning the updates off in Win 10. I got a link but that's it.Just curious - how to 1) restore to earlier version and 2) shut updates off?

And this is for recovery of the last updated version that worked.

I haven't fiddled with shutting off the updates yet so I don't know if it works or not.
