Semi related.  I'm still running on 2.9 and I don't see any reason to upgrade to 3.0 yet.  But I face one recurring issue that just won't seem to stop.  It runs best on windows fall creators update.  Problem is, windows continually tries to install spring update where the hashrate on 2.9 tanks by about half.  I have tried to disable update, even to the point of telling it to sign on to a different acct, but it STILL periodically turns itself on, and somehow updates itself.  Any ideas how to disable it once and for all?
