If I run a batch file inside an cmd window ran as administrator before mining, it isn't stable or as good as running one line at a time AFTER mining starts.  That's a little awkward and I am still looking for a good way to automate that.  May have to go back to using powershell.  It has proved valuable for my VEGA 56/64 reference cards, took ETH mining from 44 to 47, not that that is even profitable right now.
