My surface go did the update to 1809 . First of all it downgraded my Intel UD615 drivers to Feb 2018 and I had to manually install Feb 2019 drivers. Now Power save, high performance, and ultimate power plans are gone. I pasted the correct text strings for the missing plans in admin cmd prompt but they still don't show. No option to show additional plans. Everything was working beautiful WTF can't MS quit screwing the os? Tweak it if you must but it doesn't need this major update crap every six months. Anyone any suggestions I really want the plans back....what a PIA microsoft is... and I am expecting more crap to pop up...
