6 months later, this app is still saving the day.  I get windows insider builds on the fast ring, which means I get updates VERY frequently.  For some reason, every time Windows 10 updates, it sets my nvidia card to the default gpu (old Optimus laptop), and I lose my intel graphics fix.
I know the nvidia control panel settings have nothing to do with surface tweak tool.  But is there any way you can detect when the fix has been lost and re-apply it?  I don't care if I have to have some .bat file in my startup folder if it means I don't have to manually apply the fix anymore.
