Per the ASUS Windows 10 upgrade guide:
Windows 10 MDA Microsites

On the ASUS G74SX-3DE notebook, the guide says to install v4.1.6 or above except ASUS USB Charger Plus won't start after successful installation as it will have the error "m_bBiosSupportV2 is false".

I reinstalled v2.0.8 which is for Windows 7 and it seems to run fine but I haven't tested the charging features.
