thanks for help. I own G551JW.
So to sum up:
- Microsoft provides drivers for laptop on Windows Update independent of Asus
- It is accident that Nvidia and Intel drivers installed through Windows Update match version on Asus support site
- We may expect that Microsoft will roll update through Windows Update for Intel Graphics drivers
Am I right with above statements?
Edit: Also, it is worth noticing, that we may disable installing drivers according to this manual: http://winsupersite.com/windows-10/stop-automatic-driver-updates-windows-10 . However this will block installing drivers like: NVidia, Intel HD Graphics, Realtek Audio, but will not block drivers like: Intel Chipset, Management Engine, Intel Wifi, Realtek Ethernet, Realtek Card Reader. Its complete nonsense to me.
