I have access to
http://www.asus.com/US/I had this issue about3 weeks ago when i was doing my pray to (RNG) god i hope my models next on the update list type of browsing to see official release of Win10 drivers.
I just downloaded all the newest drivers for Win-10 whish i needed most, not all running a AMD hybrid an the VGA drivers have changed 100% to Crimson:Edition which is way better improved, but anyways, try my link or /type in the address.
I think they update servers to load up the new drivers, long as its registered it should be located in the account page under Devices an clicking the Model should head straight to the support/download page
