z68 extreme3 gen3 - windows 10 drivers

I don't know if or when ASRock will add Win 10 drivers to the download pages of Intel 6 series chipset boards, like your Z68 chipset board.

So far ASRock has added Win 10 drivers for the Intel 9, 8, and X79 series chipset boards. We can see that includes models that are no longer sold among the X79 boards.

Adding the Win 10 drivers for all the boards will take time, if that is even possible. That depends upon the Win 10 drivers that are available from the various hardware manufactures.

Intel has the most drivers available, and AMD has their All In One driver package for some boards for Win 10. We can now see one or two from Realtek too.

The drivers that are included with Win 10 will allow as many PCs as possible to operate fine without any manual driver installation. The Win 10 Windows Update will detect and update drivers when others are available.

Don't forget that the Windows 10 Technical Preview versions have been available and used by many PC enthusiasts for months now. I've used that too and I never had a partially working PC after the various Win 10 TP versions were installed.

You don't need to worry about missing drivers with Win 10, it is designed to work with as many existing PCs as possible. Your Z68 board is not that old, and will work fine with Win 10.
