Audio dead, touchscreen not working, after upgrade

After upgrading from windows 8.1 to Windows 10 touchscreen stopped working, audio isn't working, battery icon doesn't show on the taskbar, and that's the things that I've discovered till now. Solutions on the internet haven't worked, Asus doesn't have a driver update for it, Device Manager doesn't even show touchscreen.

I don't know if there is a solution for all this, or is it boding a bad experience and so I should roll back to Windows 8?

Boot into Setup (Bios) under Advanced or Integrated Peripherals. Look for Touch Screen or some such, if it is disabled, using your Arrow and Enter key Enable it.
Go to the Asus support/download drivers site, https://www.asus.com/us/search/results.aspx?SearchKey=%20transformer%20t100&SearchType=Products&Category=2-in-1-PCs&IsSupport=False&Page=1 find your model # and download any drivers you need from the Device Manager. You may need to update to the latest Bios. If all else fails contact Asus Support.

There was no option for touchscreen. It's as if the computer thinks there is no touchscreen and no audio chip. This is very strange.

Are there any yellow flags in the Device Manager?
Under Display, what does it say? Please upload a Screenshot of Device manager with Networking and Display expanded.
Did you download the drivers for your model from the ASUS page?

Also, recent update made it build 1709, shouldn't it be 18smth?

Okay after a couple of driver updates for the Intel processors touch is more or less back.

Great! If this solved your problem, please click the Thumbs UP icon in the lower Left under My Computer.

The Audio still isn't working
