Take a USB stick, create a Windows10 setup with the MS Windows10 Media Creation Tool and do the setup from scratch.
If you install Windows® 10 from scratch will voids the Intel® Compute Stick warranty http://www.intel.com/support/motherboards/desktop/sb/CS-035602.htm
What I am suggesting is to contact Intel® support. http://www.intel.com/p/en_US/support
Well. it seems we rent a stick.
For 129 euro's there is no solution to solve a problem for Windows 10 crap.
Or is it so that this stick does not work with windows 10 @ all ?
Couse next thing after contact is .. your stick haves some problems .. bring it back because its NOT good.
Even a Windows 10 stick seems to be an old Yabba Yabba stick that has a wrong update etc.
Give a nice image and 100% support, we pay for a complete system !
If Intel cant handle the issues then stop selling this mini PC.
I would like to recommend you to follow the steps in here to perform the Windows 10* upgrade in your Intel® Compute Stick.
