I've finally managed to update to Windows 10 version 1511, here's how

After months of frustration I've finally took the time to update my Intel Compute Stick 1st gen to Windows 10 version 1511.
I tried updating it through Windows 10 Update but I would get the error that I needed at least 16Gb of free space on the stick in order to proceed, that of  'course is ridiculous since it only has 20Gb of free space in total so I got a USB drive with more than 4 gigs and I used the Windows 10 Media Creation Tool found at https://www.microsoft.com/en-us/software-download/windows10 , just hit download tool now, run it and then select Create installation media for another PC then your language, Windows 10 32 bit and your USB drive letter for the download process to start. After the tool finishes go to your USB drive and run Setup.exe

More information regarding the update can be found at http://www.intel.com/content/www/us/en/support/boards-and-kits/intel-compute-stick/000016164.html
  

My Compute Stick went into a boot loop after the November Windows update.. (possible fix)

The November Windows 10 upgrade was a major disaster for quite a few Intel Compute Stick owners. I was no exception. Thankfully I found a way to recover my Stick from a boot loop after the aforementioned update. Back in August I downloaded a Windows 10 .iso version 10240 and I used Rufus to write that to a USB drive I had lying around. The latest .iso from Microsoft would not boot or install for that matter so look for that August release and try a fresh install with version 10240. After the installation you'll have to visit Intel's site and conveniently download the "Automatically update your drivers" file that will install everything you'll need to get the graphics WiFi and Bluetooth going.
Everything seems to be running smooth after that but you'll have to go to your Windows Update options and choose "Advanced options" and check the "Defer upgrades" box that will disable the November 1511 upgrade from installing again soon.. One minor glitch after all this seems to be the recognition of my TV as speakers that needs a reboot to happen otherwise I sometimes get no sound..
Hopefully Intel will come up with a solution to the upgrade problem or Microsoft will release a new one that is more Compute Stick friendly. Until then try not to install the upgrade or try my solution if possible.
