After updated to creator update using the media creation tool. The windows update no longer works, always failed with 0x80070057. Tried use troubleshoot to fix it, problem remains. Try download any app from windows store, failed with the same 0x80070057 error instantly.
Try format the hdd then do a fresh install of creator update, big problem straightaway. Windows activation no longer works, failed with the same error of 0x80070057, win update and store same problem.
Hardware is stock standard Intel NUC 5i5RYH with WiFi and Ethernet. Only Ethernet is connected, IE/Edge works fine. Wifi driver is loaded but not connect to any access point. Try disable everything in Proxy setting, same problem. Tried disable firewall completely, same problem.
Restore to build 14393 everything works again. I notice at the last leg of installing 14393, the windows installer ask for which network to use (in Creator update it never asked).
EDIT: 20/04/2017. As reported, my original issues are resolved by updating the bios to the latest intel NUC bios. However, problem remains on many other users who are with different model of NUC.
