Windows 10 947 Published by

If you are one of the 1.2% of Windows Insiders who are experiencing an install failure at the 18% mark then this fix may work for you.



From SuperSite for Windows:
Beta testing a new operating system is full of challenges and with any new build it could easily go south for you.

For myself I successfully upgraded an HP Stream 7 through three Windows 10 builds but the latest one, 10122, brought me to a screeching halt with a DRIVER_POWER_STATE_FAILURE error.

I ultimately had to clean install build 10074 and then upgrade to 10122 to get the new build up and running.
