Running genuine Windows 7 Home Premium x64 SP1, all updated, no antivirus or system tools installed.
Tried redownloading Windows 10 twice to upgrade via MediaCreationToolx64.exe
BSOD's at 32% every time and states:
Then resets to Windows 7 and states "The installation failed in the FIRST_BOOT phase with an error during SYSPREP operation".
Found this WIN10 KB on that driver: https://support.microsoft.com/en-us/kb/3074679
Seems ambiguous and i've uninstalled all windows 7 updates regarding opentype and adobe flash player security patches.
I need help getting past this error short of forcibly deleting the sys file and corrupting more things.
