Couldn't upgrade due to 0xC1900101 - 0x20004 error.
When attempting to upgrade to 10158, 10159 or 10162, I'll get a failure. This failure occurs with Windows Update or via the 10162 ISO. It achieves 80% of the "Copying Files" portion of the installation process, which is 24% of the overall, and then it aborts and restore back to the previous OS.
The ISO base installation provides additional information:
0xC1900101 - 0x20004
The installation failed in SAFE_OS phase with an error during INSTALL_RECOVERY_ENVIRONMENT operation
Anyone else comes across this issue???
