This article provides a workaround to an issue that triggers a stop error on a blue screen after you upgrade your system to Windows 10 Version 1607.

Applies to:   Windows 10, version 1607
Original KB number:   3083796

Symptoms

After you perform an upgrade to Windows 10 Version 1607 from Windows 7, Windows 8, or Windows 8.1, the system fails to start, and you receive a "PROCESS1_INITIALIZATION_FAILED" error message.

Cause

This issue occurs if you have the HIBUN application from Hitachi installed. Hitachi HIBUN is incompatible with a compression technology in Windows 10 Version 1607. To prevent data corruption, Windows fails to start after a Windows 10 upgrade in this scenario.

Workaround

To work around this issue, roll back the system to the previous OS, uninstall Hitachi HIBUN, and then upgrade to Windows 10 Version 1607. To do this, follow these steps:

1. Reboot the computer, and wait for the Windows Recovery Environment (WinRE) to start.
2. Click Troubleshoot, select Advanced Options, and then select Go back to the previous build.
3. Uninstall Hitachi HIBUN.
4. Upgrade to Windows 10 Version 1607.
