Sysprep Issue on Windows 10 IoT Enterprise LTSC 10.0.19044

Question

Hello everyone,

I'm trying to run sysprep on Windows 10 IoT Enterprise LTSC 10.0.19044.

I installed OS from ISO and before to connecting the PC to the network, I modified the 3 registry keys in orde to avoid the Windows Store apps update which were causing problems during the sysprep phase.

reg add HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsStore /v AutoDownload /t REG_DWORD /d 2 /f

reg add HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\WindowsStore /v RemoveWindowsStore /t REG_DWORD /d 1 /f

reg add HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\WindowsStore /v DisableStoreApps /t REG_DWORD /d 1 /f

I installed the drivers and updated the OS to the latest available patches and I captured the image using Acronis so as not to burn the image in case sysprep failed.

I attempted to sysprep using %WINDIR%\system32\sysprep\sysprep.exe /generalize /shutdown /oobe and everything was fine.

I restored the image created with Acronis, I completed the configuration of the "Golden image" by installing software (7-zip, Movicon, sql 2019 express, etc.) and created a backup with Acronis.

I ran again %WINDIR%\system32\sysprep\sysprep.exe /generalize /shutdown /oobe but unfortunately it doesn't work and I have these error logs:

Error TOOL BCD: BiUpdateEfiEntry failed c000000d

Error TOOL BCD: BiExportBcdObjects failed c000000d

Error TOOL BCD: BiExportStoreAlterationsToEfi failed c000000d

Error TOOL BCD: Failed to export alterations to firmware. Status: c000000d

Error [sysprep.exe] Parent device has unsupported type 5

Error [sysprep.exe] Failed to retrieve recovery entry WIM path: 0x32

Error SYSPRP WinMain:Hit failure while processing sysprep re-specialize internal providers; hr = 0x8007001f

How can I proceed in order to solve the issue?
