Please run the following commands again and attach Ditlist.txt to your next post.
Code:
dir /s /a %systemroot%\WinSxS\amd64_microsoft-windows-modernexecserver_31bf3856ad364e35_10.0.14393.0_none_01afe8e1a3859be2 > "%userprofile%\Desktop\Dirlist.txt"
dir /s /a %systemroot%\WinSxS\amd64_microsoft-windows-modernexecserver_31bf3856ad364e35_10.0.14393.2608_none_49c1957be790584a >> "%userprofile%\Desktop\Dirlist.txt"
 
Let's check the following folders as well.
Code:
dir /s /a %systemroot%\WinSxS\amd64_microsoft-windows-msaatext_31bf3856ad364e35_10.0.14393.0_none_7b761b7653ecd304 > "%userprofile%\Desktop\Dirlist.txt"
dir /s /a %systemroot%\WinSxS\amd64_microsoft-windows-msaatext_31bf3856ad364e35_10.0.14393.2879_none_c379137698019250 >> "%userprofile%\Desktop\Dirlist.txt"
 
I just want to let you know we're still looking into this, but it can take some time....
 
Hi,

Export CBS (Component Based Servicing) hive
  • Click on the Start button and type regedit
  • When you see regedit on the list, right-click on it and select Run as administrator.
  • When regedit opens, using the left pane, navigate to the following registry key and select it by clicking on it once.
    Code:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing
  • Once selected, click File > Export....
  • Change the Save as type: to Registry Hive Files (*.*).

  • Name this file ComponentBasedServicing (with no file extension) and save it to your Desktop.
  • Right-click on the saved file and choose Send > Compressed (zipped) Folder.
  • Attach the .ZIP file to your next post.
  • If the file is too large to upload here, upload the file to www.wetransfer.com and post the link in your next reply.
 
You have exported the Component Based Servicing key as *.REG instead of a hive file.
 
Can you explain to me what is the difference in export? Just out of curiosity.
When exported as hive file, the 'offline' registry component can be loaded into regedit on another system (VM) or an tool like Registry Explorer. In this way, you can explore the folder structure of the export, that is not possible when exported as REG file.
 
At this stage, I would recommend to make a backup of the server and then perform a in-place upgrade from the server ISO.
  • Mount the Windows Server ISO and run Setup.exe. You can use the Microsoft Evaluation Centre to download the ISO files.
  • Use the option Download updates, drivers, and optional features (recommended) and click Next.
  • Depending on your Windows Server version and license, you may see a screen prompting you to enter the licensing key.
  • In the next screen, select the image of the installed Windows Server edition and click Next.
  • Then accept the EULA. To perform a in-place upgrade, you need to check keep personal files and apps. Then click Next.
  • After clicking Next, an upgrade process will start checking for updates, when this is ready click install to start the in-place upgrade.
