Hi and welcome to Sysnative,

Do you have recent backups of this server, it's seems the Component Based Servicing hive is badly damaged.

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.
  

  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.

Hi! I don't have a recent backup. The error is probably cause by the motion of the the VM with Hyper-V from one cluster to another. It's been weeks. I realize the Windows Update error too late. Here joined the file. Thank you very much!

Hi,

As expected the Components Based Servicing hive is completely empty and missing almost all the subkeys. So please check the following folder: C:\Windows\System32\config\RegBack
Does it contain a copy of the SOFTWARE hive? If so please upload it to an file sharing service, then I'll send you a private message so you can provide the link for me, this because you cannot start a new private message with < 5 posts.

 

[Maibcool]

Do you have a way to copy it? It says that it is open in System.

 

[Maxstar]

Please do the following first.

Download

SFCFix and save it to your desktop.

• Download the attachment SFCFixScript.txt and save it to your desktop.
• Drag the SFCFixScript.txt file over the SFCFix.exe executable and release it.

• SFCFix will launch, let it complete.
• Once done, a file will appear on your desktop, called SFCFix.txt.
• Post the logfile (SFCFix.txt) as attachment in your next reply.

On your desktop you will also see a new file called SOFTWARE-bkp.zip provide this file in a private message.

 

[Maibcool]

Here it is.

@Maxstar I don't find where to send you a direct message. I'm new to this forum.

 

[Maxstar]

I've just send a new private message to share the link to the SOFTWARE hive.

 

[Maxstar]

Unfortunately, the Component Based Servicing key in this SOFTWARE hive is also corrupted beyond repair. Do you have a very similar server - patch level (17763.6532) and with the same features, language packs installed? If so then we can try to rebuild the CBS hive, but I would suggest to try this on a clone of the problem server first.

 

[Maibcool]

Thanks for your help. I will pass for now. The server is supposed to be decommissioned this summer. I will live with the problem for now. We can closed the case. Thank you!

You're welcome. And I will close this thread..
