Hello and welcome,

Copy the file C:\Windows\Logs\CBS\cbs.log to your desktop.
Zip the copied file and attach the zipped cbs.log to your next reply.
 
I don't see the error mentioned in your initial post.
Restart the machine.
Check Windows Update again and report the result.
If it fails, copy the file C:\Windows\Logs\CBS\cbs.log to your desktop.
Zip the copied file and attach the zipped cbs.log to your next reply.
 
I did a shutdown and power up. Launch the Windows update and it hahgs halfway for more than 2 hours. (refer attach for screenshot and CBS log)

Great. This time the log reveals useful information.

Remove Update Manually
  1. Click on the Start button and in the search box, type Command Prompt.
  2. When you see Command Prompt on the list, right-click on it and select Run as administrator.
  3. When command prompt opens, copy and paste the following command into it, then press enter.
    wusa /uninstall /KB:5022899
  4. Let me know if it says it was successful or if there are any errors.
 
FRST Registry Search
  1. Click the Start button and choose Control Panel.
  2. In the upper right corner ensure the View by: is set to Category.
  3. Select the Programs group.
  4. Click the Turn Windows features on or off link. This will bring up the Server Manager dialog.
    Note: This loads your components hive which is what we want. Please keep this dialog open while you perform the remaining steps. You can minimize it if you wish but keep it open.
  5. Download the Farbar Recovery Scan Tool and save it to your Desktop:
    64-bit: Downloading Farbar Recovery Scan Tool
    Note: Your antivirus program may report FRST incorrectly as an infection. If so, disable the real-time protection when downloading and running FRST.
  6. Right-click on the file FRST64.exe and choose Run as administrator.
  7. Copy and paste KB5022899 into the Search box and click the Search Registry button.
  8. When the scan is complete, a message will display that 'SearchReg.txt' is saved in the same folder FRST was started from. Notepad will open this file also. Close Notepad and attach the file 'SearchReg.txt' to your next reply.
  9. You may close any remaining open windows now.
 
Hi Peter, Upon launching steps 1-6, the FRST application takes forever to backup registry. I download Registry Finder and did a search for KB5022899 and report extract as attached. I hope thisiswhat you are expectng too.

  • Open Regedit.

    Click File - Export. Enter a filename and click Save.
    When successful done, browse to the registry key HKEY_LOCAL_MACHINE\SOFTWARE.
    Click File - Export. Enter a filename and click Save.
    Close Regedit.
 
As per

Maybe I wasn't clear. I just needed to know if you could backup the 2 hives. I didn't ask for it to attach.
I removed your attachment because the SOFTWARE hive contains sensitive information!.

Restart the machine.
Perform the instructions in message #8 again and report the result.
 
I am still getting the same result after server reboot (manual shutdown as remote shutdown hangs) and running mesage #8.
I do not have any issues running similar stepson another server.
 
Provide the Components Hive
1. Navigate to C:\Windows\System32\Config and locate the COMPONENTS file.
2. Please copy this file to your desktop.
Note: If you receive an error that this file is in-use, simply reboot your computer and try again. Note: If you find that you need to reboot and are unable to because this is a server then try Option#2 below.
3. Right-click on this file on your desktop and select Send To...Compressed (zipped) folder. This will create a file named COMPONENTS.ZIP on your desktop.
4. The file will likely be too large to upload here so please upload to Gofile or WeTransfer and just provide the link here.

Option#2 (only if you are unable to follow the previous instructions)

  • Please download the Freeware RegBak from here: Acelogix Software - Download products
     You will find it at the bottom of the page that the link brings you to.
  • Go ahead and install this program and accept all the defaults. After the last install screen the program should open.
  • Click the New Backup button. Accept the defaults and simply click Start.
  • When it says Finished successfully, click the Close button.
  • This will bring you back to the main screen of the program. You will see one entry in this list with the date that you did it. Right-click on this line-item and select Explore Backup...
  • This will bring you into the folder where the backup was made. You should see a Users folder and a Windows folder along with a couple other files. Double-click on the Windows folder to open it. Then open the System32 folder and then config folder. You should see around 6 files in here, one of which is named COMPONENTS.
  • Copy the COMPONENTS file to your Desktop. If the COMPONENTS file does not exist, please fetch it instead from C:\Windows\System32\config\COMPONENTS.
  • Now right-click on the COMPONENTS file that is on your desktop and select Send to > Compressed (zipped) folder.
  • Then please upload the zip file (COMPONENTS.zip) to your favourite file sharing website (it will be too big to upload here). Examples of services to upload to are Gofile or WeTransfer and then just provide the link in your reply.
  • You can close any open windows you have as well as the RegBak program now.
