Hi. I`m trying to update Win server 2008 R2 using msu file with KB5061196 rollup update from microsoft update catalog and it failed with ERROR_SXS_COMPONENT_STORE_CORRUPT error in CBS.log. Could be important: last servicing stack update, KB5056456, installed successfully. When i tried DISM /online /cleanup-image /scanhealth command in CheckSUR.log i saw 18 errors, which wasn`t repaired automatically. I found this website and tried to run SFCFix.exe. It said to me, that there is 23 SURT total detected corruption count on the server. How to fix my server and update it to the last available rollup update? I attached necessary files to this message. Thanks!

Hi @who_cares,

Welcome to Sysnative Forums!

If you haven't already, please review the posting instructions here, and attach the requested log files. Without log files, our helpers will not be able to assist, and this will slow down fixing your machine.

If logs have been already been provided, our team of volunteers will analyse the provided log files to build a fix for your system. Please be aware that this may take several days from your initial post, due to the high volume of threads that we receive.

Sorry, that my previous message don`t contains what it must to contain. There is other necessary information, but i encountered another error: when i`m trying to upload CBS.zip there is an error "OOPS! We encountered an error while uploading" - somehow like this. Maybe its too large. I`ll upload CBS.log instead, if it`s important to upload full CBS folder - say it, i`ll find a way how to upload it, maybe with google drive

Hello and welcome,

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.
 
The attached COMPONENTS hive is from a Windows 10 machine, not from a Windows Server 2008 R2 machine.
Please attach the correct file.
 
Remove Update Manually
  1. Right-Click the Start button and click Command Prompt (Admin) on the list.
  2. When command prompt opens, copy and paste the following command into it, then press enter.
    wusa /uninstall /KB:3170106
  3. Let me know if it says it was successful or if there are any errors.

When i enter this command in the cmd i see: "Do you really want to uninstall kb3170106?". When i confirm it, then appeared progress bar. After that i see message: "Installer found an error: 0x800736b3. The referenced assembly is not installed on your system".
 
I google what kb3170106 contains and i think following information could be important: Internet explorer not installed on this server.
 
Ok, please do following:

Step 1:
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.

Step 2:
FRST Registry Search
  1. Click the Start button and in the search box, type CMD
  2. When you see cmd.exe 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, press enter afterwards.
    Code:
    REG LOAD HKLM\COMPONENTS C:\Windows\System32\config\COMPONENTS

    Note: This loads your components hive which is what we want. Please keep the command prompt window open while you perform the remaining steps. You can minimize it if you wish but keep it open.
  4. 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.
  5. Right-click on the file FRST64.exe and choose Run as administrator.
  6. Copy and paste KB3170106 into the Search box and click the Search Registry button.
  7. 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.
  8. You may close any remaining open windows now.
