Dear All,

I have a Windows Server 2016.
The main problem was to unable to install the lates 2025-06 CU

First tried to stop Bits, Windows update, Cryptsvc service etc. and rename SoftwareDistributon folder but no success.
After that run sfc /scannow, it stucks on verfication at 50% all time
Than run DISM /Online /Cleanup-Image /RestoreHealth but it also failed.

Than run Dism.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase with success
After that: DISM /Online /Cleanup-Image /RestoreHealth /source:<other windows server 2016 C: drive> /LimitAccess with success

At this point the command DISM /Online /Cleanup-Image /RestoreHealth gave no error but sfc /scannow still stuck at 50% verification.

After some restart and try of sfc /scannow in Safe Mode, DISM /Online /Cleanup-Image /RestoreHealth give error 0x800f081f at 80% again.

Please help me to find out what is the problem.

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.
 
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.
