sfc /scannow gives no poblems

when i run: dism /online /cleanup-image /restorehealth
it gives an error : Error: 0x800f081f The source files could not be found.

When I run the component scanner:
The corruption scan completed after 64,54 seconds.
No corruptions were detected, but 2 warnings were found in the COMPONENTS hive.

Hi,

Step 1. Download

SFCFix and save it to your desktop.

Warning: This fix was written specifically for this system. Do not run this fix on another system.

• Save any work you have open, and close all programs.
• Download the attachment SFCFix.zip and save it to your desktop.
• Drag the SFCFix.zip 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.

Step 2. Run the following DISM command and post the result. If it fails attach a new copy of the CBS log.

DISM /online /cleanup-image /RestoreHealth

 

[Hoogen]

in the attachment SFCFix.txt. The command DISM /online /cleanup-image /RestoreHealth gives no error

 

[Maxstar]

Great, please run the following commands in an elevated prompt and attempt to update again. If it fails attach a new copy of the CBS logs.

net stop wuauserv
net stop bits
ren %systemroot%\SoftwareDistribution SoftwareDistribution.bak
net start wuauserv
net start bits

 

[Hoogen]

Unfortunately after running the commands Windows Updates still fails. In the attachment the new CBS.log

 

[Maxstar]

Export the Windows Update log

• Right-click on the Start button and click Windows PowerShell (Admin).
• Copy and paste the following command into it, press enter afterwards

Get-WindowsUpdateLog

• Wait for the message "WindowsUpdate.log written to C:\Users\<username>\Desktop\WindowsUpdate.log".
• Attach the logfile WindowsUpdate.log to your next reply.

Which update (KB number) is not working?

 

[Hoogen]

When I go to Windows updates it says: Updates failed last checked 30-03-2025 with below 3 updates with a download error. see picture

Which security software is installed on this server, e.g. 'Carbon Black (CB) Defense, Sentinel One, etc' or an external firewall that's blocking connections. This because of the following errors in the WindowsUpdate log. I've seen this combination of errors before and that issue was related to an external firewall which blocked connections to Microsoft servers.

0x80248014
WU_E_DS_UNKNOWNSERVICE - An operation did not complete because the service is not in the data store.

0x80072F8F
ERROR_INTERNET_DECODING_FAILED - WinINet failed to perform content decoding on the response.
ININET_E_DECODING_FAILED - Content decoding has failed
ERROR_WINHTTP_SECURE_FAILURE - WinINet failed to perform content decoding on the response.

Microsoft Defender. I checked the firewall but that is not blocking connections to MS

 

[Maxstar]

Open an elevated command prompt and run the following command. Attach Dirlist.txt to your next post.

dir /s /a %SystemRoot%\SoftwareDistribution > "%userprofile%\Desktop\Dirlist.txt"

 

[Hoogen]

Attached Dirlist.txt

 

[Maxstar]

Please run the following commands again in an elevated prompt and be sure everything is removed from '%systemroot%\SoftwareDistribution' and does not contain any remnants.

net stop wuauserv
net stop bits
ren %systemroot%\SoftwareDistribution SoftwareDistribution.bak
net start wuauserv
net start bits

 

[Hoogen]

a new one

 

[Maxstar]

Please reboot the server and attempt to update again.

 

[Hoogen]

Windows updates can check for updates but it does not download and install.

 

[Maxstar]

Microsoft Defender. I checked the firewall but that is not blocking connections to MS

Is this server hosted in a environment with an managed (HW) firewall?

 

[Hoogen]

Yes, together with some other servers who have no update problems
