[SOLVED] Unable to install Windows Defender role due to 0x800F0831 Server A

Da_Jester · Sep 10, 2024

Hello Sysnative Team,
Hope all is well with everyone.
We are encountering yet a similar issue that was once resolved by Mr. @Maxstar (he rocks \m/) and in need of assistance to resolve 2 servers.

Thank you in advance and greatly appreciated as always.

Hi,

I've copied the logs for Server B to a new thread: Unable to install Windows Defender role due to 0x800F0831 Server B

Here's the fix Server A.

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.

Code:

DISM /online /cleanup-image /RestoreHealth

Hi,

Follow these instructions to remove an update.

Open the Start menu of Windows and type the command CMD
When you see Command Prompt on the list, right-click on it and select Run as administrator.
When command prompt opens, copy and paste the following command into it, then press enter.

Let me know if it says it was successful or you get the message: The update KB5003197 is not installed on this computer.

Hello Mr. Maxstar,

Hi,

Download the

Farbar Recovery Scan Tool and save it to your Desktop:

Download the 64 bit version: - Farbar Recovery Scan Tool Link

Open the startmenu and type the command cmd.
After you find the Command Prompt, right click on it and select Run as Administrator.
Copy and paste the following into the Command Prompt and press enter.

Code:

reg load HKLM\COMPONENTS C:\WINDOWS\SYSTEM32\CONFIG\COMPONENTS

Right-click on the file FRST64.exe and choose Run as administrator.

Copy and paste the following (code) into the Search box and click the Search Registry button.

Code:

KB5003197

When the scan is complete, a message will display that SearchReg.txt is saved in the same folder FRST was started from.
Post the logfile SearchReg.txt as attachment in your next reply.

Hi,

Start the

Farbar Recovery Scan Tool again.

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

Download the attachment fixlist.txt and save it to your desktop.
Right-click on FRST.exe and select "Run as administrator".
Press the Fix button.
If for some reason the tool needs a restart, please make sure you let the system restart normally.
When finished, a log called Fixlog.txt will appear in the same directory the tool is run from.
Post the logfile Fixlog.txt as attachment in your next reply.

Afterwards try to install the Windows Defender feature and post the result. If it fails attach a new copy of the CBS logs.
