Hello Peterj

Thanks for your help. When I try to uninstall the update, I get the message KB458346 is not installed on this computer.

I get the message KB458346 is not installed on this computer.

I assume you mean KB4580346, not KB458346.


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.
   
   

   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 KB4580346 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.

Hi Peter,

I followed the instructions and attached the file.

Step 1:
Warning: This script was written specifically for this user, for use on that particular machine. Do not run this script on another machine.

1. Download the attachment fixlist.txt and save it to your desktop.
2. Right-click on FRST64.exe and select "Run as administrator".
3. Press the Fix button.
4. The tool will now process fixlist.txt.
5. If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
6. When finished, a log called Fixlog.txt will appear in the same directory the tool is run from.
7. Attach the logfile Fixlog.txt to your next reply.

Step 2:
Restart the machine.
Run the command sfc /scannow in an elevated commandprompt 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.

Hi Peter,

Thank you for your support. After the fix was completed, I was able to reinstall Windows Defender.

Great. Thread marked as solved.

Follow the instructions below to cleanup the tool used in this thread.
Rename the file FRST64.exe to uninstall.exe and run it. This will remove all files and folders created by FRST and the tool itself.
Reboot the machine to complete.

Take care.
