Hello and welcome,

Follow the instructions below please.

WARNING! The following fix is specific to the user's system in this thread only. No one else should follow these instructions, as it could damage your system.

• Download
  
  SFCFix and move the executable to your desktop.
• Download the attachment SFCFix.zip and save it on your desktop.
• Save any work you have open, and close all programs.
• 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.
• Attach that file to your next reply.

Thanks, since this is a non-GUI Core install, I used the command

SFCFIX.exe SFCFIX.zip

and got this error:

 

[PeterJ]

SFCFIX.exe SFCFIX.zip

That doesn't work. Include the full pathname to the file SFCFix.zip, for example SFCFix C:\Users\<username>\Desktop\SFCFix.zip
Report the result.

 

[danrdj]

Same error. I opened the ZIP in File Explorer on another computer and it looks fine to me there.

 

[PeterJ]

Extract the file SFCFix.zip and provide the full pathname.

 

[danrdj]

Here's C:\Temp\SFCFix\


I don't know if it has anything to do with the fact that we're touching Defender files or not.
Here's the difference between the psd1 that's in the zip, and the currently installed psd1 file:


Does your source need to come from a Core installation?

Thanks!

Could I run SFCFix.exe from an adjacent server and specify the paths as \\badserver\c$\Temp\SFCFix.exe \\badserver\c$\Temp\SFCFix.zip or will SFCFix.exe do more "locally" on the machine it's running on, than just the operation explicit in the txt file?

 

[PeterJ]

Provide the full pathname to SFCFix.exe

 

[danrdj]

C:\Temp\SFCFix.exe

 

[PeterJ]

Open an elevated commandprompt window.
When command prompt opens, copy and paste the following commands into it, press enter after each.

CD C:\temp

SFCFix C:\temp\SFCFix.zip

Tell me if SFCFix runs fine or if it crashes again.

 

[danrdj]

If I run
SFCFix C:\temp\SFCFix.zip
then it crashes with something went horribly wrong

If I run
SFCFix.exe C:\temp\SFCFix.zip
then it gives ERROR: Zip file is corrupt or unreadable

 

[PeterJ]

Download the attachment SFCFixScript.txt and save it in the folder C:\temp.
Open an elevated commandprompt window.
When command prompt opens, copy and paste the following commands into it, press enter after each.

CD C:\temp

SFCFix.exe C:\temp\SFCFixScript.txt

Tell me if SFCFix runs fine or if it crashes again.

 

[danrdj]

I think it ran fine, just errored on logging?

Step 1:
Attach the file C:\temp\SFCFix.txt when available.

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.
