I keep getting this SettingsExtensionLauncher.exe-Application Error (0xc0000142)

I keep getting this SettingsExtensionLauncher.exe-Application Error (0xc0000142) pop-up. I don't recognize the .exe file and googling it isn't helping. I have my laptop shut down right now because I'm afraid it's a virus or something. Can someone let me know if it's dangerous?

My laptop is a Samsung Galaxy Book5 Pro 360 55110

Hi, I found a similar Galaxy Book 5 Settings issue that improved after restarting Samsung services. I’d try this first:

Press Ctrl + Shift + Esc >> Services >> search “Samsung”. For each Samsung service showing Running, right-click >> Restart, then check whether the popup returns.

The error alone doesn’t mean it’s a virus. Let me know the result, and I’ll follow up.

Hello thank you for your response. The pop up did not return after restarting the Samsung services. It hasn't shown up again at all since last night even after multiple systems restarts which is kinda what worries me. I can't find any file with that name in the file explorer and I don't see anything called that in the task manager either

That’s reassuring—staying clear through several restarts suggests restarting the services helped.

Task Manager only shows running processes. This component may run briefly, and its file may be inside a protected app folder, so not finding it doesn’t itself suggest a virus.

For reassurance, I’d run Windows Security >> Virus & threat protection >> Scan options >> Full scan >> Scan now.

If nothing is detected and everything works normally, I’d leave things as they are. Let me know the scan result, and I’ll follow up.

SettingsExtensionLauncher.exe on a Samsung Galaxy Book is most likely associated with Samsung’s settings utilities, so update or repair the Samsung software first; error 0xc0000142 means the program failed to start and does not, by itself, indicate a virus.

It is reasonable to turn the laptop back on. Do not delete the .exe file manually.

Verify that it is the Samsung component

Start Windows and dismiss the message with OK.
Open Task Manager by pressing Ctrl+Shift+Esc.
If SettingsExtensionLauncher.exe appears under Processes or Details, right-click it and select Open file location.
Right-click the file → Properties → Digital Signatures.
Check that:
- The location belongs to a Samsung application, commonly beneath Program Files or the protected WindowsApps folder.
- The signer is Samsung Electronics and Windows reports that the signature is valid.

If the file is in an unrelated location such as a temporary folder, has no valid signature, or Windows Security reports it as a threat, skip directly to the malware scan below.

Repair Samsung Settings

Open Start → Settings → Apps → Installed apps.
Find Samsung Settings or a similarly named Samsung settings/extension utility.
Select ⋯ → Advanced options → Repair.
Restart the laptop and check whether the popup returns.
If Repair is unavailable or does not work, return to the same page and select Reset. Microsoft documents Repair and Reset as the supported Windows 11 recovery options for malfunctioning apps.^1^

If the error remains, uninstall that Samsung utility from Settings → Apps → Installed apps, restart Windows, and reinstall the package for the exact Galaxy Book5 Pro 360 model from Samsung’s Galaxy Books Download Center.^2^

Also install pending updates under Settings → Windows Update → Check for updates, then restart.

If you remain concerned about malware

Run Microsoft Defender Offline:

Save any open work.
Open Windows Security → Virus & threat protection → Scan options.
Select Microsoft Defender Offline scan → Scan now.
The computer will restart and perform the scan outside the normal Windows session. This deeper scan can detect malware that may evade a regular scan.^3^

If repairing Samsung Settings does not resolve it

Repair Windows system files from Terminal (Admin) or Command Prompt (Run as administrator):

DISM.exe /Online /Cleanup-Image /RestoreHealth
sfc /scannow

Allow the first command to complete before running the second, wait until SFC reaches 100%, and restart Windows. Microsoft documents this order for repairing the Windows image and protected system files.^4^

If the executable has a valid Samsung signature but the error continues after reinstalling the Samsung package and repairing Windows, contact Samsung support because the failing component is then within its Galaxy Book utility stack.
