Windows 10 Toolkitco.exe Application Error message - what is this?

Hi This Wreckage. The screenshot confirms that ToolkitCo.exe is failing to start. Error 0xc0000142 means a DLL failed to initialize; it does not identify the underlying cause. I can’t reliably identify the program from its filename alone, so let’s check what it belongs to before disabling anything.

Identify the startup entry​

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click More details, if shown, then the Startup tab. This lists applications configured to launch when you sign in.
3. Look for ToolkitCo or an entry containing Toolkit. If you find one, right-click it and select Open file location.
4. Right-click the highlighted file and select Properties. Check Details for its product name and company, and Digital Signatures, if present, for the signer.
5. Reply with the file’s full folder path, product name and publisher, or screenshots of those details. If there is no matching startup entry, post a screenshot of the Startup tab instead.

Stopping the popup​

Once we confirm that the entry belongs to an optional application you don’t need at sign-in, the simplest workaround is to disable that specific startup entry, then restart. Task Manager supports Disable and Enable, so the change is reversible. This stops its automatic launch rather than repairing the application.
Leave it enabled until identified, particularly if it might handle backups or another function you rely on. No registry changes or file deletion are needed at this stage.

You can stop the popup by identifying what is launching ToolkitCo.exe rather than simply dismissing the error. Press Ctrl + Shift + Esc to open Task Manager and check the Startup tab for anything related to Toolkit or Dell. If you find a matching entry, right click it and choose Open file location, then check Properties to confirm its publisher before disabling it. If it is not listed there, check Settings > Apps > Startup and the Task Scheduler for a related entry. If it belongs to a Dell utility, you can update or reinstall that utility from Dell’s official support site. Avoid deleting the file or editing the registry until you know what it does. The error alone does not indicate a Windows system failure.

Thanks, @datawizard0103. Identifying the executable and its startup trigger before making changes is the right approach. One clarification: we haven’t established that ToolkitCo.exe belongs to Dell—having a Dell PC is not enough to make that connection.
@This Wreckage, if the problem remains, please share the file location, product name, and publisher from the checks above. If you find a scheduled task instead, share its Actions tab showing the executable it launches, leaving the task unchanged for now.
That will help us determine whether disabling an optional startup item is appropriate or whether the application needs repair.
