6 Methods to Repair the “Factor Not Discovered” Error on Home windows

When you start an app like Command Prompt, Microsoft Edge, File Explorer, or the Settings app in Windows, you sometimes get an "Item not found" error message. This error usually occurs due to damaged drivers or files, third party applications, or even a bad Windows update.

Because there are many causes of "Item Not Found" error, you need to determine the cause so that you can apply the correct solution. Below we've outlined a few ways you can fix this error.

1. Restart Explorer.exe

If starting File Explorer results in an "Item not found" error, restarting may be able to do the job. All you have to do is stop the Windows explorer.exe process and start it again.

To do this, press Ctrl + Shift + Esc to start the Task Manager. Go to Processes Tab and look for Windows Explorer. Right click on it and choose End task.

Once Windows Explorer disappears from the list of processes, try starting File Explorer again. You can do this by clicking File> Create New Task, tap explorer.exe in the text field and click on OK. Hopefully, you can now launch File Explorer without any problems.

2. Uninstall any current Windows updates

If this error occurred after a Windows update, the update could have installed a driver that is triggering the "Item not found" error. In that case, you will need to uninstall the latest update to restore your system to an earlier state where everything was working fine.

You can uninstall Windows updates from the Control Panel. Press Ctrl + R, Type steering, and press Enter to start the control panel. Click on Uninstall a program under the Programs Section (or navigate to Control Panel Programs Programs and Features). Select in the left pane Show installed updates.

This will open a new window called Installed updates. Here you will find all updates that have been installed on your system. Just select the one where you ran into the error after installing it (use the Installed on Column for reference if necessary). Right click on it and choose Uninstall.

When you're done, check if that resolved the error.

3. Uninstall Lenovo software

As strange as it sounds, even a manufacturer's program can cause problems. If an "Item Not Found" error occurs on a Lenovo PC and it has Lenovo CapOSD and / or OneKey Theater installed, chances are these programs are the culprit.

The simple solution is to uninstall these programs and see if that solves the problem. To uninstall it you need to use the Control Panel.

Press Ctrl + R, Type appwiz.cpl, and press Enter. This starts the Programs and functions Control Panel window.

Here you can see all the programs listed on your PC. Look for Lenovo CapOSD and OneKey Theater. Right click on it and choose Uninstall. When you're done, restart your PC and see if the problem has been resolved.

Sometimes a corrupted system file is the main culprit of Windows failure. Unfortunately, there is no realistic way to manually locate and repair a damaged system file.

Fortunately, the System File Checker (SFC) utility comes in handy for such jobs. The SFC utility checks for system integrity violations and automatically fixes any it finds.

Running the scan is pretty straightforward. Press Ctrl + R, Type cmd, and press Ctrl + Shift + Enter to launch an elevated command prompt. Then run the following command and sit back with a drink of your choice while the scan takes place:

sfc / scannow

If it finds damaged system files, it will automatically repair them. If it doesn't find any damaged files, it will tell you it doesn't. If the SFC doesn't find any corrupted system files or the problem persists, you can try the DISM tool.

The Deployment Image Servicing and Management (DISM) tool is another command line tool that helps scan and fix problems with the system image automatically. Here is the command you need to run:

DISM / Online / Cleanup-Image / RestoreHealth

The DISM tool then connects to Windows Update to replace damaged files, if it finds any. Note that if you find the command stuck in the process, just give it a few minutes and it will complete.

Once the process is complete, restart your PC and see if the "Item not found" error persists.

5. Use another application

If you haven't resolved the problem yet, try a workaround. If you have encountered this problem with a specific file type, it may be helpful to simply change the default application. For example, if you've set pictures to open in the Windows Photos app by default and you get an "Item not found" error when opening pictures, try another photo viewer.

You can choose a different app by simply right-clicking on the file and selecting Open with > Choose another appand select the new default app from the list. If you want to set it as the default, check the box next to it Always use this app to open .png files (Of course, the file extension differs depending on the file you are working with).

6. Perform a full reset on your PC

This is your last resort. If none of these fixes worked, a full PC reset can help. Resetting Windows will bring it back to mint condition, just like it was when it was first installed. Before doing a reset, however, make sure you back up your files as a reset will remove all installed programs and even some of your files.

As drastic as that sounds, a full reset will most likely fix the "Item Not Found" error. This is because resetting will return your Windows operating system to its original default state.

Back in your element

Hopefully one of these fixes got your Windows system the lost item and you can now open the app that you wanted to open.

Windows often run into errors that you have never heard of before. Since you sometimes don't have time to troubleshoot, consider using a Windows-specific repair tool that does a lot of the legwork for you so that you can save time troubleshooting.
