Settings app is one of the most important features of Windows 10, because you basically control the whole system with it. And if this app stops working, a serious problem can occur. Unfortunately, this is exactly what happened to some Windows 10 users, but we’ll try to help them with a couple of solutions in this article.

Here are some more examples of similar issues you can resolve with the same solutions:

  • Windows 10 Settings app won’t open – The most common issue with the Settings app in Windows 10 is when you just click the icon, but nothing happens.
  • Windows 10 Settings app missing – In some cases, you won’t be able to even locate the Settings app icon, as it completely disappeared from the Start Menu.
  • Windows 10 Settings app crashes – Another common issue is when you’re actually able to open the Settings app, but it crashes immediately upon launch.
  • Windows 10 Settings grayed out – And the least common (but still possible) scenario is when the Settings app icon is just grayed out in the Start Menu.

What to do if the Settings app doesn’t work in Windows 10

Fix: Unable to launch Settings in Windows 10

Solution 1 – Download the troubleshooter

It looks like Microsoft is well-aware of this problem, so it released a proper troubleshooting tool for solving the problem with Windows 10 Settings app. Don’t worry, this troubleshooter will actually work on Windows 10, because it was made made specifically for Windows 10, so unlike many other troubleshooters you’ve already downloaded, which showed you an error because they weren’t compatible with Windows 10, this one will work just fine. So here’s exactly what you need to do:

  1. Download Settings troubleshooter from this link
  2. When asked, click on Run
  3. Follow instructions from the Wizard and let the troubleshooter find the solution

It will probably solve the problem with the Settings app, but even if it and other solutions from this article don’t solve the problem, you can try to run this same troubleshooter in a couple of days again. Because Microsoft said that it is working on even more solutions, which will be available soon.

Solution 2 – Manually download the fixing update

Along with the troubleshooter, Microsoft also released a cumulative update for Windows 10, which goes by the code of KB3081424. Reportedly, besides improving the system functionality, this update will also solve the Windows 10 Settings app problem. The update is available to download through Windows Update, but since Windows Update is a part of Windows 10 Settings app, you might be unable to receive it.

Luckily, Microsoft uploaded the update files on its website, so you can download the update manually. Just go to this link, download the update, install it and restart your computer. After that, open your Settings app and check if it’s working. The good thing about this update and fixes that it provides, is that it doesn’t restore the Settings app, so you won’t have to adjust your settings again, once you install the update.

Solution 3 – Run Sfc/scannow command

If these new troubleshooters for Settings app don’t work, you can always try with an old school problem-solver in Windows 10 (and all other Windows operating systems), Sfc/scannow command. This command will completely scan your computer for issues, and it will provide a suitable solution (if available). So, it will for sure cover the Settings app problem, and besides that it may solve some problems that you even didn’t know about.

Here’s what you need to do to run the sfc/scannow command:

  1. Right-click on the Start Menu button, and open Command Prompt (Admin)
  2. Enter the following line and press Enter: sfc/scannow
  3. Wait until the process is done (it may take a while)
  4. If the solution is found, it will automatically be applied
  5. Now, close the Command Prompt and restart your computer

Solution 4 – Use Command Prompt reinstall preinstalled apps

  1. Press Windows Key + X and choose Command Prompt (Admin) from the menu.
  2. Enter or paste this code: powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\ImmersiveControlPanel\AppxManifest.xml
  3. This process might take a while, so make sure that you wait until it’s finished.

Solution 5 – Uninstall OneKey Theater

This solution applies to Lenovo laptop users, so if don’t use Lenovo laptop skip this solution.

  1. Search for Control Panel and open it.
  2. Go to Programs/Uninstall a Program.
  3. On the list of installed programs find OneKey Theater, right click it and choose Uninstall.
  4. Your computer will now restart and this issue should be resolved.

Solution 6 – Run DISM

Deployment Image Servicing and Management (DISM) is another built-in troubleshooting tool. As its name says, DISM deploys the system image all over again, refreshing all the system features on the way. Including the Settings app.

Here’s how to run DISM in Windows 10:

  1. Open the Command Prompt as shown above.
  2. Enter the following command and press Enter:
      • DISM.exe /Online /Cleanup-image /Restorehealth
  3. Wait for the process to finish.
  4. Restart your computer.
  5. In case the DISM can’t obtain files online, try using your installation USB or DVD. Insert media and type following command:
      • DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess
  6. Make sure to replace ”C:\RepairSource\Windows” path of your DVD or USB.
  7. Follow further on-screen instructions.

Solution 7 – Update Windows

Microsoft usually releases patches and fixes for various system problems through Windows Update. But since we’re not able to access the Settings app, installing updates will be a little more complicated. So, the only solution you have in this case is to install the updates manually.

To install the latest Windows 10 updates manually, go to the Windows 10 update history page. Find the latest update for your version of Windows 10, and follow further instructions to download the update directly from the Windows Update catalog.

I hope that at least one of these solutions helped you to solve the problem with Settings app in Windows 10, if you have any other Windows 10-related issues you can check for the solution in our Windows 10 Fix section.
