How to Fix “Windows 11 Unable to Stop Device” Error with Easy Solutions

Sometimes, when you try to safely remove a USB device or external hardware, Windows 11 shows an error saying it is unable to stop the device. This can be frustrating, especially if you want to unplug your device without risking data loss.

This error usually happens because some programs or system processes are still using the device. Luckily, there are easy ways to fix this issue and safely remove your hardware.

In this article, you will learn simple and detailed steps to resolve the “Unable to Stop Device” error on Windows 11. These solutions are designed for users of all levels, so take your time and follow along.

Let’s get started with some quick checks before moving on to the troubleshooting steps.

Quick Note: Prerequisites and Checks

  • Close all files and programs: Make sure no files or applications are open from the device you want to remove. Programs like Word, Excel, or video players might still be accessing the device.
  • Check background processes: Some apps run in the background and might use the device. Closing these can help.
  • Save your work: Always save any important data before trying to remove hardware to prevent data loss.
  • Use the Safely Remove Hardware icon: Always try to eject devices using the system tray icon instead of unplugging directly.

Step 1: Close Programs and Background Apps

The most common reason for this error is that some programs are still using the device. To fix this, try closing all opened files or apps related to the device.

  1. Look at your taskbar and system tray for any open applications.
  2. Right-click on the app and select Close or Exit.
  3. If unsure, open Task Manager by pressing Ctrl + Shift + Esc.
  4. In Task Manager, under the Processes tab, look for applications or processes that might be using the device.
  5. Select the process and click End Task.

Why this matters: If any app is actively using the device, Windows will prevent you from safely removing it to avoid data corruption.

Step 2: Use Device Manager to Disable the Device

If closing programs doesn’t work, you can disable the device temporarily using Device Manager. This will stop the device and allow safe removal.

  1. Press Windows + X and select Device Manager from the menu.
  2. Find your device under the relevant category (for example, under Universal Serial Bus controllers or Disk Drives).
  3. Right-click the device and choose Disable device.
  4. You will receive a warning; click Yes to confirm.
  5. Once disabled, try removing the device safely.
  6. After removal, go back to Device Manager and Enable the device if needed.

Why this helps: Disabling the device ensures Windows stops accessing it, which should clear the “unable to stop device” error.

Step 3: Restart Windows Explorer

Sometimes Windows Explorer holds on to files from your device. Restarting it can free the device for safe removal.

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. In the Processes tab, find Windows Explorer.
  3. Right-click it and select Restart.
  4. After Explorer restarts, try ejecting the device again.

Why restart Explorer? Windows Explorer handles file browsing and device management. Restarting it clears some locks on devices.

Step 4: Use Command Prompt to Force Remove Device

If the above methods fail, you can use the Command Prompt to safely stop the device.

  1. Press Windows + S, type cmd, right-click Command Prompt, and select Run as administrator.
  2. Type the following command and press Enter:
    3. diskpart
  3. Then type:
    4. list volume
  4. Look for your external device by its volume label or size.
  5. Type the following replacing # with the volume number of your device:
    6. select volume #
  6. Finally, type:
    7. remove letter=X

    (Replace X with the drive letter of your device.)

  7. This will safely remove the drive letter and stop Windows from accessing it.
  8. Close Command Prompt and unplug the device.

Why use this method? It forces Windows to dismount the device safely, allowing removal without errors.

Alternative Method: Use Third-Party Tools

There are reliable third-party utilities such as USB Safely Remove or Unlocker that can help you identify what is using the device and safely eject it.

  • These tools show detailed information about locked files or processes.
  • They often provide options to close or unlock these processes automatically.
  • Use these tools if you frequently experience this issue or want more control.

FAQs

Why does Windows say “Unable to Stop Device”?

Because some program or process is still accessing the device, Windows blocks the removal to prevent data loss or corruption.

Can I just unplug the device despite the error?

It is not recommended. Unplugging without safely ejecting can cause file corruption or damage the device.

Is it safe to disable the device in Device Manager?

Yes, disabling the device temporarily stops Windows from using it and is safe. Just remember to enable it afterward if needed.

What if the device is still in use after restarting Explorer?

Try closing any other apps or use Task Manager to check for hidden background processes using the device.

Can antivirus or security software cause this issue?

Yes, some security programs scan external devices and keep them busy. Temporarily disabling such software might help.

When Nothing Works

If none of the above solutions fix the problem, consider these final options:

  • Restart your computer: A fresh start often clears locked processes.
  • Check for Windows updates: Updates may fix bugs related to device management.
  • Visit Microsoft’s official support site: support.microsoft.com for advanced help.
  • Backup important data: As a precaution, back up files from the device regularly.

Conclusion

The “Unable to Stop Device” error in Windows 11 is common but usually easy to fix. Most of the time, simply closing apps or restarting Explorer solves the problem.

If that doesn’t work, disabling the device or using Command Prompt commands can help safely remove the device without risk.

Remember, always safely eject hardware to protect your data and device. If you face persistent issues, using third-party tools or restarting your PC can provide a reliable fix.

By following these simple and detailed steps, you can enjoy smooth and safe device removal on your Windows 11 system.
