NOX is a program you can uninstall like any other—here's how to do it completely

NOX App Player is an Android emulator that lets you run mobile apps on your computer. If you no longer use it, you can remove it through Windows settings, but doing it thoroughly means also clearing out the leftover files it leaves behind. The fastest way is to uninstall through Control Panel, then delete the folder where NOX stores its data.

Most people find that the standard uninstall removes the program itself but leaves behind virtual machine files, app data, and settings folders. These can take up several gigabytes of space. A complete removal takes about five minutes and involves two separate steps.

Key Takeaways

  • Uninstall NOX through Control Panel or Settings, which removes the main program but not the data folders it created.
  • After uninstalling, manually delete the NOX data folder at C:\Users\[YourUsername]\AppData\Local\Nox or C:\Users\[YourUsername]\Nox, depending on your version.
  • You may need to show hidden files in Windows File Explorer to see the AppData folder where NOX stores virtual machine files.
  • Restarting your computer after uninstalling helps may support Windows releases any remaining NOX processes.

Uninstall NOX through Windows Settings

Open Windows Settings by pressing the Windows key and typing "Settings," then select the Settings app. Go to Apps in the left menu, then click Apps & features. Scroll down until you find NOX App Player in the list, click it once to select it, then click the Uninstall button that appears.

Windows will show you an uninstall dialog. Click Uninstall again to confirm. The program will remove itself, which usually takes one to two minutes. When it finishes, you'll see a message saying the uninstall was successful. Do not restart your computer yet—you still need to delete the data folders.

If you're using an older version of Windows, you can also uninstall through Control Panel. Press the Windows key, type "Control Panel," and open it. Click Programs and Features, find NOX App Player, click it, and select Uninstall. The process is the same.

Delete NOX data folders from your hard drive

After uninstalling, NOX leaves behind folders containing virtual machine files, app data, and settings. These can take up 2 to 5 gigabytes depending on how many apps you ran in NOX. To remove them, you need to access hidden folders in Windows File Explorer.

Open File Explorer and click the View tab at the top. Check the box next to Hidden items—this shows folders that Windows normally hides. Now navigate to C:\Users\[YourUsername]\AppData\Local, replacing [YourUsername] with your actual Windows username. Look for a folder named Nox or Nox_share and delete it by right-clicking and selecting Delete.

Some versions of NOX also create a folder directly in your user folder. Navigate to C:\Users\[YourUsername] and look for a folder called Nox. If it exists, delete it the same way. Empty your Recycle Bin afterward to permanently remove these files.

What to do if NOX won't uninstall

Occasionally NOX gets stuck and won't uninstall normally. This usually happens if the program is still running in the background. Restart your computer first—this closes any lingering NOX processes. After restart, try uninstalling again through Settings.

If it still won't uninstall, open Task Manager by pressing Ctrl+Shift+Esc and look for any process with "Nox" in the name. Right-click it and select End task, then try uninstalling again. If you still have trouble, you can manually delete the NOX installation folder at C:\Program Files\Nox or C:\Program Files (x86)\Nox, though this is less clean than using the uninstaller.

Freeing up disk space after removal

NOX virtual machines can consume several gigabytes. After you delete the NOX folders, you should see that space return to your available storage. To verify the uninstall was complete, open File Explorer and navigate to C:\Program Files or C:\Program Files (x86)—there should be no Nox folder remaining.

If you want to reclaim space when ready, you can also run Disk Cleanup. Press the Windows key, type "Disk Cleanup," and open it. Select your C: drive and click OK. Check the boxes next to items you want to remove (temporary files are safe to delete), then click Delete Files. This removes temporary files that programs leave behind.

Preventing NOX from reinstalling

If you downloaded NOX from a third-party website rather than directly from the NOX website, your computer may have picked up bundled software or browser toolbars. After uninstalling NOX, check your installed programs for anything unfamiliar. Open Settings, go to Apps & features, and look for programs you don't recognize. Uninstall anything suspicious.

You should also check your browser extensions. Open your browser settings and look at installed extensions—remove any you didn't deliberately add. If you want to avoid this in the future, read NOX only from the official NOX website, and always uncheck any boxes during installation that offer to install additional software.

Frequently Asked Questions

Will uninstalling NOX delete the apps I installed inside it?

Yes. When you delete the NOX data folders, you also delete every app you installed in the emulator, along with any data those apps stored. If you need to keep anything, export it before uninstalling. NOX has a backup feature in its settings menu if you need to save app data first.

How much space does NOX usually take up?

The NOX program itself is about 500 megabytes, but the virtual machine files and apps you install inside it can easily reach 2 to 5 gigabytes or more. The exact amount depends on how many apps you installed and how much data they stored.

Can I reinstall NOX later if I change my mind?

Yes. You can read and install NOX again anytime from the official website. Your previous apps and settings won't be there—you'll start fresh—but the program itself installs the same way it did originally.

What if I see NOX still running after I uninstalled it?

Open Task Manager (Ctrl+Shift+Esc), search for any process with "Nox" in the name, and end it. Then restart your computer. If NOX processes keep appearing, you may not have fully deleted the data folders—go back and make sure you deleted everything in AppData\Local\Nox and your user folder.
