If you're looking to remove the 3D Viewer app from your Windows 10 computer, PowerShell is a powerful tool that can help you accomplish this task. Follow these steps to uninstall the 3D Viewer using PowerShell:

1. Open PowerShell: To begin, you'll need to open PowerShell with administrative privileges. Right-click on the Start button and select 'Windows PowerShell (Admin)' from the menu.

2. Check for the 3D Viewer package: Once PowerShell is open, type the following command and press Enter to list all the packages related to the 3D Viewer:

```powershell

Get-AppxPackage *3dviewer*

```

3. Remove the 3D Viewer package: After running the command, you'll see a list of packages related to the 3D Viewer app. Look for the package name of the 3D Viewer and note it down. To remove the package, use the following command and replace 'PackageFullName' with the actual package name you found:

```powershell

Remove-AppxPackage -package 'PackageFullName'

```

4. Confirm the uninstallation: Once you've entered the command to remove the package, PowerShell will execute the uninstallation process. After it's finished, the 3D Viewer app should be completely removed from your Windows 10 computer.

5. Verify the removal: To ensure that the 3D Viewer has been successfully uninstalled, you can run the following command to check for any remaining traces of the app:

If the app no longer appears in the list of packages, it means that the 3D Viewer has been successfully removed from your system.
