      Get-AppxPackage -AllUsers Microsoft.WindowsCalculator | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

    • Press Enter, and PowerShell will reinstall the Calculator app.
  4. Check Installation:

    • Once the installation is complete, you can check if the Calculator is back by searching for it in the Start menu.

Method 3: Use a Third-Party Calculator App

If the built-in Windows 10 Calculator is not working for you and you'd prefer to try an alternative, there are several third-party calculator apps available in the Microsoft Store or online. Some popular options include:

  • Calculator²: A free app that offers standard, scientific, and programmer modes.

  • NCalc: An advanced open-source calculator for more technical users.

You can install these apps directly from the Microsoft Store or download them from reputable websites. Just be sure to verify the source to avoid any potential malware.
