Reviewed by Calculator Editorial Team

The Windows 10 Calculator app is a useful built-in tool, but sometimes it may need to be reinstalled. This guide explains how to reinstall the Calculator without using the Microsoft Store, including methods for different Windows 10 versions and troubleshooting tips.

Why Reinstall the Calculator

There are several reasons why you might need to reinstall the Calculator app:

  • The app has crashed or stopped working
  • You want to reset the app to its default settings
  • The app is missing features or functions
  • You're experiencing performance issues with the app
  • You want to ensure you have the latest version of the app

Reinstalling the Calculator app will not affect your personal files or settings. The process is safe and will not delete any of your data.

Reinstallation Methods

There are several methods to reinstall the Calculator app without using the Microsoft Store. Choose the method that best fits your situation.

Method 1: Using PowerShell

  1. Press Windows Key + X and select "Windows PowerShell (Admin)" or "Windows Terminal (Admin)"
  2. Type the following command and press Enter:
    Get-AppxPackage *WindowsCalculator* | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
  3. Wait for the process to complete
  4. Restart your computer if prompted

Method 2: Using Command Prompt

  1. Press Windows Key + X and select "Command Prompt (Admin)"
  2. Type the following command and press Enter:
    powershell Get-AppxPackage *WindowsCalculator* | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
  3. Wait for the process to complete
  4. Restart your computer if prompted

Method 3: Using DISM

  1. Press Windows Key + X and select "Command Prompt (Admin)"
