Published by Nyau Wai Hoe - Updated on

If you’re a Windows user, chances are you rely on a few casual apps, such as the Microsoft Calculator app, for your daily calculation needs. However, if you’ve recently updated your Windows 10 or 11 system and find that the Calculator app is missing or not working, don’t worry – we’ve got you covered.

In this article, we will provide step-by-step instructions on how to troubleshoot and resolve issues with the Windows  Calculator app, ensuring that you can continue using it without any interruptions.

Windows 11/10 Calculator App Not Working

How to fix Calculator App not working issue in Windows 10 or 11

The Microsoft Calculator app comes pre-installed with your Windows 10 or 11 installation as bloatware. You can launch it by simply searching for it in the Start menu or Cortana. You can also pin it to your taskbar or create a shortcut on the desktop for easier access.

If you suddenly find that the Windows 10 or 11 Calculator app is missing from all these places, and you can’t even find it with Cortana, it could mean that it was accidentally removed or corrupted due to recent changes in your Windows system. Here’s what you can do to bring the Calculator app back to your Windows 10 or 11 system and fix the Calculator app not working issue.

Reset Calculator App in Windows 11/10

The first thing to try is to reset the Calculator app in Windows 10 or 11 entirely. By resetting the app, all of its settings will be reverted to its factory default, which may solve your Calculator app not working issue. Here’s how to reset it:

  1. Press Win+i to open the Settings app.
  2. Select Apps.
  3. From the left pane, select Apps & features.
  4. Now, on the right pane, scroll down and look for Calculator from the list of apps.
  5. Select it, then click on Advanced options.Calculator App Missing in Windows 10/11
  6. In the Calculator settings window, under Reset, click on the Reset button.Reset Calculator app in Windows 10/11
  7. Restart your PC.

After rebooting your computer, retry launching the Calculator app in Windows 10 or 11 again and see if your problem is fixed.

    Reinstall Calculator app in Windows 10

    If you can’t see the Calculator app from the list of apps or the above method doesn’t work to solve your Windows 10 or 11 Calculator app not working or missing issue, try reinstalling the Calculator app using Windows PowerShell. Here’s how to do it:

    1. Go to the Start menu or Cortana and search for Windows PowerShell. Right-click it and select Run as administrator.
    2. In PowerShell, type the following command:
      Get-AppxPackage -Name Microsoft.WindowsCalculator

      This command is to show the Windows 10 or 11 Calculator app package info. We need the package full name in order to remove the Calculator app. From what you see in PowerShell, copy the entire line of PackageFullName.
      Reinstall Windows Calculator

    3. Next, type the following command with your version of PackageFullName. Do not copy the following command. Only use the Remove-AppxPackage command with the package full name you copied earlier:
      Remove-AppxPackage Microsoft.WindowsCalculator_10.1806.1821.0_x64__8wekyb3d8bbwe

      Uninstall Microsoft Calculator app

    After executing the command, the Windows 10 or 11 Calculator app should be uninstalled and removed from your PC entirely. Now, you will have to install it again from the Microsoft Store.

    1. Go to the Start menu. Search for Microsoft Store and open it.
    2. In the store, search for Windows Calculator. Select it and then click on the Get button to install the Windows 10 or 11 Calculator app. Alternatively, you can also try other Calculator apps developed by third parties by searching for “calculator” in the Microsoft Store.

    Download Calculator app for Windows

    This method should solve any issue with the Windows 10 or 11 Calculator app not working or missing problem.

    Reinstall all Windows 10 default apps

    We do not recommend this method as it will also wipe all other default apps in Windows 10 or 11 and reinstall them. If you can’t get the PackageFullName to remove only the Calculator app as guided above, or the command above just doesn’t work, here’s a universal command to reinstall all default apps in Windows 10 or 11 at once.

    Open Windows PowerShell with admin privileges as outlined above, and then enter the following command:

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

    Reinstall all Windows Default Apps

    The above command will reinstall all default apps, including the Calculator app, in Windows 10 or 11 for the current user account. If you want to reinstall all Windows apps for all accounts on your PC, run the following command instead:

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

    This method is known to be the most widely-used “fix all” option when users have issues with their Windows 10 or 11 default apps, such as the Calculator app not working or missing problem.

    In summary, if you’re facing issues with the Windows 10 or 11 Calculator app, try resetting it or reinstalling it using PowerShell. These methods should solve the issue for most users. However, if you’re still facing issues, you can always try reinstalling all default apps using PowerShell, although we recommend this as a last resort as it will also wipe all other default apps in your Windows 10 or 11 system.
