Troubleshooting the Windows Calculator

If you are experiencing problems with your Calculator app, you can choose any or all of the following solutions to bring it back to life.

Check for updates

The first approach should be to check for any pending updates, both in Windows Updates as well as the Microsoft Store. Any pending updates can cause an application to malfunction.

  1. Navigate to Start Menu -> Settings (Gear) Icon -> Update & Security
  2. Click on Check for updates and install any pending updates.
  3. Now navigate to the Microsoft store and click on the Pending updates button on the top-right corner. If you do not see this button, it means your applications are already up to date.
  4. Now click on Update all to begin updates for all Microsoft applications on your computer.
    get updates

Once all the applications have been updated, including Windows Calculator, relaunch the application and check if the error is resolved.

Running the System File Checker

Often Windows files are corrupted or accidentally deleted, which causes some of the apps to malfunction. A quick command can be used to rebuild those files and run the applications smoothly.

Open the Command Prompt by typing in cmd in Run.

Enter the following command:
sfc /scannow

The command will take a while to execute completely. When done, recheck if the Windows Calculator is functional now.

Running the Windows Troubleshooter

Windows Troubleshooter is a built-in utility in Windows 10 that can be used to resolve day-to-day errors experienced within the operating system. Lets see how this utility can be used to troubleshooter the Calculator.

Navigate to the following:
Start Menu -> Settings (Gear) Icon -> Update & Security -> Troubleshoot -> Additional Troubleshooters

Now scroll to the bottom of the screen, click on Windows Store apps, and then Run the troubleshooter.

A new wizard will launch to automatically detect the problems of any Windows applications. Go through with the wizard and perform any necessary actions recommended by it. When completed, recheck the application for any errors.

Resetting the application

You can also try to reset the Windows Calculator application in order to restore its standard functionality. Note that this will erase all history within the application, and reset any changes made.

  1. Navigate to the following:
    Start Menu -> Settings (Gear) Icon -> Apps
  2. In the right pane, click on Calculator, and then Advanced options.
    advanced options
  3. Then scroll down and click on Reset. If confirmation is required, click on Reset again.

The application has now been reset and should be fully functional. If the error still persists, resort to the option down below.

Reinstalling Windows Calculator using PowerShell

If you find that the Windows Calculator is still not free of errors, or is malfunctioning, you can always get rid of it and reinstall the application.

Although it is possible to remove the application from the settings, it is better to use PowerShell as it removes all the related packages from the installation directory, making room for a fresh installation.

  1. Run PowerShell in Administrative mode.
  2. Enter the following command:
    Get-AppxPackage –AllUsers
    This command will display a long list of applications and their details.
  3. Right-click on the title bar, expand Edit, and then click on Find.
    find ps
  4. Now search for Microsoft.WindowsCalculator in the Name title, and note the name in front of PackageFullName by selecting it and then right-clicking on it to copy.
    package name
    In this example, the Package Full Name is Microsoft.WindowsCalculator_10.2007.1.0_x64__8wekyb3d8bbwe
  5. Now enter the following command in PowerShell and replace PackageFullName with the name you have copied from the PowerShell.
    Remove-AppxPackage PackageFullName
  6. Now that the application has been uninstalled from your computer, you can now install it by going to the Microsoft Store and following the method stated earlier in the article.
