Fixing the error: Windows 10 Calculator is not installed

Windows Calculator is a pre-installed application available on every Windows desktop and laptop. It comes with several pre-installed apps by default, including Windows Store, 3D Builder, Maps, Camera, Calendar, Calculator, Microsoft Edge, Groove Music, and many others. Unfortunately, all of these apps can fail or become inoperable at any time.

Many Windows 10 users have reported problems with a corrupt calculator app. The app doesn’t open completely or doesn’t open, but suddenly freezes and closes automatically. This can happen due to Windows updates, driver issues, third-party software, and other issues. Fortunately, all of these problems can be solved fairly easily, and you can get back to computing.

While some people use them daily, others consider calculators and other applications useless and want to get rid of them to save hard drive space or speed up the device. However, contrary to what many users think, pre-installed apps don’t run constantly in the background, which means that they only load up the processor when the user manually launches the app.

In addition, apps such as Calendar or Calculator take up very little memory, so removing them will not permanently solve the lack of free space. If you are not going to use a pre-installed application, you can always remove it from the Start menu. However, it is not recommended to uninstall the default tools, as there is a risk of damaging some important system files or interrupting your Windows 10 installation.

Here's how to fix the "Windows 10 Calculator is not installed" error.

Use the following PowerShell command to reinstall Windows 10 calculator.

When Windows embedded applications are deleted, it is quite difficult to restore them because they are not easy to load or reinstall. However, it’s not impossible, and you can do it with the PowerShell command after running it with administrator privileges. This command will reinstall the Windows 10 calculator and should solve the problem.

  1. Open the PowerShell utility by right-clicking on the Start menu button and selecting Windows PowerShell (Admin) from the context menu.
  2. If at this point you see the command line instead of PowerShell, you can also look for it in the Start menu or in the search box next to it. This time, make sure you right-click on the first result and select Run as administrator.
  3. In the PowerShell console, type the command shown below, and be sure to press Enter after typing.
    get-app-expackage *Microsoft.WindowsCalculator* | remove-appackage
  4. Let this command do its job! It should take a few minutes to reinstall the Windows 10 Calculator app. Check to see if the calculator appears in the Windows Store, where you need to look for it and download it!
Activate the Windows Defender firewall.

Users reported that they were no longer able to download integrated Windows apps after uninstalling them. Oddly enough, the reason was that the Windows Defender firewall was disabled.
This may seem like an odd way to solve the problem, but you should try to enable the Windows Defender Firewall before attempting to solve the problem further.
Try it below!

  1. Open the Control Panel by searching for the utility using the Start button or by clicking the Search button or the Cortana button on the left side of the taskbar (bottom left corner of the screen).
  2. Once the Control Panel opens, change the display to Large or Small icons and scroll down to open the Windows Defender Firewall option.
  3. Click on it, and then select the Enable or Disable Windows Defender Firewall option from the menu on the left side of the window.
  4. Click on the radio button next to the “Disable Windows Defender Firewall (not recommended)” option next to the private and public network settings. Apply the changes you made and try to find the Windows 10 Calculator in the Windows Store. It should show up!
Resetting data

If you find that the Windows 10 Calculator app is missing from Windows, but you haven’t done anything to uninstall or uninstall it, it may still be there, but the problem is that it can’t show up on your computer. This problem can be solved quite simply: by completely resetting the application data. Follow the instructions we have prepared below to try this method!

  1. Open the Run utility using the Windows + R key combination on your keyboard (press these keys at the same time). In the new window, type “ms-settings:” without quotation marks and press OK to open the setup tool.
  2. You can also use the Windows + I shortcut to launch settings, or just click on the Start menu button and then the gear icon!
  3. In settings, click on Apps, and under Apps & Features you should see a list of installed apps. Find your calculator in the list, left-click its entry in the list, and click the Advanced Settings button that appears.
  4. Scroll down to the Reset section and click the Reset button. Confirm the dialog boxes that appear and wait for the process to complete.
  5. Check to see if the calculator appears on your computer!
Remove some registry keys

This is the best way to solve the problem if you find that several other Windows applications are missing or appear to be corrupted on your computer. If you remove some keys from the registry, Windows will reinstall them and they should be quickly available on your computer.
Follow these steps!

  1. Since you are about to edit a registry key, we recommend that you take a look at this article that we published to help you secure your registry and avoid other problems. However, everything will go well if you follow the steps carefully and correctly.
  2. Open the registry editor window by typing “regedit” in the search bar, the “Start” menu or the “Run” dialog box, which can be accessed with the Windows + R key combination.
    To access the next key in the registry, go to the left pane :
  3. Click on the PackageList button and make sure you select all the registry entries it contains by holding down the left mouse button and dragging the mouse over the list. Right-click the selection and select Delete from the pop-up menu that appears. Confirm the appearance of any dialog boxes or tooltips!
  4. You can now reboot your computer manually by clicking Start Menu >> Power Button >> Reboot and see if the calculator and other applications are back in place after a while. This will probably solve the problem immediately.
Performing an onsite update

If no other method can solve the problem, the easiest way to get rid of it is to perform an onsite update where all your files, settings, and installed programs are stored. Reinstalling multiple applications is expensive, but it can solve the problem painlessly, especially if you’re struggling with it on multiple PCs.

  1. Download the Media Creation Tool executable file from the Microsoft Web site and wait until the download completes. Double-click the downloaded file in the download folder named MediaCreationTool.exe to open the installation. Click “Accept” on the first screen.
  2. Select the “Update This PC Now” option by checking the appropriate checkbox, and click “Next” to continue.
    The tool will download some files, check for updates and scan your computer to make sure it is ready, so please be patient.
  3. Accept the license terms in the next window if you want to continue installing, and wait again to connect to Microsoft for updates (again).
  4. After that, you should already see the “Ready to install” screen, which lists the options “Install Windows” and “Save personal files and applications”. This option was automatically selected because you are already using Windows 10 and want to save everything.
  5. The installation should now continue, so you should update your computer after you complete the installation process and have the Calculator installed on your computer!
