Reinstall Calculator

Reinstalling Calculator is something you should consider if the above two methods didnt work for you. The way to reinstall Calculator to fix Windows 10 Calculator not working is not a conventional one though. Other in-built Microsoft apps may have a direct uninstallation option, but Calculator doesnt. You can carry out this process in Windows PowerShell. First, you will have to uninstall the Calculator, then install it on your PC. Follow these steps:
Step 1: Open the Start menu, then search for PowerShell by typing Powershell. Now, right click on the Windows PowerShell option from the search result, then click Run as Administrator from the right-click menu.


Step 2: Now, enter the following piece of command in PowerShell and press Enter:

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

Running this command will re-register Windows Calculator on your PC.

This may take some time, so wait until the process is complete. Once done, go check if you have the Calculator app back on your PC. When found, simply run the Calculator and see if its working.
Alternative Step 3: If you do not want to re-install Calculator through Windows PowerShell, theres another way. As mentioned in Step 1 and Step 2 of Method #2, open the Microsoft App Store, find Calculator, and you will get the option to install Calculator from there. Its as simple as that.

If reinstalling Calculator didnt fix the Windows 10 Calculator not working issue on your PC, try the next method.


This issue may be caused due to damaged/corrupted Windows system files.

The sfc /scannow (System File Checker) command scans all protected system files, and replaces incorrect versions with correct Microsoft versions.

At the command prompt window, type the following commands:
Press the Enter key after each command:
