How To Fix Windows Calculator If It's Not Working On Windows 10?

Windows Calculator is a software calculator included in all versions of Windows. By default, Windows Calculator runs in standard mode, which resembles a four-function calculator. More advanced functions are available in scientific mode including logarithms, numerical base conversions, some logical operators, operator precedence, radian, degree and gradian support as well as simple single-variable statistical functions. It does not provide support for user-defined functions, complex numbers, storage variables for intermediate results (other than the classic accumulator memory of pocket calculators), automated polar-cartesian coordinates conversion, or support for two-variables statistics.

Windows Calculator is a simple, useful application for everyday use. Some users, however, have reported problems that the calculator was not operating properly or stopped working completely. For example, not starting, not opening, crashing, etc. These problems are rare, but fortunately, can be resolved. In this guide, we present a number of possible solutions to fix Windows Calculator.

Run The SFC Scan

System File Checker is a Windows utility that allows users to scan for corruptions in system files and restore them. This guide describes how to run the System File Checker tool (SFC.exe) to scan system files and repair any missing or corrupted ones. If a Windows Resource Protection (WRP) file is missing or corrupted, Windows may not behave as expected. For example, some Windows functions might fail or Windows will crash. The "sfc scannow" option is one of several specific switches available for the sfc command, the Command Prompt command used to run System File Checker. To run Command Prompt, type "command prompt" in Search, right-click on "Command Prompt", and select "Run as administrator" from the drop-down menu to run it with administrator privileges. You must run an elevated Command Prompt to perform a SFC scan.

run the sfc scan step 1

In the Command Prompt window, type "sfc /scannow" and press Enter on your keyboard to execute this command. System File Checker will start and should take some time (about 15 minutes) to complete the scan. Wait for the scanning process to complete and restart your computer to see if you still have issues with the Windows Calculator application.

run the sfc scan step 2

If the SFC scan did not fix the problem with Windows Calculator, or for some reason you were unable to run the SFC scan, try to run the DISM scan and then try to run the SFC scan again.

DISM stands for Deployment Image Servicing and Management and is used to repair and prepare Windows images, including the Windows Recovery Environment, Windows Setup, and Windows PE. To run a DISM scan, open Command Prompt as administrator and type this command: "DISM /Online /Cleanup-Image /RestoreHealth". Press Enter on your keyboard to execute it.

Reinstall Windows Calculator

If resetting Windows Calculator does not fix the problem, you could try to reinstall it. Since you cannot do this in the usual way (such as you can with most other Windows apps), you will have to use a little bit advanced method to reinstall Windows Calculator. Go and download CCleaner from here first.

CCleaner is a small, effective utility for computers running Microsoft Windows that cleans 'junk' and issues that accumulate over time: temporary files, broken shortcuts, and other problems. It protects your privacy, cleans the browsing history and temporary Internet files, allowing you to be a more confident Internet user and less susceptible to identity theft. CCleaner can clean redundant files from various programs saving hard disk space, remove unneeded entries in Windows Registry, help you uninstall software, and select which programs start with Windows.

Open CCleaner when downloaded and click "Tools" on the left pane. Ensure that you are in the "Uninstall" section. Here, you will see a list of programs. Find "Calculator". Select it, and then click "Uninstall" to uninstall it from the Windows operating system.

To start troubleshooting, go to Settings and type "troubleshoot". Then, select "Troubleshoot" from the list.

Re-register Windows Calculator

This method includes re-registering not only Windows Calculator, but also other Windows 10 applications. For this option, use PowerShell and its commands.

PowerShell is a task automation and configuration management framework from Microsoft, consisting of a command-line shell and associated scripting language. In PowerShell, administrative tasks are generally performed by "cmdlets", which are specialized .NET classes implementing a particular operation. To open PowerShell on Windows 10, type "powershell" in Search and right-click on the "Windows PowerShell" result, select "Run as administrator" from the contextual menu. Alternatively, access PowerShell by right-clicking on the Start icon in Windows and select the "Windows PowerShell (Admin)" result.

re-register windows calculator step 1

Now copy the command "Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}" and paste it into the PowerShell window - simply right-click on the Powershell background and the command will appear on it. Press Enter to execute this command.

End RuntimeBroker Process

Runtime Broker process is created by Microsoft and is a core process in Windows 8 and Windows 10. Runtime Broker is a Windows process in Task Manager that helps to manage permissions on your PC for apps from Microsoft Store. Ending the RuntimeBroker process in Task Manager could help to fix problems with Windows Calculator. To end this process, go to Task Manager. You can access it by pressing Ctrl + Shift + Esc keys on your keyboard or by right-clicking on Start and selecting "Task Manager" from the contextual menu.

end runtime broker process

In Task Manager, scroll down to find "RuntimeBroker". An easier way to find it is to press "R" key on your keyboard and search through the processes that start with the letter R. You might be fortunate and reach RuntimeBroker on the first search. Right-click on in and select "End task" from the contextual menu, or click the "End task" button in the bottom-right corner.

Create New Account

Windows 10 has two types of local user accounts: Standard and Administrator. Standard users can perform all common daily tasks, such as run programs, browse the Web, check e-mail, stream movies, etc. If you wish to perform tasks that make major changes to the system (such as installing software, add/remove or change user accounts, or run elevated commands), you need an Administrator account. Creating a new administrator account is simple - just follow these steps:

Go to Settings and click "Accounts".

create new account step 1

In Account settings, find "Family & other" people on the left pane and select it. Click "Add someone else to this PC" to create a new account on Windows.

create new account step 2

You will be asked to enter the email address or phone number of the person you wish to add. To add a user without a Microsoft account, click "I don't have this person's sign-in information". If a window requesting how you want to open it appears, ignore it and click "I don't have this person's sign-in information".

create new account step 3

Now, click "Add a user without a Microsoft account".

create new account step 4

Complete the required fields and click "Next".

create new account step 5

Your new account will now be created. Select it and click "Change account type".

create new account step 6

You will be given two options: "Standard User" and "Administrator". Select "Administrator" (if you want to use administrator privileges) and click "OK".

create new account step 7

If switching to a new administrator account fixed the issue with Windows Calculator, move all personal files and folders to this new account and use this account from now on (you can delete the old account after you have moved your files).

We hope that one of these solutions helps you solve problems with Windows Calculator. If you still have problems, you could simply download a third-party calculator.
