Read them one by one and check which one will be the most befitting to your case.

Solution #1: Re-registering Windows 10 Applications with PowerShell

There are occasions when Windows applications do not get properly registered or activated during the OS installation in the first place.

Thus re-registering the apps one more time can manually set the calculator to operation.

Here we will use the Windows 10 PowerShell to do the job.

Just read the contents below:

Step 1. In the Windows search box, type “PowerShell” and from the list of results, right-click on the PowerShell option.

Step 2. Select “Run as administrator” option from the context menu that follows.

Step 3. Now on the blue dialog box of PowerShell, copy and paste the following command and then hit “Enter” to execute it:

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

Wait patiently for a few minutes until the process is finished, and next check if the calculator is now working or not.

The command is most likely to re-register the Windows 10 app in which the calculator is also included.

Solution #2: Run an SFC Scan

Sometimes, your system files can get corrupted. Thus running a System File Checker (SFC) scanning can fix the issue very spontaneously.

To run the scan, we will make use Windows famous command-line interpreter CMD.

Read the steps below so that you can know the method better:

Step 1. Press “Win + X” and then choose “Command Prompt (Admin)” from the list of results that ensues.

The scanning process may take more than 15 minutes. So be patient while the process is active.

Once the scanning is done, now see if the calculator is still working or not.

Solution #3: Create a New User Account

If both the above-mentioned methods fail to set it right, then creating a new user account is the only viable option left to enable it.

Who knows, maybe the current user account that you are using has got some underlying issues which cannot be fixed.

So it is better to create a new account to get a fresh registration of Windows applications and utilities.

This is how you do it:

Step 1. Go to “Start” search box, and type “add user”.

Step 2. From the search result that follows, choose the “Add, Edit, or remove other users” option.

Step 6. Once you are done creating a new user account, log-in with it and check if the calculator is working or not.

If it seems to work with this new user account, then prefer to use the calculator always when signed in with this particular account, or you can delete the previous account. But make sure to copy your documents and files to this new user account.

Solution #4: Turn off the Firewall

Reports claim that if the Firewall is enabled in your system, which is mostly set to prevent certain programs from running, the calculator starts to malfunction.

Thus to disable the firewall, do the following:

Step 1. Press “Win + X” and type “Firewall”.

Step 2. Choose “Windows Firewall” from the list of option that shows up.
