The most common reason is a broken app file or a problem in the computer’s settings after using system restore or resetting Windows. Now that you know the causes, let’s go through some practical steps to fix the issue. Restarting your computer is a good first step.

1. Re-register all Microsoft Apps

If your Microsoft apps are not working or are freezing, re-registering them can often resolve the problem. Follow these steps to re-register all Windows apps:

2. Run Windows Store Apps Troubleshooter

One of the easiest ways to fix issues with Microsoft apps is to use the Windows Store Apps Troubleshooter. This tool helps fix problems like damaged app cache files.

3. Update Calculator

If you haven’t updated your Calculator or other Microsoft apps in a while, this could be the cause of the issue. Updating can often resolve problems.

4. Reset Calculator

Windows provides built-in Reset and Repair options for Microsoft apps, which can help fix issues without uninstalling.

5. Reinstall Calculator

If your Calculator app still doesn’t work, it’s possible that some of its files are missing or corrupted. Reinstalling the app can fix this.

6. Update Your Windows

Running an outdated version of Windows can cause many issues. Keeping Windows updated helps everything run more smoothly.

7. Run System File Checker

System File Checker (SFC) is a built-in tool that scans and repairs corrupted system files. It can help fix problems that might be affecting the Calculator app. You can learn more about it here.

8. Run DISM Scan

DISM (Deployment Image Servicing and Management) is another useful tool for fixing deeper Windows problems, especially if SFC didn’t find or fix anything.

9. End Task the RuntimeBroker.exe Process

Some background processes can interfere with apps. According to some users, RuntimeBroker.exe has been known to cause issues with the Calculator app. Ending this task can sometimes fix the Calculator.

10. Create a Local Account

If none of the above methods work, you can try creating a new local user account. Sometimes, user profile problems can cause app issues. If this solves your problem, you can move all your data to the new account. For a detailed guide, check out How to Create a New User Account and Transfer all the Data to it.
