How to Fix Calculator Not Working on Windows 10/11?
The Calculator app on Windows 10 or 11 might not open, might only open for a moment and then close, or might not respond at all, especially after a Windows update or upgrade. This usually happens because the app’s files are damaged, some needed files are missing, or the Windows Store is not working right.

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:
- Press the Windows key and type Windows PowerShell in the search box.
- Right-click on Windows PowerShell and choose Run as administrator (or press Ctrl + Shift + Enter).
- When PowerShell opens, copy and paste the following command and press Enter:
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}
- Wait for the process to finish.
- Check if the Calculator app is working.
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.
