Windows 11 Calculator Not Working? How to Fix It

Windows 11 Calculator not working can be inconvenient when you need to make a quick calculation and the app refuses to open, freezes on launch or closes unexpectedly. Sometimes the Calculator window appears but does not respond to clicks, while in other cases the app opens and immediately crashes.

The problem may involve a temporary app glitch, outdated app files, corrupted app data or a Windows issue. Start with the simplest checks and move on to app repair only if necessary.

Fix 1: Close Calculator and Open It Again

A temporary application glitch may prevent Calculator from opening or responding correctly. Fully closing the app is a sensible first step.

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Find Calculator in the Processes list, if it appears.
3. Right-click it and select End task.
4. Open the Start menu and search for Calculator.
5. Launch the app and try a simple calculation.

If Calculator works normally after restarting it, the problem may have been temporary.

If it still freezes or closes immediately, continue to the next fix.

Fix 2: Restart Your Computer

If Calculator remains unresponsive, restart Windows before changing app settings.

1. Save your open work.
2. Press Ctrl + Alt + Delete.
3. Select the power icon.
4. Choose Restart.
5. Once Windows loads, open Calculator and test it again.

Restarting can resolve temporary system or app-process problems. If Calculator continues to fail after a restart, investigate the app itself.

Fix 3: Repair the Calculator App

Windows provides an app repair option that can fix certain problems without removing the app’s data.

1. Press Windows + I to open Settings.
2. Select Apps > Installed apps.
3. Search for Calculator.
4. Select the three-dot menu next to the app.
5. Choose Advanced options, if available.
6. Select Terminate if the app is still running.
7. Select Repair and wait for the process to finish.
8. Open Calculator and test it again.

The exact options may vary depending on your Windows version.

Repair is preferable to Reset as an initial step because it attempts to fix the app without clearing its local data.

If Calculator still does not work, move on to the next fix.

Fix 4: Reset Calculator if Repair Does Not Help

If repairing the app has no effect, resetting it may resolve more persistent app-data problems.

Before proceeding, understand that resetting can remove the app’s local data and settings.

1. Open Settings > Apps > Installed apps.
2. Find Calculator.
3. Select its three-dot menu and open Advanced options.
4. Select Reset, if available.
5. Confirm the action if Windows asks you to.
6. Open Calculator again and test it.

Resetting restores the app to its default state. It is different from repairing the app, so try Repair first.

If the Reset option is missing or the app continues to crash, check for updates.

Fix 5: Update Calculator Through Microsoft Store

An outdated or malfunctioning version of Calculator may cause launch problems or unexpected crashes.

1. Open Microsoft Store.
2. Select Library.
3. Choose Get updates.
4. Check whether an update for Windows Calculator is available.
5. Install it if offered.
6. Launch Calculator again.

If Microsoft Store cannot open, investigate that problem separately rather than downloading Calculator from an unfamiliar website.

Use Microsoft Store or other official Microsoft distribution channels to obtain app updates.

Fix 6: Check for Windows Updates

If Calculator still fails after the app-specific checks, install applicable Windows updates.

1. Open Settings > Windows Update.
2. Select Check for updates.
3. Install relevant updates.
4. Restart the computer if prompted.
5. Open Calculator and test it again.

If the problem started immediately after a particular update, note the update’s name and installation date. This information can help with further troubleshooting.

Avoid uninstalling updates without a clear reason. If several built-in Windows apps are failing, the underlying issue may affect Windows more broadly.

Fix 7: Check Whether Other Windows Apps Are Also Failing

If Calculator continues to crash, test another built-in Windows app, such as Notepad.

1. Open the Start menu and search for Notepad.
2. Launch it and check whether it opens normally.
3. If it works, return to Calculator and note the exact error or behavior.
4. If multiple built-in apps fail, investigate whether Windows has a wider app or system problem.

If other apps are also affected, you can consider running System File Checker to look for certain corrupted Windows system files.

To run the scan, open an elevated Command Prompt or Terminal and enter:

sfc /scannow

Wait for the scan to finish and review the result. If Windows reports that it repaired files, restart the computer and test Calculator again.

Do not assume that every Calculator problem is caused by damaged system files. If Calculator is the only app affected, continue focusing on its installation and app settings.

What If Calculator Still Does Not Work?

Use the symptoms to decide what to investigate next:

• Calculator opens but freezes: End the task and reopen the app.
• Calculator closes immediately: Try Repair, then Reset if necessary.
• Calculator is missing from the Start menu: Search for it in Installed apps and check Microsoft Store.
• Calculator works after a reset but later fails again: Check app updates and whether the problem follows a Windows update.
• Several built-in apps fail: Investigate a wider Windows issue rather than repeatedly resetting Calculator.

If you need to perform a calculation immediately, use another trusted calculator application or an available calculator tool while you troubleshoot. Avoid installing unknown software just to replace the built-in app.

Final Thoughts

When Windows 11 Calculator stops working, start by closing the app and restarting your computer. If the problem continues, use Windows’ Repair option before trying Reset.

Next, check Microsoft Store and Windows updates. If multiple built-in apps are failing, investigate a broader system problem. Working through these steps in order can help you identify the cause without making unnecessary changes to Windows.
