Calculator Not Working on Windows 11 After Update KB5074828 Jan 30, 2026

Nothing happens when I click on Calculator. I tried repairing it, resetting it, reregistered via PowerShell, reinstalled it via Microsoft Store, ran sfc /scannow, updated Windows, and restarted the computer. Still nothing happens. Thank you for your help.

This worked beautifully, and taught me not to install the optional previews. I was able to reinstall the Windows calculator, which I'm happier with than the alternate I had installed recently, and have deleted the latter. Thank you, Estrella721, VERY VERY MUCH!

I understand that the preview update KB5074828 caused your Calculator to stop working and that you have already tried repairing, resetting, and reinstalling the Calculator app, but it is still not working.

Since KB5074828 is an optional preview update, you can safely skip it. I suggest uninstalling this update by following the guide here: https://support.microsoft.com/windows/how-to-uninstall-a-windows-update-c77b8f9b-e4dc-4e9f-a803-fdec12e59fb0#ID0EBF=Windows_11

Preview updates are test releases for the full version, which is typically rolled out on the second Tuesday of the following month.

Go to the Windows Update page and toggle "Get the latest updates as soon as they're available" to Off, then restart your computer.

This will prevent Windows from downloading optional updates and will only install the regular monthly updates.

I ended up installing a different calculator via the Microsoft store which solved my problem. Thank you.
