    Windows Defender keeps closing some apps after a few seconds


    I already reinstalled windows 5 or 6 times, 23H2 and 24H2, installed the latest updates, both of them behaved the same way.The first problem is actually that windows defender keeps identifying almost everything as a threat!And when I add an exclusion on the main drive itself like on D drive, then apps keep getting closed!Then I stopped adding exclusions, I removed them, now after finding so many threats, it is now closing the apps again!I even tried removing Windows Defender using this tool but even after that, some apps just get closed automatically after a few seconds.I'm sure Windows Defend

    Unable to close Calculator app on Windows 10.

    Hi,

    To assist you better, I would like to ask if the issue persists with other Windows Apps as well.

    I suggest you to press/hold the left click button on the title bar of the calculator and drag the Windows to shrink the size of the Windows and check if the close (X) option appears. If the issue still persists, then suggest you to run the Windows Store
    Apps troubleshooter by following the steps provided below:

    • Type “Troubleshooting” in search box and press Enter.
    • Click on View all on top left pane.
    • Select “Windows Store Apps” from the list and follow the prompts for troubleshooting.

    Hope this helps. Keep us posted on the status for further assistance.

    Hi Tommy,

    Welcome to the Microsoft Community.


    • Is this issue specific to third party apps?
    I would suggest you to open Windows defender and add exclusions and check if it helps. Follow the steps to add exclusions in windows Defender.
