Windows 10: App blocked for security reasons

In Windows 10, unlike previous versions of Windows, there are apps that you can install and run. You can find new apps in the Microsoft Store, which you access from your desktop. If the error "App was blocked for security reasons" is displayed when you open an app, this can have different causes.

This helps with the "App was blocked for security reasons" error

When you try to open an app in Windows 10, you may see the "App was blocked for security reasons" error. This message is always displayed when the operating system considers the app to be a threat or it could be malware.

1. First check with a suitable antivirus program whether the application is malware. If this is the case, uninstall the app and check your system.
2. If you trust the application and want to run it despite the message, this is only possible via a change in the registry.
3. For this, you must disable the user account control in the registry and re-enable it after starting the application. Letzteres ist gerade deshalb wichtig, weil Windows sonst die Anwendungen nicht mehr überprüft.
4. Taucht die Meldung bei einem Samsung-Drucktreiber auf, müssen Sie diesen erneut herunterladen und installieren.
5. Achten Sie immer auf die Adressleiste einer Webseite. An dieser können Sie erkennen, ob die Seite vertrauenswürdig ist.
