Auf meine Anfrage hin schrieb mir der Entwickler von WFC folgendes:
Hello Thomas. Please open the user manual by pressing F1 in any WFC window and read the following topic: User Interface > Main Panel > Security
In Windows, a software executed with administrative privileges can add, modify, remove Windows Firewall rules. Windows Firewall Control can prevent these external changes. When this feature is enabled, adding, modifying or importing firewall rules can be done only through the Windows Firewall Control user interface. This feature is automatically disabled when Windows Firewall Control is uninstalled.
When this feature is enabled:
• Windows Store will fail to install new apps because they will try register themselves in Windows Firewall, which will not be allowed.
• Adding, modifying or removing firewall rules through Windows Firewall with Advanced Security or command line will not work.
• If you see a notification from Windows Firewall when a new program tries to open a port, no matter what action you choose, "Allow access" or "Cancel", a new firewall rule will not be created.
• If you try to enable/disable certain operating system features through Control Panel, like Network Discovery, File and Printer Sharing, etc, nothing will happen.
The solution to the above scenarios is to define a global hot key for toggling Secure Rules in Options tab. Before performing any of the actions explained above, just quickly disable Secure Rules, perform your actions, then enable again Secure Rules by using the same global hot key. A confirmation dialog of the Secure Rules status will be displayed on screen.
If you prefer the old implementation of Secure Rules, version 220.127.116.11 can be downloaded from: https://www.binisoft.org/download/old/5 ... 5setup.exe
...und ich installiere Windows neu, spiele Images zurück und denke mein Windows ist beschädigt. Dabei waren es die "Geschützten Regeln" von WFC.
