[QUOTE="Andy Ful, post: 1090539, member: 32260"] AppInstaller is a default app to run APPX and MSIX packages in Windows. Normally, it is triggered when the user tries to run the MSIX package from Explorer - this is an attack vector used in the wild (fake updates, etc.). The attacker can run MSIX packages without AppInstaller by using PowerShell. But, this attack vector is also prevented by disabling the AllowAllTrustedApps policy. I plan to add this restriction to Hard_Configurator and WHHLight. [/QUOTE]
