Allow all trusted apps to install

This policy setting allows you to manage the installation of trusted line-of-business (LOB) or developer-signed packaged Microsoft Store apps. If you enable this policy setting, you can install any LOB or developer-signed packaged Microsoft Store app (which must be signed with a certificate chain that can be successfully validated by the local computer). If you disable or do not configure this policy setting, you cannot install LOB or developer-signed packaged Microsoft Store apps.
