Enable App Installer Allowed Sources

This policy controls additional sources allowed by the enterprise IT administrator.

If you do not configure this policy, users will be able to add or remove additional sources other than those configured by policy.

If you enable this policy, only the sources specified can be added or removed from the Windows Package Manager. The representation for each allowed source can be obtained from installed sources using 'winget source export'.

If you disable this policy, no additional sources can be configured for the Windows Package Manager.
