Policy CSP - Connectivity
Tip
This CSP contains ADMX-backed policies which require a special SyncML format to enable or disable. You must specify the data type in the SyncML as <Format>chr</Format>. For details, see Understanding ADMX-backed policies.
The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see CDATA Sections.
Important
This CSP contains some settings that are under development and only applicable for Windows Insider Preview builds. These settings are subject to change and may have dependencies on other features or services in preview.

This policy setting specifies whether to allow this client to download print driver packages over HTTP.
To set up HTTP printing, non-inbox drivers need to be downloaded over HTTP.
Note
This policy setting doesn't prevent the client from printing to printers on the Intranet or the Internet over HTTP. It only prohibits downloading drivers that aren't already installed locally.
If you enable this policy setting, print drivers can't be downloaded over HTTP.
If you disable or don't configure this policy setting, users can download print drivers over HTTP.

This policy setting specifies whether Windows should download a list of providers for the web publishing and online ordering wizards.
These wizards allow users to select from a list of companies that provide services such as online storage and photographic printing. By default, Windows displays providers downloaded from a Windows website in addition to providers specified in the registry.
If you enable this policy setting, Windows doesn't download providers, and only the service providers that are cached in the local registry are displayed.
If you disable or don't configure this policy setting, a list of providers are downloaded when the user uses the web publishing or online ordering wizards.
See the documentation for the web publishing and online ordering wizards for more information, including details on specifying service providers in the registry.

./Device/Vendor/MSFT/Policy/Config/Connectivity/DisallowNetworkConnectivityActiveTests
This policy setting turns off the active tests performed by the Windows Network Connectivity Status Indicator (NCSI) to determine whether your computer is connected to the Internet or to a more limited network.
As part of determining the connectivity level, NCSI performs one of two active tests: downloading a page from a dedicated Web server or making a DNS request for a dedicated address.
If you enable this policy setting, NCSI doesn't run either of the two active tests. This may reduce the ability of NCSI, and of other components that use NCSI, to determine Internet access.
If you disable or don't configure this policy setting, NCSI runs one of the two active tests.

If a computer is connected to a DNS domain network other than the one it was connected to when the setting was refreshed, this setting doesn't apply.
The Network Bridge allows users to create a layer 2 MAC bridge, enabling them to connect two or more network segements together. This connection appears in the Network Connections folder.
If you disable this setting or don't configure it, the user will be able to create and modify the configuration of a Network Bridge. Enabling this setting doesn't remove an existing Network Bridge from the user's computer.
