Added in Windows 10, version 1703. Boolean policy setting that determines whether Windows is allowed to download fonts and font catalog data from an online font provider. If you enable this setting, Windows periodically queries an online font provider to determine whether a new font catalog is available. Windows may also download font data if needed to format or render text. If you disable this policy setting, Windows does not connect to an online font provider and only enumerates locally-installed fonts.
Supported values: - false - No traffic to fs.microsoft.com and only locally-installed fonts are available. - true (default) - There may be network traffic to fs.microsoft.com and downloadable fonts are available to apps that support them.
This MDM setting corresponds to the EnableFontProviders Group Policy setting. If both the Group Policy and the MDM settings are configured, the group policy setting takes precedence. If neither is configured, the behavior depends on a DisableFontProviders registry value. In server editions, this registry value is set to 1 by default, so the default behavior is false (disabled). In all other editions, the registry value is not set by default, so the default behavior is true (enabled).
This setting is used by lower-level components for text display and fond handling and has not direct effect on web browsers, which may download web fonts used in web content. > [!Note] > Reboot is required after setting the policy; alternatively you can stop and restart the FontCache service.
To verify if System/AllowFontProviders is set to true: - After a client machine is rebooted, check whether there is any network traffic from client machine to fs.microsoft.com. **System/AllowLocation**

Specifies whether to allow app access to the Location service.
The following list shows the supported values: - 0 – Force Location Off. All Location Privacy settings are toggled off and greyed out. Users cannot change the settings, and no apps are allowed access to the Location service, including Cortana and Search. - 1 (default) – Location service is allowed. The user has control and can change Location Privacy settings on or off. - 2 – Force Location On. All Location Privacy settings are toggled on and greyed out. Users cannot change the settings and all consent permissions will be automatically suppressed.
Most restricted value is 0.
While the policy is set to 0 (Force Location Off) or 2 (Force Location On), any Location service call from an app would trigger the value set by this policy.
When switching the policy back from 0 (Force Location Off) or 2 (Force Location On) to 1 (User Control), the app reverts to its original Location service setting.
For example, an app's original Location setting is Off. The administrator then sets the **AllowLocation** policy to 2 (Force Location On.) The Location service starts working for that app, overriding the original setting. Later, if the administrator switches the **AllowLocation** policy back to 1 (User Control), the app will revert to using its original setting of Off. **System/AllowStorageCard**

Allows you to specify the fully qualified domain name (FQDN) or IP address of a proxy server to forward Connected User Experiences and Telemetry requests. The format for this setting is *<server>:<port>*. The connection is made over a Secure Sockets Layer (SSL) connection. If the named proxy fails, or if there is no proxy specified when this policy is enabled, the Connected User Experiences and Telemetry data will not be transmitted and will remain on the local device.
If you disable or do not configure this policy setting, Connected User Experiences and Telemetry will go to Microsoft using the default proxy configuration.
