The authentication service is required to enable sign in to work or school accounts. It validates a user’s identity and provides access to multiple apps and system components like OneDrive and activity history. Using a work or school account to sign in to Windows 10 enables Microsoft to provide a consistent experience across your devices. If the authentication service is turned off, many apps and components may lose functionality and users may not be able to sign in.

Certificates are digital files, stored on client devices, used to both encrypt data and verify the identity of an individual or organization. Trusted root certificates issued by a certification authority (CA), are stored in a certificate trust list (CTL). The Automatic Root Certificates Update mechanism contacts Windows Updates to update the CTL. If a new version of the CTL is identified, the list of trusted root certificates cached on the local device will be updated. Untrusted certificates are certificates that are publicly known to be fraudulent. Untrusted certificates are also stored in a list on the local device and updated by the Automatic Root Certificates Update mechanism.
If automatic updates are turned off, applications and websites may stop working because they did not receive an updated root certificate that the application uses. Additionally, the list of untrusted certificates will no longer be updated, which increases the attack vector on the device.

Microsoft collects diagnostic data including error data about your device with the help of the telemetry service. Diagnostic data gives every user a voice in the operating system’s development and ongoing improvement. It helps us understand how Windows 10 behaves in the real world, focus on user priorities, find, and fix problems, and improve services. This data allows Microsoft to improve the Windows experience. Setting diagnostic data to off means important information to help fix issues and improve quality will not be available to Microsoft.

When Windows 10 detects a new device, it queries an online service called the Windows Metadata and Internet Services (WMIS) for a metadata package for the device. If a device metadata package is available on WMIS, the Device Metadata Retrieval Client (DMRC) that runs on the local device downloads and installs the package.

Delivery Optimization is a cloud-managed, peer-to-peer client and a downloader service for Windows updates, upgrades, and applications to an organization's networked devices. Delivery Optimization allows devices to download updates from alternate sources (such as other peers on the network), in addition to Microsoft servers. This helps when you have a limited or unreliable Internet connection and reduces the bandwidth needed to keep all your organization's devices up to date.
If you have Delivery Optimization Peer-to-Peer option turned on, devices on your network may send and receive updates and apps to other devices on your local network, if you choose, or to devices on the Internet.
By default, devices running Windows 10 will only use Delivery Optimization to get and receive updates for devices and apps on your local network.

The device location setting enables certain Windows features such as auto setting the time zone or Find My Device to function properly. When the device location setting is enabled, the Microsoft location service will use a combination of global positioning service (GPS), nearby wireless access points, cell towers, and IP address to determine the device’s location. Depending on the capabilities of the device, its location can be determined with varying degrees of accuracy and may in some cases be determined precisely.
