Windows comes with built-in apps, services, and features that are designed to help you do more. Windows also provides experiences that connect to the internet to provide additional capabilities. These “connected experiences” can help you in various ways. For example, by allowing your device to keep track of your last known location, you have the ability to find your device if it’s lost or stolen.
When a connected experience is used, data is sent to and processed by Microsoft to provide that connected experience. This data is crucial because this information enables us to deliver these cloud-based connected experiences. We refer to this data as required service data. Required service data can include information related to the operation of the connected experience that is needed to keep the underlying service secure, up to date, and performing as expected. Required service data can also include information needed by a connected experience to perform its task, such as configuration information about Windows.
The connected experiences you choose to use in Windows will impact what required service data is sent to us.
Required service data is also collected and sent to Microsoft for essential services. Essential services are used to keep the product secure, up to date, and performing as expected, or they are integral to how the product works. For example, Windows Update is an essential service that ensures you have the latest updates to keep your device secure, up to date, and working as expected. Because these services are essential, you will not be able to turn them off.
The following list describes the essential services and connected experiences that are available to you in Windows and provides links to further information about each one.
Note: The information in this article describes the most common essential services and connected experiences. To reflect ongoing improvements to these experiences, the following list may be updated occasionally.
Essential services for Windows
|
Essential service |
Description |
|---|---|
|
Authentication |
The authentication service is required for you to sign in to your Microsoft account. It validates your Microsoft identity and provides access to multiple apps and features like OneDrive and Find my device. By allowing you to sign in to Windows with your Microsoft account, the authentication service enables Microsoft to provide a consistent experience across your devices. |
|
Certificates |
Certificates are digital files that are stored on your device and used to both encrypt data and verify the identity of an individual or organization.
If automatic updates are turned off, apps 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. |
|
Configuration Service |
Configuration Service is used as a way for OS components and apps to dynamically update their configuration. Apps such as System Initiated User Feedback and the Xbox app use it. |
|
Licensing |
The licensing service is used for online activation of Windows and licensing of apps purchased from the Microsoft Store. |
|
Networking |
The networking service in Windows allows you to connect your device to the local intranet and internet. |
|
Device setup |
The first time you set up a new device, Windows guides you through the steps to accept the license agreement, connect to the internet, sign in to (or sign up for) a Microsoft account, and take care of other important setup tasks. Most settings can also be changed after setup is completed. |
|
Diagnostic data |
Microsoft collects diagnostic data and 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. This data helps us understand how Windows behaves in the real world, focus on user priorities, find and fix problems, and improve services. Sharing this data allows us to make informed decisions that benefit all our customers. Learn more about diagnostics, feedback, and privacy in Windows |

|
Delivery Optimization |
Delivery Optimization is used to download Windows updates, Microsoft Store apps, Office, and other content from Microsoft. Delivery Optimization can also download from sources outside of Microsoft, which helps when you have a limited or unreliable internet connection and can also help you reduce the amount of bandwidth needed to keep your device up to date. If you have the Delivery Optimization Peer-to-Peer option turned on, devices on your local network can share updates and apps with other devices on your local network, if you choose, or with devices on the internet. By default, devices running Windows will only use Delivery Optimization to send and receive updates for devices and apps on your local network. |

|
Location services |
When the Location setting for your device is turned on, the Microsoft location service will use a combination of information from the global positioning service (GPS), nearby wireless access points, cell towers, and your 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. Turning on the Location setting for your device allows certain Windows features to function properly, such as the ability to set the time zone automatically or to find a lost or stolen device. |

Connected experience |
Description |
|---|---|
|
ActiveX Filtering |
ActiveX controls are small apps that allow websites to provide content such as videos and games, and let you interact with controls like toolbars and stock tickers. However, these apps can sometimes malfunction, and in some cases, they might be used to collect information from your device, damage information on your device, install software on your device without your consent, or allow someone else to control your device remotely. ActiveX Filtering in Internet Explorer prevents sites from installing and using these apps. This can help keep you safe as you browse, but it can also cause websites to behave in unexpected ways. To further enhance security, Internet Explorer also allows you to block out-of-date ActiveX controls. |
