Essential services and connected experiences for Windows

Applies to

  • Windows 11, version 21H2 and later
  • Windows 10, version 1903 and later

Windows includes features that connect to the internet to provide enhanced experiences and additional service-based capabilities. These features are called connected experiences. For example, Microsoft Defender Antivirus is a connected experience that delivers updated protection to keep the devices in your organization secure.

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, performing as expected or are integral to how the product works. For example, the licensing service that confirms that you’re properly licensed to use Windows.

Although enterprise admins can turn off most essential services, we recommend, where applicable, you consider hosting the services on-premises and carefully assess the impact of turning off remaining services. 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 connected experiences and essential services. We will continue to update our list of connected experiences over time as Windows evolves.

Windows essential services

Essential service Description
Authentication 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 Activity History. Using a work or school account to sign in to Windows 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.

To turn it off, see Microsoft Account.
Certificates 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 didn't 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.

To turn it off, see Automatic Root Certificates Update.
Device Management Device management includes Mobile Device Management (MDM), which helps IT pros manage company security policies and business applications. A built-in management component can communicate with the management server. If this is turned off, the device may no longer be compliant with company policy and the user might lose access to company resources.

Device setup The first time a user sets up a new device, the Windows out-of-box experience (OOBE) guides the user through the steps to accept the license agreement, connect to the internet, sign in to (or sign up for) a Microsoft account, and takes care of other important tasks. Most settings can also be changed after setup is completed.

To customize the initial setup experience, see Customize Setup.
Licensing Licensing services are used for the activation of Windows, and apps purchased from the Microsoft Store. If you disable the Windows License Manager Service or the Software Protection Platform Service, it may prevent activation of genuine Windows and store applications.

To turn off licensing services, see License Manager and Software Protection Platform.
Microsoft Store Microsoft Store enables users to purchase and download apps, games, and digital content. The Store also enables the developers of these apps to send toast, tile, badge, and raw updates from their own cloud service. This provides a mechanism to deliver new updates to store apps in a power-efficient and dependable way. The Store can also revoke malicious apps.

To turn it off, see Microsoft Store.
Networking Networking in Windows provides connectivity to and from your devices to the local intranet and internet. If you turn off networking, Windows devices will lose network connectivity.

To turn off Network Adapters, see Disable-NetAdapter.
Services Configuration Services Configuration is used by Windows components and apps, such as the telemetry service, to dynamically update their configuration. If you turn off this service, apps using this service may stop working.

To turn it off, see Services Configuration.
Update Windows Update ensures devices are kept up to date and secure by downloading the latest updates and security patches for Windows. This service also enables users to download apps from the Microsoft Store and keep them up to date. Turning off Windows Update will potentially leave your Windows devices in a vulnerable state and more prone to security threats.

Other services like Device metadata retrieval and Font streaming also ensure that the content on your devices is kept up to date.

To turn off updates, see Windows Update, Device metadata retrieval, and Font streaming.

To turn off specific connected experiences, see Internet Explorer.

Connected experience Description
Accelerators Accelerators are menu options in Internet Explorer that help automate common browser-related tasks. In Internet Explorer, when you right-click selected text, Accelerators appear in the list of available options.
For example, if you select a word, you can use the "Translate with Bing" Accelerator to obtain a translation of that word.
ActiveX Filtering ActiveX controls are small apps that allow websites to provide content such as videos and games, and let users 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 user devices, install software without a user's agreement, or be used to control a device remotely without a user's permission.
ActiveX Filtering in Internet Explorer prevents sites from installing and using these apps, which can help keep users safer as they browse, but it can also affect the user experience of certain sites as interactive content might not work when ActiveX Filtering is on.
Note: To further enhance security, Internet Explorer also allows you to block out-of-date ActiveX controls.
Address Bar and Search suggestions With search suggestions enabled, users will be offered suggested search terms as they type in the Address Bar. As users type information, it will be sent to the default search provider.
Auto-complete feature for web addresses The auto-complete feature suggests possible matches when users are typing web addresses in the browser address bar.
Compatibility logging This feature is designed for use by developers and IT professionals to determine the compatibility of their websites with Internet Explorer. It's disabled by default and needs to be enabled to start logging Internet Explorer events in the Windows Event Viewer. These events describe failures that might have happened on the site and can include information about specific controls and webpages that failed.
Compatibility View Compatibility View helps make websites designed for older browsers look better when viewed in Internet Explorer. The compatibility view setting allows you to choose whether an employee can fix website display problems they encounter while browsing.
Flip ahead Flip ahead enables users to flip through web content quickly by swiping across the page or by clicking forward. When flip ahead is turned on, web browsing history is periodically sent to Microsoft. If you turn off this setting, users will no longer be able swipe across a screen or click forward to go to the next pre-loaded page of a website.
Pinning websites to Start When a user pins a website to the Start menu, it displays as a tile similar to the way apps are displayed. Like Microsoft Store apps, website tiles might display updates if the website has been designed to do so. For example, an online email website might send updates to the tile indicating how many new messages a user has.
Suggested Sites Suggested Sites is an online experience that recommends websites, images, or videos a user might be interested in. When Suggested Sites is turned on, a user’s web browsing history is periodically sent to Microsoft.
Web Slices A Web Slice enables users to subscribe to and automatically receive updates to content directly within a web page. Disabling the RSS Feeds setting will turn off background synchronization for feeds and Web Slices.
