-# Windows 10 release information
-
-Feature updates for Windows 10 are released twice a year, targeting March and September, via the Semi-Annual Channel (SAC) and will be serviced with monthly quality updates for 18 months from the date of the release. We recommend that you begin deployment of each SAC release immediately to devices selected for early adoption and ramp up to full deployment at your discretion. This will enable you to gain access to new features, experiences, and integrated security as soon as possible.
-
-Starting with Windows 10, version 1809, feature updates for Windows 10 Enterprise and Education editions with a targeted release month of September will be serviced for 30 months from their release date. For information about servicing timelines, see the [Windows lifecycle fact sheet](https://support.microsoft.com/help/13853).
-
->[!NOTE]
->If you are not using Windows Update for Business today, the "Semi-Annual Channel (Targeted)" servicing option has no impact on when your devices will be updated. It merely reflects a milestone for the semi-annual release, the period of time during which Microsoft recommends that your IT team make the release available to specific, "targeted" devices for the purpose of validating and generating data in order to get to a broad deployment decision. For more information, see [this blog post](https://techcommunity.microsoft.com/t5/Windows-IT-Pro-Blog/Windows-Update-for-Business-and-the-retirement-of-SAC-T/ba-p/339523).

 Organizations should deploy more than one federation server in their federation farm for high-availability.

This largely depends on the number of devices and users using the services provided by the AD FS farm.

+## How WIP protects sensitivity labels with endpoint data loss prevention
+
+You can create and manage [sensitivity labels](https://docs.microsoft.com/office365/securitycompliance/labels) in the Microsoft 365 compliance center. 
+When you create a sensitivity label, you can specify that endpoint data loss prevention applies to content with that label. 
+
+![Endpoint data loss prevention](images/sensitivity-label-endpoint-dlp.png)
+
+Office app users can choose a sensitivity label from a menu and apply it to a file.
 
 ![Sensitivity labels](images/sensitivity-labels.png)
 
-## Default WIP behaviors for a sensitivity label
+WIP enforces default endpoint protection as follows: 
 
-Enterprises can create and manage sensitivity labels on the **Labels** page in the Office 365 Security & Compliance Center. 
-When you create a sensitivity label, you can specify that endpoint protection should apply to content with that label. 
-WIP enforces default endpoint protection depending on how the sensitivity label is configured:
+- If endpoint data loss prevention is enabled, the device enforces work protection for any file with the label
+- If endpoint data loss prevention is not enabled:
+  - The device enforces work protection to a file downloaded from a work site 
+  - The device does not enforce work protection to a file downloaded from a personal site
 
-- When the sensitivity label is configured for endpoint protection of content that includes business data, the device enforces work protection for documents with the label
-- When the sensitivity label is *not configured* for endpoint protection, the device reverts to whatever WIP policy has been defined in Intune or System Center Configuration Manager (SCCM):
-  - If the document is downloaded from a work site, the device enforces work protection
-  - If the document is downloaded from a personal site, no work protection is applied
-
-For more information about labels, see [Overview of labels](https://docs.microsoft.com/office365/securitycompliance/labels).
-
-## Use cases 
-
-This section covers how WIP works with sensitivity labels in specific use cases. 
-
-### User downloads from or creates a document on a work site
-
-If WIP policy is deployed, any document that is downloaded from a work site, or created on a work site, will have WIP protection regardless of whether the document has a sensitivity label.
-
-If the document also has a sensitivity label, which can be Office or PDF files, WIP protection is applied according to the label. 
-
-### User downloads a confidential Office or PDF document from a personal site 
-
-Windows Defender Advanced Threat Protection (Windows Defender ATP) scans for any file that gets modified or created, including files that were created on a personal site. 
-If the file has a sensitivity label, the corresponding WIP protection gets applied even though the file came from a personal site. 
-For example: 
+Here's an example where a file remains protected without any work context beyond the sensitivity label: 
 
 1. Sara creates a PDF file on a Mac and labels it as **Confidential**.
-2. She emails the PDF from her Gmail account to Laura.
-3. Laura opens the PDF file on her Windows 10 device. 
-4. WIP policy gets applied and the file is protected.
+1. She emails the PDF from her Gmail account to Laura.
+1. Laura opens the PDF file on her Windows 10 device. 
+1. Windows Defender Advanced Threat Protection (Windows Defender ATP) scans Windows 10 for any file that gets modified or created, including files that were created on a personal site. 
+1. Windows Defender ATP triggers WIP policy.
+1. WIP policy protects the file even though it came from a personal site.
 
-The PDF file doesn't need any work context beyond the sensitivity label. 
+## How WIP protects automatically classified files
+
+The next sections cover how Windows Defender ATP extends discovery and protection of sensitive information with improvements in Windows 10 version 1903. 
+
+### Discovery
+
+Windows Defender ATP can extract the content of the file itself and evaluate whether it contains sensitive information types such as credit card numbers or employee ID numbers. 
+When you create a sensitivity label, you can specify that the label be added to any file that contains a sensitive information type. 
+
+![Sensitivity labels](images/sensitivity-label-auto-label.png)
+
+A default set of [sensitive information types](https://docs.microsoft.com/office365/securitycompliance/what-the-sensitive-information-types-look-for) in Microsoft 365 compliance center includes credit card numbers, phone numbers, driver’s license numbers, and so on.
+You can also [create a custom sensitive information type](https://docs.microsoft.com/office365/securitycompliance/create-a-custom-sensitive-information-type), which can include any keyword or expression that you want to evaluate. 
+
+### Protection
+
+When a file is created or edited on a Windows 10 endpoint, Windows Defender ATP extracts the content and evaluates if it contains any default or custom sensitive information types that have been defined. 
+If the file has a match, Windows Defender ATP applies endpoint data loss prevention even if the file had no label previously. 
+
+Windows Defender ATP is integrated with Azure Information Protection for data discovery and reports sensitive information types that were discovered. 
+Azure Information Protection aggregates the files with sensitivity labels and the sensitive information types they contain across the enterprise. 
+
+![Image of Azure Information Protection - Data discovery](images/azure-data-discovery.png)
+
+You can see sensitive information types in Microsoft 365 compliance under **Classifications**. Default sensitive information types have Microsoft as the publisher. The publisher for custom types is the tenant name.
+
+![Sensitive information types](images/sensitive-info-types.png)
+
+>[!NOTE]
+>Automatic classification does not change the file itself, but it applies protection based on the label. 
+>WIP protects a file that contains a sensitive information type as a work file.
+>Azure Information Protection works differently in that it extends a file with a new attribute so the protection persists if the file is copied.
