# Device update management

In the current device landscape of PC, tablets, phones, and IoT devices, the Mobile Device Management (MDM) solutions are becoming prevalent as a lightweight device management technology. In Windows 10, we are investing heavily in extending the management capabilities available to MDMs. One key feature we are adding is the ability for MDMs to keep devices up-to-date with the latest Microsoft Updates.

In particular, Windows 10 provides additional APIs to enable MDMs to:

-   Ensure machines stay up-to-date by configuring Automatic Update policies.
-   Test updates on a smaller set of machines before enterprise-wide rollout by configuring which updates are approved for a given device.
-   Get compliance status of managed devices so IT can easily understand which machines still need a particular security patch, or how up-to-date is a particular machine.

This topic provides MDM ISVs with the information they need to implement update management in Windows 10.

In Windows 10, the MDM protocol has been extended to better enable IT admins to manage updates. In particular, Windows has added configuration service providers (CSPs) that expose policies and actions for MDMs to:

-   Configure automatic update policies to ensure devices stay up-to-date.
-   Get device compliance information (the list of updates that are needed but not yet installed).
-   Specify a per-device update approval list, to ensure devices don’t install unapproved updates that have not been tested.
-   Approve EULAs on behalf of the end-user so update deployment can be automated even for updates with EULAs.

The OMA DM APIs for specifying update approvals and getting compliance status reference updates using an Update ID, which is a GUID that identifies a particular update. The MDM, of course, will want to expose IT-friendly information about the update (instead of a raw GUID), including the update’s title, description, KB, update type (for example, a security update or service pack). For more information, see [\[MS-WSUSSS\]: Windows Update Services: Server-Server Protocol](http://go.microsoft.com/fwlink/p/?LinkId=526707).
For more information about the CSPs, see [Update CSP](update-csp.md) and the update policy area of the [Policy CSP](policy-configuration-service-provider.md).

The following diagram provides a conceptual overview of how this works:

![mobile device update management](images/mdm-update-sync.png)

The diagram can be roughly divided into three areas:

-   The Device Management service syncs update information (title, description, applicability) from Microsoft Update using the Server-Server sync protocol (top of the diagram).
-   The Device Management service sets automatic update policies, obtains update compliance information, and sets approvals via OMA DM (left portion of the diagram).
-   The device gets updates from Microsoft Update using client/server protocol, but only downloads and installs updates that are both applicable to the device and approved by IT (right portion of the diagram).

## <a href="" id="gettingupdatemetadata"></a>Getting update metadata using the Server-Server sync protocol

The Microsoft Update Catalog is huge and contains many updates that are not needed by MDM-managed devices, including updates for legacy software (for example, updates to servers, down-level desktop operating systems, and legacy apps), and a large number of drivers. We recommend that the MDM use the Server-Server sync protocol to get update metadata for updates reported from the client.

This section describes how this is done. The following diagram shows the server-server sync protocol process.

![mdm server-server sync](images/deviceupdateprocess2.png)

MSDN provides much information about the Server-Server sync protocol. In particular:

-   It is a SOAP-based protocol, and you can get the WSDL in [Server Sync Web Service](http://go.microsoft.com/fwlink/p/?LinkId=526727). The WSDL can be used to generate calling proxies for many programming environments, which will simplify your development.
-   You can find code samples in [Protocol Examples](http://go.microsoft.com/fwlink/p/?LinkId=526720). The sample code shows raw SOAP commands, which can be used. Although it’s even simpler to make the call from a programming language like .NET (calling the WSDL-generated proxies). The stub generated by the Server Sync WSDL from the MSDN link above generates an incorrect binding URL. The binding URL should be set to https://sws.update.microsoft.com/ServerSyncWebService/serversyncwebservice.asmx.

Some important highlights:

-   The protocol has an authorization phase (calling GetAuthConfig, GetAuthorizationCookie, and GetCookie). In [Protocol Examples](http://go.microsoft.com/fwlink/p/?LinkId=526720), the **Sample 1: Authorization** code shows how this is done. Even though this is called the authorization phase, the protocol is completely open (no credentials are needed to run this phase of the protocol). This sequence of calls needs to be done to obtain a cookie for the main part of the sync protocol. As an optimization, you can cache the cookie and only call this sequence again if your cookie has expired.
-   The protocol allows the MDM to sync update metadata for a particular update by calling GetUpdateData. For more information, see [GetUpdateData](https://msdn.microsoft.com/library/dd304816.aspx) in MSDN. The LocURI to get the applicable updates with their revision Numbers is `<LocURI>./Vendor/MSFT/Update/InstallableUpdates?list=StructData</LocURI>`. Because not all updates are available via S2S sync, make sure you handle SOAP errors.
-   For mobile devices, you can either sync metadata for a particular update by calling GetUpdateData, or for a local on-premises solution, you can use WSUS and manually import the mobile updates from the Microsoft Update Catalog site. For more information, see [Process flow diagram and screenshots of server sync process](#process-flow-diagram-and-screenshots-of-server-sync-process).

> **Note**  On Microsoft Update, metadata for a given update gets modified over time (updating descriptive information, fixing bugs in applicability rules, localization changes, etc). Each time such a change is made that doesn’t affect the update itself, a new update revision is created. The identity of an update revision is a compound key containing both an UpdateID (GUID) and a RevisionNumber (int). The MDM should not expose the notion of an update revision to IT. Instead, for each UpdateID (GUID) the MDM should just keep the metadata for the later revision of that update (the one with the highest revision number).


## <a href="" id="examplesofupdatestructure"></a>Examples of update metadata XML structure and element descriptions

The response of the GetUpdateData call returns an array of ServerSyncUpdateData that contains the update metadata in the XmlUpdateBlob element. The schema of the update xml is available at [Protocol Examples](http://go.microsoft.com/fwlink/p/?LinkId=526720). Some of the key elements are described below:

-   **UpdateID** – The unique identifier for an update
-   **RevisionNumber** – Revision number for the update in case the update was modified.
-   **CreationDate** – the date on which this update was created.
-   **UpdateType** – The type of update which could include the following:
    -   **Detectoid** – if this update identity represents a compatibility logic
    -   **Category** – This could represent either of the following:
        -   A Product category the update belongs to. For example, Windows, MS office etc.
        -   The classification the update belongs to. For example, Drivers, security etc.
    -   **Software** – If the update is a software update.
    -   **Driver** – if the update is a driver update.
-   **LocalizedProperties** – represents the language the update is available in, title and description of the update. It has the following fields:
    -   **Language** – The language code identifier (LCID). For example, en or es.
    -   **Title** – Title of the update. For example, “Windows SharePoint Services 3.0 Service Pack 3 x64 Edition (KB2526305)”
    -   **Description** – Description of the update. For example, “Windows SharePoint Services 3.0 Service Pack 3 (KB2526305) provides the latest updates to Windows SharePoint Services 3.0. After you install this item, you may have to restart your computer. After you have installed this item, it cannot be removed.”
-   **KBArticleID** – The KB article number for this update that has details regarding the particular update. For example, <http://support.microsoft.com/kb/2902892>.

## <a href="" id="recommendedflow"></a>Recommended Flow for Using the Server-Server Sync Protocol

This section describes a possible algorithm for using the server-server sync protocol to pull in update metadata to the MDM.

First some background:

- If you have a multi-tenant MDM, the update metadata can be kept in a shared partition, since it is common to all tenants.
- A metadata sync service can then be implemented that periodically calls server-server sync to pull in metadata for the updates IT cares about.
- The MDM component that uses OMA DM to control devices (described in the next section) should send the metadata sync service the list of needed updates it gets from each client if those updates are not already known to the device.


The following procedure describes a basic algorithm for a metadata sync service:

-   Initialization, composed of the following:
    1.  Create an empty list of “needed update IDs to fault in”. This list will get updated by the MDM service component that uses OMA DM. We recommend not adding definition updates to this list, since those are temporary in nature (for example, Defender releases about 4 new definition updates per day, each of which is cumulative).
-   Sync periodically (we recommend once every 2 hours - no more than once/hour).
    1.  Implement the authorization phase of the protocol to get a cookie if you don’t already have a non-expired cookie. See **Sample 1: Authorization** in [Protocol Examples](http://go.microsoft.com/fwlink/p/?LinkId=526720).
    2.  Implement the metadata portion of the protocol (see **Sample 2: Metadata and Deployments Synchronization** in [Protocol Examples](http://go.microsoft.com/fwlink/p/?LinkId=526720)), and:
        -   Call GetUpdateData for all updates in the "needed update IDs to fault in" list if the update metadata has not already been pulled into the DB.
            -   If the update is a newer revision of an existing update (same UpdateID, higher revision number), replace the previous update metadata with the new one.
            -   Remove updates from the "needed update IDs to fault in" list once they have been brought in.

This provides an efficient way to pull in the information about the set of Microsoft Updates that IT needs to manage, so the information can be used in various update management scenarios. For example, at update approval time you can pull information so IT can see what updates they are approving, or for compliance reports to see what updates are needed but not yet installed.

## <a href="" id="managingupdates"></a>Managing updates using OMA DM

An MDM can manage updates via OMA DM. The details of how to use and integrate an MDM with the Windows OMA DM protocol, and how to enroll devices for MDM management, is documented the [Mobile device management](mobile-device-enrollment.md) topic. This section focuses on how to extend that integration to support update management. The key aspects of update management include the following:

-   Configure automatic update policies to ensure devices stay up-to-date.
-   Get device compliance information (the list of updates that are needed but not yet installed)
-   Specify a per-device update approval list to ensure devices don’t install unapproved updates that have not been tested.
-   Approve EULAs on behalf of the end-user so update deployment can be automated even for updates with EULAs

The following list describes a suggested model for applying updates.

1.  Have a "Test Group" and an "All Group".
2.  In the Test group, just let all updates flow.
3.  In the All Group, set up Quality Update deferral for 7 days and then Quality Updates will be auto approved after the 7 days.  Note that Definition Updates are excluded from Quality Update deferrals and will be auto approved when they are availible. This can be done by setting Update/DeferQualityUpdatesPeriodInDays to 7 and just letting updates flow after seven days or pushing Pause in case of issues.

Updates are configured using a combination of the [Update CSP](update-csp.md), and the update portion of the [Policy CSP](policy-configuration-service-provider.md). Please refer to these topics for details on configuring updates.

### Update policies

The enterprise IT can configure auto-update polices via OMA DM using the [Policy CSP](policy-configuration-service-provider.md) (this functionality is not supported in Windows 10 Mobile and Windows 10 Home). Here's the CSP diagram for the Update node in Policy CSP.

The following diagram shows the Update policies in a tree format.

<a href="" id="update-allowautoupdate"></a>**Update/AllowAutoUpdate**  
> [!NOTE]
> This policy is available on Windows 10 Pro, Windows 10 Enterprise, Windows 10 Education, and Windows 10 Mobile Enterprise


<p style="margin-left: 20px">Enables the IT admin to manage automatic update behavior to scan, download, and install updates.

<p style="margin-left: 20px">Supported operations are Get and Replace.

<p style="margin-left: 20px">The following list shows the supported values:

-   0 – Notify the user before downloading the update. This policy is used by the enterprise who wants to enable the end-users to manage data usage. With this option users are notified when there are updates that apply to the device and are ready for download. Users can download and install the updates from the Windows Update control panel.
-   1 – Auto install the update and then notify the user to schedule a device restart. Updates are downloaded automatically on non-metered networks and installed during "Automatic Maintenance" when the device is not in use and is not running on battery power. If automatic maintenance is unable to install updates for two days, Windows Update will install updates immediately. If the installation requires a restart, the end-user is prompted to schedule the restart time. The end-user has up to seven days to schedule the restart and after that, a restart of the device is forced. Enabling the end-user to control the start time reduces the risk of accidental data loss caused by applications that do not shutdown properly on restart.
-   2 (default) – Auto install and restart. Updates are downloaded automatically on non-metered networks and installed during "Automatic Maintenance" when the device is not in use and is not running on battery power. If automatic maintenance is unable to install updates for two days, Windows Update will install updates right away. If a restart is required, then the device is automatically restarted when the device is not actively being used. This is the default behavior for unmanaged devices. Devices are updated quickly, but it increases the risk of accidental data loss caused by an application that does not shutdown properly on restart.
-   3 – Auto install and restart at a specified time. The IT specifies the installation day and time. If no day and time are specified, the default is 3 AM daily. Automatic installation happens at this time and device restart happens after a 15-minute countdown. If the user is logged in when Windows is ready to restart, the user can interrupt the 15-minute countdown to delay the restart.
-   4 – Auto install and restart without end-user control. Updates are downloaded automatically on non-metered networks and installed during "Automatic Maintenance" when the device is not in use and is not running on battery power. If automatic maintenance is unable to install updates for two days, Windows Update will install updates right away. If a restart is required, then the device is automatically restarted when the device is not actively being used. This setting option also sets the end-user control panel to read-only.
-   5 – Turn off automatic updates.

> [!IMPORTANT]
> This option should be used only for systems under regulatory compliance, as you will not get security updates as well.
 

<p style="margin-left: 20px">If the policy is not configured, end-users get the default behavior (Auto install and restart).

### Update management

The enterprise IT can configure the set of approved updates and get compliance status via OMA DM using the [Update CSP](update-csp.md). The following diagram shows the Update CSP in tree format..

![update csp diagram](images/provisioning-csp-update.png)

<a href="" id="update"></a>**Update**  
The root node.

Supported operation is Get.

<a href="" id="approvedupdates"></a>**ApprovedUpdates**  
Node for update approvals and EULA acceptance on behalf of the end-user.

> **Note** When the RequireUpdateApproval policy is set, the MDM uses the ApprovedUpdates list to pass the approved GUIDs. These GUIDs should be a subset of the InstallableUpdates list.

The MDM must first present the EULA to IT and have them accept it before the update is approved. Failure to do this is a breach of legal or contractual obligations. The EULAs can be obtained from the update metadata and have their own EULA ID. It's possible for multiple updates to share the same EULA. It is only necessary to approve the EULA once per EULA ID, not one per update.

The update approval list enables IT to approve individual updates and update classifications. Auto-approval by update classifications allows IT to automatically approve Definition Updates (i.e., updates to the virus and spyware definitions on devices) and Security Updates (i.e., product-specific updates for security-related vulnerability). The update approval list does not support the uninstallation of updates by revoking approval of already installed updates. Updates are approved based on UpdateID, and an UpdateID only needs to be approved once. An update UpdateID and RevisionNumber are part of the UpdateIdentity type. An UpdateID can be associated to several UpdateIdentity GUIDs due to changes to the RevisionNumber setting. MDM services must synchronize the UpdateIdentity of an UpdateID based on the latest RevisionNumber to get the latest metadata for an update. However, update approval is based on UpdateID.

> **Note**  For the Windows 10 build, the client may need to reboot after additional updates are added.

 

Supported operations are Get and Add.

<a href="" id="approvedupdates-approved-update-guid"></a>**ApprovedUpdates/****_Approved Update Guid_**  
Specifies the update GUID.

To auto-approve a class of updates, you can specify the [Update Classifications](http://go.microsoft.com/fwlink/p/?LinkId=526723) GUIDs. We strongly recommend to always specify the DefinitionsUpdates classification (E0789628-CE08-4437-BE74-2495B842F43B), which are used for anti-malware signatures. There are released periodically (several times a day). Some businesses may also want to auto-approve security updates to get them deployed quickly.

Supported operations are Get and Add.

Here is the list of older policies that are still supported for backward compatibility. You can use these for Windows 10, version 1511 devices.

-   Update/RequireDeferUpgrade
-   Update/DeferUpgradePeriod
-   Update/DeferUpdatePeriod
-   Update/PauseDeferrals

For Windows Update for Business, here is the list of supported policies on Windows 10 Mobile Enterprise:

-   For Windows 10, version 1511 (Build 10586): Update/RequireDeferUpgrade, Update/DeferUpdatePeriod and Update/PauseDeferrals. To use DeferUpdatePeriod and PauseDeferrals the RequireDeferUpgrade has to be set to 1, which essentially means for a device running 1511, the Windows Update for Business policies can only be set when a device is configured for CBB servicing.
-   For Windows 10, version 1607 (Build 14393): Update/BranchReadinessLevel, Update/DeferQualityUpdatesPeriodInDays and Update/PauseQualityUpdates. In 1607 we added support where you can configure Windows Update for Business policies when a device is configured for CB/CBB servicing.

> **Note**  
For policies supported for Windows Update for Business, when you set policies for both Windows 10, version 1607 and Windows 10, version 1511 running on 1607, then 1607 policies will be configured (1607 trumps 1511).

For policies supported for Windows Update for Business, when you set 1511 policies on a device running 1607, the you will get the expected behavior for 1511 policies.
