Start and taskbar layout

Enterprises have been able to apply customized Start and taskbar layouts to devices running Windows 10 Enterprise and Education. In Windows 10, version 1703, customized Start and taskbar layout can also be applied to Windows 10 Pro.

Previously, the customized taskbar could only be deployed using Group Policy or provisioning packages. Windows 10, version 1703, adds support for customized taskbars to MDM.

More MDM policy settings are available for Start and taskbar layout. New MDM policy settings include:

Cortana at work

Cortana is Microsoft’s personal digital assistant, who helps busy people get things done, even while at work. Cortana has powerful configuration options, optimized for your business. When your employees sign in with an Azure Active Directory (Azure AD) account, they can give Cortana access to their enterprise/work identity, while getting all the functionality Cortana provides to them outside of work.

Using Azure AD also means that you can remove an employee’s profile (for example, when an employee leaves your organization) while respecting Windows Information Protection (WIP) policies and ignoring enterprise content, such as emails, calendar items, and people lists that are marked as enterprise data.

For more info about Cortana at work, see Cortana integration in your business or enterprise



MBR2GPT.EXE is a new command-line tool available in Windows 10 version 1703 and later versions. MBR2GPT converts a disk from Master Boot Record (MBR) to GUID Partition Table (GPT) partition style without modifying or deleting data on the disk. The tool is designed to be run from a Windows Preinstallation Environment (Windows PE) command prompt, but can also be run from the full Windows 10 operating system (OS).

The GPT partition format is newer and enables the use of larger and more disk partitions. It also provides added data reliability, supports other partition types, and enables faster boot and shutdown speeds. If you convert the system disk on a computer from MBR to GPT, you must also configure the computer to boot in UEFI mode, so make sure that your device supports UEFI before attempting to convert the system disk.

Other security features of Windows 10 that are enabled when you boot in UEFI mode include: Secure Boot, Early Launch Anti-malware (ELAM) driver, Windows Trusted Boot, Measured Boot, Device Guard, Credential Guard, and BitLocker Network Unlock.

For details, see MBR2GPT.EXE.

By enrolling devices in Azure AD, you increase the visibility of feedback submitted by users in your organization, especially on features that support your specific business needs. For details, see Windows Insider Program for Business.

Optimize update delivery

With changes delivered in Windows 10, version 1703, express updates are now fully supported with Microsoft Configuration Manager, starting with version 1702 of Configuration Manager, and with other third-party updating and management products that implement this new functionality. This support is in addition to current Express support on Windows Update, Windows Update for Business and WSUS.


The above changes can be made available to Windows 10, version 1607, by installing the April 2017 cumulative update.

Delivery Optimization policies now enable you to configure more restrictions to have more control in various scenarios.

Added policies include:

To check out all the details, see Configure Delivery Optimization for Windows 10 updates

Uninstalled in-box apps no longer automatically reinstall

Starting with Windows 10, version 1703, in-box apps that were uninstalled by the user won't automatically reinstall as part of the feature update installation process.

Additionally, apps de-provisioned by admins on Windows 10, version 1703 machines will stay de-provisioned after future feature update installations. This condition won't apply to the update from Windows 10, version 1607 (or earlier) to version 1703.


New MDM capabilities

Windows 10, version 1703 adds many new configuration service providers (CSPs) that provide new capabilities for managing Windows 10 devices using MDM or provisioning packages. Among other things, these CSPs enable you to configure a few hundred of the most useful Group Policy settings via MDM - see Policy CSP - ADMX-backed policies.

Some of the other new CSPs are:

  • The DynamicManagement CSP allows you to manage devices differently depending on location, network, or time. For example, managed devices can have cameras disabled when at a work location, the cellular service can be disabled when outside the country/region to avoid roaming charges, or the wireless network can be disabled when the device isn't within the corporate building or campus. Once configured, these settings will be enforced even if the device can’t reach the management server when the location or network changes. The Dynamic Management CSP enables configuration of policies that change how the device is managed in addition to setting the conditions on which the change occurs.

  • The CleanPC CSP allows removal of user-installed and pre-installed applications, with the option to persist user data.

  • The BitLocker CSP is used to manage encryption of PCs and devices. For example, you can require storage card encryption on mobile devices, or require encryption for operating system drives.

  • The NetworkProxy CSP is used to configure a proxy server for ethernet and Wi-Fi connections.

  • The Office CSP enables a Microsoft Office client to be installed on a device via the Office Deployment Tool. For more information, see Configuration options for the Office Deployment Tool.

  • The EnterpriseAppVManagement CSP is used to manage virtual applications in Windows 10 PCs (Enterprise and Education editions) and enables App-V sequenced apps to be streamed to PCs even when managed by MDM.

Mobile application management support for Windows 10

The Windows version of mobile application management (MAM) is a lightweight solution for managing company data access and security on personal devices. MAM support is built into Windows on top of Windows Information Protection (WIP), starting in Windows 10, version 1703.

For more info, see Implement server-side support for mobile application management on Windows.

MDM diagnostics

In Windows 10, version 1703, we continue our work to improve the diagnostic experience for modern management. By introducing auto-logging for mobile devices, Windows will automatically collect logs when encountering an error in MDM, eliminating the need to have always-on logging for memory-constrained devices. Additionally, we're introducing Microsoft Message Analyzer as an extra tool to help Support personnel quickly reduce issues to their root cause, while saving time and cost.

Application Virtualization for Windows (App-V)

Previous versions of the Microsoft Application Virtualization Sequencer (App-V Sequencer) have required you to manually create your sequencing environment. Windows 10, version 1703 introduces two new PowerShell cmdlets, New-AppVSequencerVM and Connect-AppvSequencerVM, which automatically create your sequencing environment for you, including provisioning your virtual machine. Additionally, the App-V Sequencer has been updated to let you sequence or update multiple apps at the same time, while automatically capturing and storing your customizations as an App-V project template (.appvt) file, and letting you use PowerShell or Group Policy settings to automatically clean up your unpublished packages after a device restart.

Miracast on existing wireless network or LAN

In the Windows 10, version 1703, Microsoft has extended the ability to send a Miracast stream over a local network rather than over a direct wireless link. This functionality is based on the Miracast over Infrastructure Connection Establishment Protocol (MS-MICE).

Miracast over Infrastructure offers many benefits:

  • Windows automatically detects when sending the video stream over this path is applicable.
  • Windows will only choose this route if the connection is over Ethernet or a secure Wi-Fi network.
  • Users don't have to change how they connect to a Miracast receiver. They use the same UX as for standard Miracast connections.
  • No changes to current wireless drivers or PC hardware are required.
  • It works well with older wireless hardware that isn't optimized for Miracast over Wi-Fi Direct.
  • It uses an existing connection that reduces the time to connect and provides a stable stream.

How it works

Users attempt to connect to a Miracast receiver as they did previously. When the list of Miracast receivers is populated, Windows 10 will identify that the receiver is capable of supporting a connection over the infrastructure. When the user selects a Miracast receiver, Windows 10 will attempt to resolve the device's hostname via standard DNS, and via multicast DNS (mDNS). If the name isn't resolvable via either DNS method, Windows 10 will fall back to establishing the Miracast session using the standard Wi-Fi direct connection.

Enabling Miracast over Infrastructure

If you have a device that has been updated to Windows 10, version 1703, then you automatically have this new feature. To take advantage of it in your environment, you need to ensure the following requirements are true within your deployment:

  • The device (PC or Surface Hub) needs to be running Windows 10, version 1703.
  • A Windows PC or Surface Hub can act as a Miracast over Infrastructure receiver. A Windows device can act as a Miracast over Infrastructure source.
    • As a Miracast receiver, the PC or Surface Hub must be connected to your enterprise network via either Ethernet or a secure Wi-Fi connection (for example, using either WPA2-PSK or WPA2-Enterprise security). If the Hub is connected to an open Wi-Fi connection, Miracast over Infrastructure will disable itself.
    • As a Miracast source, the device must be connected to the same enterprise network via Ethernet or a secure Wi-Fi connection.
  • The DNS Hostname (device name) of the device needs to be resolvable via your DNS servers. You can achieve this resolution by either allowing your device to register automatically via Dynamic DNS, or by manually creating an A or AAAA record for the device's hostname.
  • Windows 10 PCs must be connected to the same enterprise network via Ethernet or a secure Wi-Fi connection.

It's important to note that Miracast over Infrastructure isn't a replacement for standard Miracast. Instead, the functionality is complementary, and provides an advantage to users who are part of the enterprise network. Users who are guests to a particular location and don’t have access to the enterprise network will continue to connect using the Wi-Fi Direct connection method.

The following new features aren't part of Windows 10, but help you make the most of it.

Upgrade Readiness

Upgrade Readiness helps you ensure that applications and drivers are ready for a Windows 10 upgrade. The solution provides up-to-date application and driver inventory, information about known issues, troubleshooting guidance, and per-device readiness and tracking details. The Upgrade Readiness tool moved from public preview to general availability on March 2, 2017.

The development of Upgrade Readiness has been heavily influenced by input from the community the development of new features is ongoing. To begin using Upgrade Readiness, add it to an existing Operation Management Suite (OMS) workspace or sign up for a new OMS workspace with the Upgrade Readiness solution enabled.
