TECH LICENSING PROGRAMS
exFAT Exchange ActiveSync Server Message Block Remote Desktop Protocol Airband
PlayReady Windows Media Azure RTOS
EXFAT
Built to handle the demands of today’s digital media, exFAT enables seamless
file transfer and storage using permanent or removable media, regardless of
device or operating system.
Read our exFAT specification
Consumers and businesses are creating ever-increasing amounts of high-quality
photos, video, and other digital media. Once created, that media needs to be
stored and shared across multiple platforms and products. Cloud technologies can
facilitate the sharing process, but in many applications, there is no substitute
for the convenience of removable storage.
Extended File Allocation Table (exFAT) is Microsoft-patented file system. exFAT
can handle extremely large file sizes and enables seamless file exchange between
devices that use removable storage, regardless of device or operating system.
Combining wide interoperability with the capacity to handle files at virtually
unlimited scale, exFAT is a must-have tech licensing program for companies
seeking an efficient file storage and transfer solution.
HOW EXFAT WORKS
The exFAT file system handles large files, such as those used for audio and
video media. It allows efficient storage and seamless data portability between
desktop PCs and consumer electronic devices, enabling easy interchange between
the two. Inheriting its base from FAT32, another Microsoft file system, exFAT
can be implemented with minimal effort. Companies can also choose to add
transaction support to their exFAT implementation (TexFAT) to assist with
transaction-safe operations. exFAT has been included in Windows operating
systems since Windows CE 6.0 and Windows Vista SP1.
ENABLES VIRTUALLY UNLIMITED CARD STORAGE
exFAT allows devices to handle growing requirements for media file storage,
increasing volume capacity into the terabytes. exFAT also allows for single
files to exceed 4 GB, a limitation of FAT32.
PROVIDES AN EXTENSIBLE FORMAT
The extensible format includes OEM-definable parameters to customize the file
system for specific devices.
INTEROPERABILITY OF SYSTEMS AND DEVICES
exFAT supports interoperability with a very wide range of operating systems,
avoiding the need to constantly reformat files and media.
ENABLES FAST TRANSFER SPEEDS
With modern storage allocation techniques, file saves can achieve their full
speeds.
OUR EXFAT LICENSEES
More than 100 companies license exFAT, including some of the world’s best-known
and most innovative OEMs. exFAT is used by the Secure Digital (SD) Card
Association for high-capacity, high-speed SDXC and SDUC cards.
DIRECT LICENSE WITH EXFAT IMPLEMENTATION
Microsoft has agreements with several industry leaders that allow them to
provide exFAT implementations directly to customers along with a direct license
from Microsoft. These leaders can offer highly tuned implementations to provide
the best end-customer experience and include warranty and support. This offering
is available through the following companies:
PARAGON SOFTWARE GROUP

EXFAT AS PART OF THE LINUX KERNEL
In August 2019 Microsoft announced its support for integrating exFAT into the
Linux kernel. exFAT is now part of the Linux kernel 5.7 and devices using this
code are covered under the GPLv2 license.

EXCHANGE ACTIVESYNC (EAS)
Best-in-class, real-time syncing of email, contacts, calendars, and tasks on
mobile and tablet.
Read the EAS overview View the protocol documents
In the mobile era, consumer and business devices respond immediately to users’
gestures, their requests, and even their voices. Users expect that key
communications and productivity applications will be just as responsive, keeping
them up-to-date and organized in real time.
Microsoft Exchange ActiveSync (EAS) is a powerful communications protocol that
enables the syncing of email, calendars, contacts, and tasks on tablets and
mobile phones, pushing accurate, reliable data.
HOW EXCHANGE ACTIVESYNC WORKS
The Exchange ActiveSync protocol is the language spoken between a mobile device
or tablet and a messaging server, enabling synchronization of pre-defined
objects. The EAS protocol allows devices to synchronize email, calendar,
contacts, and tasks over the air with Microsoft Exchange, Outlook.com and other
servers which implement the protocol.
Syncing is the process of reconciling differences between data stored on a
device and on the Exchange Server. A mobile device or tablet will have its own
email, contacts, calendar, and task applications, maintaining its own collection
of objects and changes made since its last sync with the Exchange Server.
The device may initiate a new sync by sending a set of updates to the Exchange
Server and requesting the Exchange Server respond with its own updates. The
Exchange Server processes updates it receives, resolves any conflicts, and sends
its changes back to the mobile device.
OEMs, application developers and service providers can license Exchange
ActiveSync for use on their own devices, software, or servers.
BENEFITS OF EAS
COMPLETE SYNCING SOLUTION
EAS ensures seamless syncing of more than just email. EAS enables new contacts,
calendar appointments, and tasks to be updated instantly on all types of
devices. EAS also includes mobile device policies attractive to many businesses.
PUSH FUNCTIONALITY
EAS can push messages and calendar appointments to mobile devices and tablets as
soon as they become available, rather than fetching them from a server at fixed
intervals. As a result, EAS works in real time, delivering updates at the speed
consumers demand.
BROADLY LICENSED PROTOCOL
Many OEMs and software developers have licensed EAS. Many of the world’s most
widely used email clients adopt EAS to sync email and other data with top
messaging servers.

SERVER MESSAGE BLOCK (SMB)
A near-universal language for file transfers across local and virtual networks.
View the protocol documents
Modern area networks are often mixed environments that connect an array of
devices. Both homes and offices rely on networks that connect personal
computers, servers, mobile devices, and peripherals such as printers and
scanners.
HOW SMB WORKS
SMB is a client-server system. It provides a protocol for exchanging data
packets between the client device and the server. Data packets may control
sessions with the server, allow users to remotely access and edit files and
directories stored on the server, and perform functions such as printing
documents or authenticating users.
SMB is critical to ensuring that enterprise-level servers are secure and
interoperable with the networks they serve. Other applications of SMB include
peripherals such as printers and scanners, security cameras, televisions, and
some mobile devices.
Traditionally used in local area networks, SMB can also be used to transmit data
over virtual private networks and to cloud-based solutions. SMB is implemented
in Microsoft Windows as Microsoft SMB Protocol.
SMB FEATURES
EXTREMELY SECURE
Data transferred through SMB is protected from interception or alteration by
strong encryption.
RELIABLE FILE TRANSFER
Built-in redundancy ensures the accuracy and reliability of file transfers.
SUPERB INTEROPERABILITY
SMB enables seamless file transfer between Windows and non-Windows-based
operating systems, as well as a wide variety of device types.
COMMON IN MIXED ENVIRONMENTS
Because SMB is interoperable and secure, it is almost universal in environments
where multiple device types and operating systems interact.
HIGH EFFICIENCY
SMB does not require high bandwidth and generates low network noise.
SMB TECHNICAL DOCUMENTATION
While a technology license is required to implement SMB, Microsoft publishes
documentation about the SMB protocols:

REMOTE DESKTOP PROTOCOL (RDP)
We’re taking the Windows experience to new devices and places and empowering the
mobile worker.
View the protocol documents
Technology continues to transform the nature of work. Online and cloud
collaboration empowers workers outside the traditional office, making remote
work more connected, efficient, and productive. To realize the benefits of
remote work, connected workers require reliable, secure access to their data, as
well as a seamless user experience.
The Remote Desktop Protocol is the foundation of remote desktop client solutions
that take the Windows experience anywhere. RDP allows a user to open and use a
Windows desktop or application remotely, on a range of computers and mobile
devices, regardless of operating system or platform. Learn how to allow access
to your PC using RDP.
Windows environments do not need this additional technology license. Windows
desktop users have RDP built in. A server CAL is needed for server remote
desktop use. Get the Windows Server RDP CAL.
HOW RDP WORKS
RDP allows users of a remote client to connect securely to a server or virtual
machine over a network. RDP connects with, and channels communication between,
components of remote clients and servers. RDP is a multi-channel protocol, with
separate virtual channels carrying different types of data. These include
graphics data, keyboard and mouse user input, device communication, file system,
audio and video, and licensing information. The RDP protocol has applications in
secure business and government network solutions, including where an encrypted
desktop is required. RDP client software is also built into Windows Pro and
Enterprise. For developers building remote desktop client applications for
computers, phones, tablets, or other devices, Microsoft Technology Licensing
(MTL) offers a technology license for the RDP protocol set.
RDP FEATURES
INTEROPERABLE
RDP enables the Windows experience across a range of devices, and operating
systems.
SECURE
RDP enables a secure connection between a client and a server or virtual
machine. RDP can enable the delivery of an encrypted desktop.
ENABLES NETWORK TERMINALS
RDP enables the use of network terminals and “thin client” PCs, which provide
strong physical security by storing all data and documents remotely.
RDP TECHNICAL DOCUMENTATION
Although a technology license is required to integrate the RDP protocol into a
device, the RDP product documentation describing the RDP protocols is freely
available on the Microsoft Developers Network.
OUR RDP LICENSEES
Microsoft licenses RDP globally to several customers developing remote desktop,
cloud, and device solutions.
