4. …the PC of today can do more
Advanced CPUs -- Multiple Cores, 64-bit
Lots of memory – many threads, tasks
Lots of storage – easily expandable
Power friendly – on demand on/off/sleep
Rich Connectivity – any bus, any radio
Dependable Protocols – secure, powerful
Dependable Platforms – easy, stable
How do we harness the advances in devices and PCs for a healthy ecosystem?

5. The Need A new class of device is emerging - a new inflection point
Multi-function
Mobile
For Windows PC users
The experience should be the same whether a device is IP connected, USB connected, BT connected, ….
For the industry
New business opportunities
Build new types of devices that work great with Windows
Without
Significantly adding to development, deployment & support

6. The Challenges Devices that “come” and “go”
Must associate securely, yet simply with the PC
User experience must be simple: easy to understand and use
Devices that are multi-faceted
Is it a cell phone? Or an MP3 player? A camera? A storage device?

7. Microsoft’s Investments for the Windows Device Ecosystem

8. Vision for the Windows PC and devices
Devices just work – independent of how they connect to Windows
Drivers don’t exist
Administrators and users don’t know that drivers exist, the OS ‘figures out’ how to work with the HW
The system transparently manages locating and installing the appropriate driver for the device
System Integrity
Adding or removing a device does not compromise the stability, usability, security, or integrity of the system and the components (devices, applications) installed on it
Innovation
Provide a platform for device innovation and partner added value while ensuring a consistent user experience
Compatibility
Preserve our customers’ and partners’ investments

9. Déjà Vu … all over again Remember? Solved with PnP
Windows 3.1 supported devices only if the user could configure them
No common device install experience
Vendor utilities detected and configured their devices
Support in Windows for only a limited set of device classes
Conflicts and hangs were the rule, not the exception
Users were frustrated, vendors were frustrated
Fear of configuration and installation issues stymied hardware sales
It was quite a mess…
Solved with PnP
Provided infrastructure

13. Windows Connect Now A Building Block available for XP SP 2
Problem
Setting up a home / small office wireless network is a pain
Multiple devices
Multiple vendors
Complex to setup security; usually defaults to unsecured
Solution
Build on familiarity of USB flash drives
Build into the Windows Platform
Use the PC (Wizard) to define settings and store on flash drive
Use flash drive to transfer settings to devices
Value Proposition
Simplifies the deployment of secure wireless networks
Adding network-connected devices requires no UI, e.g.
Internet Gateway Devices / Wireless Access Points
Printers / All-In-One Devices
Photo Stations
Pocket PC
Projectors
Security is automatic
Architecture supports complete home or small business network provisioning
LAN, WAN, WLAN, Broadband modems

14. Consistent Device Install A Building Block for the future you can build on today
Problem
End users can be become frustrated with install experience
IT managers find deployment challenging and time consuming
Multiple devices integrated in one package (e.g., Multi-function Printers) represent additional complexity
Support call generator
Solution
Consistent Device Install
Treat compound devices as a “single piece of plastic”
Solve it once – including loosely-connected devices
Value Proposition
Device installation is error free and extensible for vendor branding
Uninstalling a device is error free and leaves the system stable
End user is confident to install / uninstall devices
When things go wrong, Windows is able to diagnose
IT managers can limit installation of certain devices for security
IT managers can easily deploy packages across multiple systems
Availability
Tools available for XP SP2 and migrate to future releases

15. Plug and Play Extensions A Building Block for the future you should plan for today
Problem
Integration of loosely-connected devices in PC scenarios is currently difficult for users
Limitations exist
Security, complex data types, enterprise friendly wire protocols
Solution
Extend the driver model and enable UPnP/PnP integration
Discovery, description and association in Windows
Value Proposition
Makes a loosely-connected device look like a tightly-coupled device: simplifies installation, configuration and use
Allows developers to take advantage of the PnP co-installer
Availability
Future Windows Releases

16. Digital Media Opportunities
Focus on Digital Media Receivers

17. Near Term Opportunity Market Overview for Digital Media Receivers
Households with home networks to reach 15 million in 2004, and top 31 million in 2008.
17% of consumers said they would like to share an Internet connection among several PCs.
24 % of consumers would like to listen to music stored on a PC via their home stereo system.
As home networks proliferate … more consumers will look to move or share music from a PC to other PCs or CE devices in their homes.
