• Windows Explorer is enhanced to make finding and identifying information easier

What Is the Index?

The desktop search functionality in Windows Vista is vastly improved over the searching features in Windows XP The Search function now includes an index of common

locations to speed up searching In addition, there are several different ways searches can

be performed

The index used for searching does not track all files on your computer Only the most commonly used file locations are indexed by default This keeps the size of the index down and increases the speed of searching

The locations indexed by default are:

• Offline files

• Start menu

• Users folder

You can add additional locations to be indexed if you store data outside of the default locations You can also select which file types are indexed within the defined locations For each indexed file type, you can select whether the contents of the file are indexed in addition to the metadata about the file that is collected For some file types, such as pictures, there is no value in attempting to index the content of the files

Demonstration 2: Configuring Indexing

In this demonstration, you will see how you can:

• Configure indexing locations

• Configure advanced indexing options

Key Points

The key points of this demonstration are:

• The Search feature in Windows Vista uses an index to speed up searching

• The index used by the Search feature indexes only specified locations and content

Ways to Search for Files

It can be time-consuming to find a single file in a large directory structure The Search feature in Windows Vista makes this faster and easier with multiple ways to search for files

Search Box

The Search box appears in the upper-right corner of Windows Explorer When you type

in the Search box, Windows Explorer dynamically performs a search of the current folder and all subfolders looking for files that match the term you have typed For example, if you type “inv” in the Search box, all files that begin with “inv” or have metadata

beginning with “inv” are displayed

Search Folder

The Search folder is useful when you don’t know the location of a file or you want to search multiple locations To find files in multiple locations, the Search folder performs searches on the index files location by default This location represents the index that can

be configured for searching and includes all the locations and file types configured to be indexed

Complex search queries can be created in the Search folder by searching for particular properties and combining multiple search clauses together using the logical operators AND and OR For example, you could search for all files authored by yourself AND modified in the last 7 days

Start Menu

There is a Search box located at the very bottom of the Start menu When you enter a term in this Search box, Windows Vista automatically searches for programs and Microsoft Internet Explorer® favorites in the index

Demonstration 3: Performing Searches

In this demonstration, you will see how you can:

• Use the Search box

• Use the Search folder

• Search from the Start menu

Key Points

The key points of this demonstration are:

• There are multiple ways to search for files and folders

What Is Metadata?

Metadata is information about a file rather than the contents of a file For example,

metadata about a document can include the author, creation data, and last edited date Sometimes metadata is referred to as the properties of a file

Windows Vista includes metadata in searches If files are indexed, metadata is included

as part of the indexing process

The metadata collected varies for particular file types For example, pictures taken with a digital camera include information about lighting conditions, shutter speed, and other information that is not relevant to a Microsoft Office Word document

To customize the metadata that is collected for a file, Windows Vista stores tags for all file types Tags are keywords you can add to a file that are searchable For example, you can label all of the documents related to a particular project with the name of that project Home users can add tags to their digital photos describing which vacation they were taken on After tags are added to a file, you can search for files based on those tags

What Are Saved Searches?

Windows Vista includes a new feature called saved searches to make finding your data easier A saved search appears as a folder in Windows Explorer The contents of the folder are the results of a search Earlier versions of Windows Vista referred to saved searches as virtual folders

You can create your own custom saved searches, but some commonly used searches exist

by default The default saved searches cannot be changed

The default saved searches are:

• Attachments

• Favorite Music

• Fresh Tracks

• Important E-mail

• Indexed Files

• Last 7 Days E-mail

• Last 30 Days Documents

• Last 30 Days Pictures and Videos

• Recently Changed

• Shared By Me

• Unread E-mail

Demonstration 4: Creating a Saved Search

In this demonstration, you will see how you can:

• Add tags to files

• Create a saved search

Key Points

The key points of this demonstration are:

• Tags can be added to any file and used in searching

• You can create saved searches that behave like folders

Productivity Utilities

Introduction

Windows Vista includes new utilities to enhance user productivity Windows Vista

supports Peer Name Resolution Protocol and People Near Me as infrastructure services to find peers for peer-to-peer networking Windows Meeting space takes advantage of People Near Me to invite participants to collaborative virtual meetings Speech

Recognition is also included and can increase productivity for poor typists and people with motor impairment

Objectives

After completing this section, you will be able to:

• Describe Windows Vista collaborative technologies

• Describe Windows Meeting Space

• Understand how Windows Meeting Space can be used

• Describe Speech Recognition

• Understand how to improve Speech Recognition accuracy

What Are the Windows Vista Collaboration Technologies?

Peer-to-peer networking is a powerful tool for business and consumers The main

benefits of peer-to-peer networking for collaborative applications are massive scalability and reliability

In a peer-to-peer network, all communication is performed directly between two client computers Because a central server is not required, there is no central component to become overwhelmed by a high volume of requests Also, without a central server, there

is no single point of failure in the system

The main difficultly with peer-to-peer networking is the discovery of other computers to communicate with Windows Vista includes People Near Me (PNM) and Peer Name Resolution Protocol (PNRP) for collaborative applications to use to find other computers

People Near Me

People Near Me is a new feature in Windows Vista that allows collaborative applications

to find other computers to collaborate with The scope of People Near Me is intentionally limited to a single subnet From a development perspective, People Near Me simplifies the creation of peer-to-peer applications by providing the underlying infrastructure

required to find and connect with peers

From the perspective of a user, People Near Me is an icon in the Networking category of Control Panel In this icon, users can select a display name, sign in to People Near Me, and control other People Near Me characteristics After the user is signed in, the user can use the application to find other users to collaborate with The primary collaboration application shipped with Windows Vista is Windows Meeting Space, the successor to Microsoft NetMeeting® A user can also send an invitation without first opening the application, by referencing it with a GUID

Peer Name Resolution Protocol

The Peer Name Resolution Protocol is not configured by users in any way It is a protocol that can be used by collaborative applications to communicate in a massively scalable peer-to-peer network over large corporate networks or the Internet Like People Near Me, PNRP simplifies the development of peer-to-peer applications by providing the

underlying infrastructure required to find and connect with peers, but on a much larger scale

To achieve the scalability required by PNRP, Internet Protocol version 6 (IPv6) is used The larger address space of IPv6 allows each application on each computer in the peer-to-peer network to be uniquely identified with its own IPv6 address However, IPv6 is not supported on most corporate networks or the Internet To allow communication over IPv4 networks, PNRP requires the use of a tunneling technology named Toredo Toredo allows IPv6 packets to be tunneled inside IPv4 packets to traverse IPv4 networks

Demonstration 5: Configuring People Near Me

In this demonstration, you will see how you can:

• Configure People Near Me

Key Points

The key points of this demonstration are:

• People Near Me allows peer-to-peer applications to find other users on the local subnet

What Is Windows Meeting Space?

Windows Meeting Space (formerly Windows Collaboration) is a peer-to-peer

collaboration application that allows up to 10 people with Windows Vista systems to remotely work together as if they were in the same room To locate other participants on the local network, Windows Meeting Space uses People Near Me However, to start a session over the Internet, you must use an e-mail invitation or a file invitation

By using Windows Meeting Space, you can:

• Share your desktop or any program with other session participants

• Distribute and co-edit documents on each others computers

• Pass notes to other participants

• Connect to a network projector to give a presentation

Windows Meeting Space Scenarios

Windows Meeting Space is designed to make collaboration easier It can be used in a variety of business situations to reduce costs and enhance communication All

communication between the participants is encrypted

Single-Site Collaboration

In many organizations, it is difficult to obtain meeting rooms and data projectors for meetings Workgroups of up to 10 people in an organization can have a virtual meeting using Windows Meeting Space This eliminates the need for a meeting room or a data projector Windows Meeting Space can be used to display and edit project documents At the same time, participants can be on the phone talking about the documents If all

participants are on the same subnet, People Near Me can be used to perform all of the invitations

Multiple-Site Collaboration

In multiple-site organizations, travel between locations for meetings is a drain on time and productivity Windows Meeting Space allows you to eliminate travel for some

meetings For meetings that would have already been phone-based, Windows Meeting Space can enhance the meeting by allowing real-time collaboration on documents rather than just a review of an existing document External sites can include the Internet To perform collaboration outside of the local subnet, e-mail invitations or file invitations must be used

Improvised Collaboration

With a portable computer that is capable of wireless networking, you can perform

improvised collaboration anywhere For example, you could meet a colleague at a coffee shop and collaborate on the creation of a document

Demonstration 6: Using Windows Meeting Space

In this demonstration, you will see how you can:

• Use Windows Meeting Space

Key Points

The key points of this demonstration are:

• Windows Meeting Space can be used to collaborate

• People Near Me can be used to find other participants for Windows Meeting Space

What Is Speech Recognition?

Speech Recognition is a system built into Windows Vista so that you can use your voice

to control your computer You can control Windows Vista, control applications, and dictate text This can be useful for anyone with impaired motor skills, or someone who is just a poor typist

To control Windows Vista and applications, you must use specific commands that are keywords for Speech Recognition Some of the commands are:

• Click

• Double-click

• Scroll [up|down|left|right]

• Start listening

• Stop listening

• Open application

When you dictate text, you simply speak into the microphone, and Speech Recognition converts what you say into text on the screen This is similar to having a secretary take dictation There are a number of commands specifically for correcting recently dictated text that is not recognized properly

How to Improve Speech Recognition Accuracy

Speech Recognition is able to recognize a lot of words using the default configuration that is available upon installation However, even a small number of mistakes in word recognition, add significant editing time

To be as productive as possible, you should do the following to improve Speech

Recognition accuracy:

• Train your computer to better understand you Each person has slightly different

pronunciation of words To account for these differences, you can train Speech

Recognition by reading predefined selections of text Reading the predefined

selections of text to Speech Recognition allows Speech Recognition to adjust to your production of particular sounds

• Use the Speech Dictionary The Speech Dictionary allows you to correct Speech

Recognition when it does not recognize a word properly, and when you use a word it does not understand

• Use your own speech profile When you train the computer to understand you and

make modifications to the Speech Dictionary, the changes are stored in a speech profile To be effective, the profile must be for a specific user If multiple users attempt to share a speech profile, the changes made by one user will decrease the accuracy for the other users
