Power Plan Description
Power SaverThis plan saves power on a mobile computer by reducing system performance. Its primary purpose is to maximize battery life.
High performance
This plan provides the highest level of performance on a mobile computer by adapting processor speed to your work or activity and by maximizing system performance.
BalancedThis plan balances energy consumption and system performance by adapting the computer’s processor speed to your activity.
Method for turning a computer on or off
Data Storage State Power Needs
Sleep or Standby System State Saved to Memory Low

What Are Remote Desktop and Remote Assistance?
Remote DesktopRemote Desktop Remote AssistanceRemote Assistance
• A Windows 7 feature that enables users to connect to their desktop computer from another device
• Enables administrators to connect to multiple remote servers for administrative purposes
• A Windows 7 feature that enables users to connect to their desktop computer from another device
• Enables administrators to connect to multiple remote servers for administrative purposes
• A Windows 7 feature that enables support staff to connect to a remote desktop computer
• Optionally allows for remote control of that computer
• Assistance can be sought or offered

Configuring Remote Desktop includes setting it up on the remote computer
and the host computer.
Host Computer
• Launch the Remote Desktop Connection
• Choose Options to see the Remote Desktop configuration settings
• On the General Tab, enter the remote computer’s name and your authentication credentials
• Save your Connection Settings• Select preferences on the remaining
Option’s tabs

VPNs are point-to-point connections across a private or public network. A VPN client uses special protocols, called tunneling
protocols, to make a virtual call to a virtual port on a VPN server

What Is a VPN Connection?
PPTP uses Point-to-Point Protocol (PPP) for user-level authentication and Microsoft Point-to-Point Encryption
(MPPE) for encryption

L2TP uses PPP authentication and IPsec encryptionL2TP uses PPP authentication and IPsec encryption
VPN connections use either Point-to-Point Tunneling Protocol (PPTP), Layer Two Tunneling Protocol/Internet
Protocol security (L2TP/IPsec), or Secure Socket Tunneling Protocol (SSTP)
VPN connections use either Point-to-Point Tunneling Protocol (PPTP), Layer Two Tunneling Protocol/Internet
Protocol security (L2TP/IPsec), or Secure Socket Tunneling Protocol (SSTP)
SSTP uses PPP framing on top of Secure Sockets Layer (SSL)
Creating a VPN Connection
Creating a VPN connection in the Windows 7 system environment requires authenticated access to a Windows
a VPN Server
From the Network and Sharing Center- choose to the Setup a new connection wizard or type VPN at the Windows 7 search bar
Choose Connect to a workplace – Set up a dial-up or VPN connection Create a new connection
Select your VPN server after choosing Use my Internet Connection (VPN)
What Is DirectAccess?
FeaturesFeatures
• Provides users transparent access to internal network resources whenever they are connected to the Internet
• Enables IT Professionals to manage remote computers outside of the office
• Establishes a bi-directional connection that enables the client computer to remain current with company policies and to receive software updates
• Does not require a VPN connection
• Supports multifactor authentication methods
• Configurable to restrict which servers, users, and individual applications are accessible
• Provides users transparent access to internal network resources whenever they are connected to the Internet
• Enables IT Professionals to manage remote computers outside of the office
• Establishes a bi-directional connection that enables the client computer to remain current with company policies and to receive software updates
• Does not require a VPN connection
• Supports multifactor authentication methods
• Configurable to restrict which servers, users, and individual applications are accessible
How DirectAccess Works
Selected Server Full Enterprise Network Selected Server Full Enterprise Network
Configured using DirectAccess console or IPsec policiesConfigured using DirectAccess console or IPsec policies
• IPsec session is established between the DirectAccess client and server
• IPsec is not used for communications across the internal network
• Enterprise internal security is unchanged
• Closely resembles VPN and can be more straightforward to deploy
• IPsec session is established between the DirectAccess client and server
• IPsec is not used for communications across the internal network
• Enterprise internal security is unchanged
• Closely resembles VPN and can be more straightforward to deploy
• Deploy IPv6 and IPsec in the organization
• Upgrade application servers Windows Server 2008 R2
• Enable selected server access• Allows end-to-end authentication and
encryption from the DirectAccess client to internal resources
• Deploy IPv6 and IPsec in the organization
• Upgrade application servers Windows Server 2008 R2
• Enable selected server access• Allows end-to-end authentication and
encryption from the DirectAccess client to internal resources

What Is BranchCache?
Key benefits for IT professionalsKey benefits for IT professionals
Remains transparent to the userRemains transparent to the user
Optimizes traffic flow between clients and serversOptimizes traffic flow between clients and servers
Supports commonly used network protocolsSupports commonly used network protocols
Supports end-to-end encryption between clients and serversSupports end-to-end encryption between clients and servers
Provides compatibility with end-to-end security protocolsProvides compatibility with end-to-end security protocols
Helps reduce WAN link utilizationHelps reduce WAN link utilization
Distributed Cache Mode
Cache is distributed across client computers
Additional client computers retrieve content from the first requesting client computer
Beneficial for branch offices that do not have a local server with Windows Server 2008 R2
Hosted Cache Mode
Cache is on a server at the branch office
Client computers retrieve content from the branch office server
Beneficial for larger branch offices that have hardware resources for a local server with Windows Server 2008 R2
Client computers are configured to use only one caching mode at a time.
