Microsoft Internet Explorer 5.5 for Windows CE This feature now includes support for IPv6 and Kerberos security.
NTLM v2 authentication protocol This feature is implemented as a security package that is accessible through the Security Support Provider Interface (SSPI). NTLM v2 has several enhancements that address security issues and session security requirements for confidentiality, integrity, and 128-bit encryption.
Power Manager This feature now includes the following enhancements:
  • An enhanced Power Control Panel utility.
  • Improved support for the suspend and resume states. PC Card client drivers can stay loaded during suspend and be used as a wake-up source. A network connection can be maintained during suspend.
Speech API (SAPI) This feature is a subset of the Microsoft Speech Application Programming Interface (SAPI) version 5.0. SAPI 5.0 is a programming standard for speech recognition and converting text to speech. Speech recognition applications allow a computer to respond to spoken commands. Text-to-speech applications allow a computer to synthesize a voice that speaks words that are in a string or text file.
TCP/IPv6 support This feature is a suite of standard protocols that is the next generation of network layer protocols for the Internet. Using 128-bit addresses, IPv6 provides more IP addresses than its predecessor, IPv4, which uses 32-bit addresses. Internet Explorer, Windows Media Player, and Windows Media Technologies all support IPv6.
Windows Messenger for Windows CE .NET This feature is a client application that combines real-time voice and text communications with file transfer capability. Windows Messenger is presence-enabled. This means that the users can see who is available online before they try to contact other people and can control their online status, which other people see. The user can also initiate remote assistance, multiplayer games, and other applications using Windows Messenger.

The Windows Messenger client leverages the Communications Service provider, the Session Initiation Protocol (SIP) stack, the Real-Time Protocol (RTP) stack, and the MSN Messenger protocol stack.
