Microsoft have releashed a Word document regarding the enhancements and changes they have done to their newly launched 64bit Windows XP Professional over over Windows XP Professional SP2.

The enhancements of 64bit Windows XP Professional include the following:-

• Data Execution Prevention (DEP) - 64bit enabled users should know this. It is basically an enhanced security that enforced by both hardware and software to protect against malicious code exploits.
• Files and Settings Transfer Wizard - Help previous Windows-based computer users to migrate their files to WinXP Pro x64.
• Internet Protocol security (IPsec) - Ensure private, secure communications over Internet Protocol (IP) networks.
• Outlook Express - Surprisingly in WinXP Pro x64, spell checking is not supported in Outlook Express.
• Remote Assistance - No Voice Session (VoIP), in other words, voice conversations is not supported. No escalation using e-mail in Remote Assistance too.
• Remote Desktop - Unicode keyboard input support, Client-side time-zone redirection, GDI+ rendering primitives support, FIPS encryption support, Fallback printer driver and Auto-reconnect.
• Search Companion - Well, again spell checking is not supported.
• Windows Installer - This will help you in installing applications.
• Windows Media Player - Windows Media Player 10 (WMP10) is installed. Microsoft claimed that WMP10 is the most secure version of Windows Media Player and it has been updated to work with the other security enhancements contained in WinXP Pro x64. Please be aware that this WMP10, handles licenses differently than previous WMP.

Those bolded are the enhancements that interest me.
Thinking of installing it to my dust-collecting harddisk.
