Aero: The look and feel of Windows Vista.

Aero Glass: The most sophisticated version of Aero, with 3D graphics, animation, transparency, and other visual effects. Available on systems with advanced graphics hardware

Avalon: Vista's graphics and media application programming interface (API), on which Aero is built. Will be available for application developers on Windows XP.

Indigo: A programming model for distributed applications based on .NET and using interconnected Web services. Will also be available to developers on Windows XP.

Monad: Code name for MSH (Microsoft Shell), a new command-line interface. No longer tied to Vista's release.

.NET: A term encompassing Microsoft's strategy for building complex applications and Web services, and the tools and platform for creating these.

NGSCB: Next-Generation Secure Computing Base. An ambitious new infrastructure, formerly known by the code name Palladium, that would, among other things, let compliant applications run in a special trusted mode while most operations ran in a more open environment. Little of the original vision is being implemented in the Vista time frame.

RSS: Though the acronym has a few meanings (the most common is Really Simple Syndication), all refer to a way of managing lists of information. Commonly used today for reading blogs and other Web content. Microsoft plans on using RSS and Simple List Extensions for managing all sorts of data.

Sidebar: Removed from Vista, the Sidebar was essentially an extension of the Windows system tray, residing at the side of the desktop and displaying customizable information.

Secure Startup Full Volume Encryption: On computer systems equipped with a Trusted Platform Module (see below) almost all of the boot drive will be encrypted. At start-up, the TPM will make the drive available. Hackers attempting to boot a different OS or use the drive in another computer will be denied access.

Trusted Platform Module: The TPM chip is basically a secure microcontroller on the motherboard, containing cryptographic capabilities and security algorithms. It delivers very secure data encryption and can control access to the computer even before the OS boots. The TPM provides support for Secure Startup Full Volume Encryption and for NGSCB by verifying the identity of the system accessing it. Many enterprise-destined desktops and notebooks include a TPM now; we expect it to become standard equipment.

Virtual folders: Not real folders, but folder icons tied to search queries. When clicked, they almost instantaneously retrieve documents based on standard file attributes, file type–specific metadata, or user-defined keywords.

WinFS: Windows Future Storage. A database-based file system that would have expanded the ways developers and users could work with files and other types of data. It won't make the initial release of Vista.

WinFX: Vista's programming model, incorporating Avalon, Indigo, and eventually WinFS. Successor to the Win32 API.

Ok That's all I have for you now!, more when available.
