Windows "Longhorn" FAQ

Once envisioned as a minor upgrade to Windows XP, Windows "Longhorn" took on all-new importance in early 2002 when Microsoft decided to reach for the brass ring and make the new Windows release an all-encompassing major upgrade with a new security architecture called Palladium, a 3D-enabled user interface, and brand-new, database-based file system, and many more exciting new features. Here's the first--and most comprehensive--Longhorn FAQ ever created, constantly updated to include the latest information about this release.

Q: What is "Longhorn"?
A: Longhorn is the next major Windows release, which will follow Windows XP and XP Service Pack 1 (SP1). Originally expected to be a fairly minor upgrade, Longhorn will now include a number of new features including a revised task-based (or "inductive") user interface, an extensible, dock-like, Start panel, and a SQL Server 2003-based file system.

Q: So what will be new and different in Longhorn?
A: Though speculation on Longhorn continues, what we know about this Windows release is steeped in generalities and rumors. Given that, here's what we know about Longhorn:

• Longhorn will feature a task-based (or "iterative") interface that goes far beyond the task-based interface found today in Windows XP. Microsoft has been working to move beyond the dated desktop metaphor still used by Mac OS X and Linux for many years.
  
• The Longhorn Start Menu will likely take on the form of the Task Panes from Office XP and occupy a good percentage of the right- or left-most portion of the Longhorn desktop.
  
• Longhorn will take full advantage of 3D video hardware to render special effects that will make the screen more photorealistic and deep. This doesn't mean that the basic windows and mouse interface is being replaced, just that it will look a lot better.
  
• Longhorn will optionally include the Palladium technology Microsoft is developing with Intel and AMD (see the next question for details).
  
• Longhorn will include a database-like file system based on technology from SQL Server 2003 (code-named Yukon). This file system will abstract physical file locations from the user and allow for the sorts of complex data searching that are impossible today. For example, today, your email messages, contacts, Word documents, and music files are all completely separate. That won't be the case in Longhorn.
  
• Longhorn will include integrated DVD+R and DVD+RW DVD burning capabilities. Digital media enthusiasts will be able to copy video from a digital camcorder directly to DVD+R, bypassing the system's hard drive entirely, if desired.

Q: What's with this Palladium stuff I keep hearing about?
A: One of the most exciting aspects of Longhorn is its integration with Palladium, Microsoft's technology for realizing the Trustworthy Computing vision. Palladium is basically a secure run-time environment for Windows and other operating systems that allows a coming generation of software applications and services to protect the end user from privacy invasion, outside hacking, spam, and other electronic attacks. Palladium requires special hardware security chips and microprocessors (which will be made by Intel and AMD) and doesn't interfere with the normal operation of the PC. That is, Palladium-based PCs will still operate normally, working with legacy operating systems and applications. But specially-made Palladium applications and services will offer a range of features of functionality not found in the non-Palladium world, and if the initiative is successful, we'll one day be running only Palladium-based software.

If you're familiar with the .NET model, you might be aware of the notion of "managed" and "non-managed" (or legacy) code. Palladium will institute a similar model for PC software, where a trusted execution mode is used for Palladium applications and services and the old, "untrusted" mode is used for legacy code.

Microsoft designed Palladium around the following ideals:

• Palladium will tell you who you're dealing with online, and what they're doing. It will uniquely identify you to your PC and can limit what arrives (and runs on) that computer. Information that comes in from the Internet will be verified before you can access it.
  
• Palladium protects information using encryption to seal data so that "snoops and thieves are thwarted." The system can maintain document integrity so that documents can't be altered without your knowledge.
  
• Palladium stops viruses and worms. The system won't run unauthorized programs, preventing viruses from trashing your system.
  
• Palladium stops spam. Spam will be stopped before it even hits your email inbox. Unsolicited mail that you might actually want to receive will be allowed through if it has credentials that meet your user-defined standards.
  
• Palladium safeguards privacy. In addition to the system's ability to seal data on your PC, Palladium can also seal data sent across the Internet using software agents that ensure the data reaches only the proper people. Newsweek reports that the agent has been nicknamed "My Man," a goof on ".NET My Services," "My Documents," and other similar names at Microsoft.
  
• Palladium controls information after it's sent from your PC. Using Digital Rights Management (DRM) technology, Palladium can be used to securely distribute music, movies, and other intellectual property securely over the Internet. Movie studios and the recording industry could use this technology to let their customers exercise their fair use rights to copy audio CDs and movies, for example. "It's a funny thing," says Bill Gates. "We came at this thinking about music, but then we realized that e-mail and documents were far more interesting domains." Gates says that Palladium could ensure that email designated as private could not be forwarded or copied to other people, for example. Or, the Newsweek reports reads, "you could create Word documents that could be read only in the next week. In all cases, it would be the user, not Microsoft, who sets these policies."

Q: I thought the next version of Windows was code-named "Blackcomb."
A: The existence of Longhorn was first revealed by Windows product manager Tom Laemmel, who I met July 17, 2001 during an XP press tour. Laemmel spilled the beans to eWeek a few days later, and Microsoft executive vice president Jim Allchin verified that a new interim release, Longhorn, would ship before Blackcomb. Since then, information about Longhorn has appeared in Microsoft and Department of Justice (DOJ) legal filings related to the Microsoft antitrust case. It's real, and now it's common knowledge.

Q: So when will Longhorn ship?
A: Microsoft originally said that we could expect Longhorn in late 2002 or early 2003, but the release was recently pushed back until late 2004. This suggests that an XP refresh, possibly called Windows XP Second Edition (XP2E) will ship first, in late 2003.

Q: When will the Longhorn beta start?
A: After Windows XP shipped, Microsoft said that the beta for the next version wouldn't start until the beta for Windows XP SP1 was completed. That will happen in mid-August, so I expect the Longhorn beta to begin sometime this fall.

Q: What's up with the name Longhorn?
A: The name wasn't chosen randomly. Remember that Windows XP was code-named Whistler and the next major version of Windows is code-named Blackcomb. Both of these names come from ski areas in British Columbia, close to Microsoft's headquarters. At the foot of Whistler Mountain, there is a saloon named Longhorn that serves the local skiing population. So if you're ever in the area and want to take in some local color, Longhorn is a nice stop… after you're done with Whistler.
