__ Whistler 5.10.2202 Alpha 02/02/2000 2202 Rare - an internal leak of Whistler build 2202. This version just appeared recently
__ Whistler 5.10.2211 Alpha 03/20/2000 2211 Rare - Originally the first leaked Whistler build. Basically Neptune, with some minor bug fixes.
__ Whistler 5.10.2211.1 Beta ??/??/19?? 2211.1
__ Whistler 5.10.2214 Beta ??/??/19?? 2214
__ Whistler 5.10.2222 Alpha 04/07/2000 2222 Only Screenshots Leaked
__ Whistler 5.10.2223 Beta ??/??/19?? 2223
__ Whistler 5.10.2223.1 Alpha 04/17/2000 2223.1 Still no major changes from Windows 2000. There were some minor GUI updates in this build.
__ Whistler 5.10.2239 Preview Release ??/??/2000 2239 Advanced Server - The first Whistler Advanced Server build. It had an updated Configure your Server wizard, as well as some GUI changes
__ Whistler 5.10.2240 Beta ??/??/19?? 2240
__ Whistler 5.10.2250 Preview Release 07/13/2000 2250 The first major change from Windows 2000. This was the first build that included support for Visual Styles. It shipped with an obviously unfinished and buggy one, but it worked. Any build before this was an internal leak.
__ Whistler 5.10.2257 Preview Release 08/24/2000 2257 This build improved upon the theme in 2250 with the beginnings of the well-known Watercolor theme. It had the first new-style start menu (2250 had it, but it was hidden). -Internal leak
__ Whistler 5.10.2267 Pre-Beta 1 10/03/2000 2267 Advanced Server - Another Advanced Server build. This included the Watercolor theme, as well as more enhancements to the Configure your Server wizard, among others.
__ Whistler 5.10.2276 Pre-Beta 1 09/28/2000 2276 This build contained a new background wallpaper, and more enhancements to the Watercolor theme, but it was much buggier than previous builds. This was another official build.
__ Whistler 5.10.2287 Pre-Beta 1 10/12/2000 2287 This was basically a massive bug fix for 2276. It was much more stable than 2276, and contained slight changes to the UI as well. Another official build.
__ Whistler 5.10.2295 Beta ??/??/19?? 2295
__ Whistler 5.10.2296 Beta 1 10/31/2000 2296 This was the first major milestone build for Whistler. It provided many UI enhancements, especially in the Explorer folder views.
__ Whistler 5.10.2297 Beta ??/??/19?? 2297
__ Whistler 5.10.2410 Beta 1 01/04/2001 2410 This build saw a massive update to the Watercolor theme. Being over 100 builds from Beta 1, it contained many changes. The icons were completely different, the start menu was enhanced, the Explorer folder view was further changed, and there were many, many bug fixes.
__ Whistler 5.10.2411 Beta ??/??/19?? 2411
__ Whistler 5.10.2416 Beta 1 01/16/2001 2416 This build featured another new icon set, as well as a larger start menu than 2410.
__ Whistler 5.10.2419 Beta 1 01/23/2001 2419 This was not that much of a change from 2416, except for 2 things: 1, the start menu was bloated even further than it already was, and 2, this was the first build containing Windows Product Activation. This was the last build to contain the Watercolor theme.
__ Whistler 5.10.2426 Beta ??/??/19?? 2426
__ Whistler
(Windows XP) 5.10.2428 Beta 1 02/13/2001 2428 Luna. Need I say more? I hope not, because that's about it; Luna replaced Watercolor as the theme, and the logon screen was changed.
__ Whistler
(Windows XP) 5.10.2432 Beta 1 ??/??/2001 2432 Public Demonstration. Build not leaked.
__ Whistler
(Windows XP) 5.10.2235 Beta ??/??/19?? 2235
__ Whistler
(Windows XP) 5.10.2439 Beta 1 ??/??/2001 2439 Speed enhancements, slight UI improvements. -Internal leak
__ Whistler
(Windows XP) 5.10.2442 Beta ??/??/19?? 2442
__ Whistler
(Windows XP) 5.10.2446 Beta 1 03/05/2001 2446 This build featured many enhancements to the Luna UI, including a divider arrow between the taskbar and systray and some new wallpapers.
__ Whistler
(Windows XP) 5.10.2454 Beta 1 03/06/2001 2454 Not much different from 2446; a couple bug fixes, driver updates, etc. -Internal leak
__ Whistler
(Windows XP) 5.10.2458 Beta 1 03/10/2001 2458 Noticeably faster than 2454, and not as buggy.
__ Whistler
(Windows XP) 5.10.2462 Beta 2 03/15/2001 2462
__ Whistler
(Windows XP) 5.10.2463 Beta 2 03/28/2001 2463 One bug with remote desktop corrected. -Internal leak
__ Whistler
(Windows XP) 5.10.2464 Beta ??/??/19?? 2464
__ Windows XP 5.10.2465 Beta 2 04/26/2001 2465 The first interim after Beta 2, and probably the buggiest as well. This contained a new background wallpaper set, and the UI said Windows XP in many places instead of Whistler for the first time. However, it caused problems with certain programs, including Office XP, and was generally unstable.
__ Windows XP 5.10.2468 Beta ??/??/19?? 2468
__ Windows XP 5.10.2469 Beta 2 05/12/2001 2469 This was the first build that was very hard to crack. Well, no, not hard: impossible. There was never a true crack for this build. The Reset workaround was developed for this build. Direct3D didn't work in 2469 either, so this was a very unpopular build.
__ Windows XP 5.10.2470 Beta ??/??/19?? 2470
__ Windows XP 5.10.2474 Beta 2 05/08/2001 2474 The first build which contained Windows Messenger, which is basically MSN Messenger combined with NetMeeting. The build was buggy and somewhat slow, but that's to be expected of internal leaks, which this was.
__ Windows XP 5.10.2475 Beta 2 05/14/2001 2475 This build was almost identical to 2474, but less buggy, and it did not have Windows Messenger in it.
__ Windows XP 5.10.2479 Beta ??/??/19?? 2479
__ Windows XP 5.10.2481 Beta 2 05/23/2001 2481 Finally, a major update to the UI. This build had 2 new themes, Metallic and Homestead. It also boasted a major improvement in speed and stability over 2475. This build was leaked to IRC before MS released it to technical beta testers.
__ Windows XP 5.10.2485 Beta 2 05/31/2001 2485 This build was faster than 2481, but not quite as stable. -Internal leak
__ Windows XP 5.10.2486 Beta 2 06/06/2001 2486 Speed of 2485, stability of 2481, and renamed themes to Silver and Olive.

__ Windows XP 5.10.2494 Beta 2 06/13/2001 2494 Not much different from 2486. Microsoft was just polishing up for RC1 in this build.
__ Windows XP 5.10.2495 Beta 2 06/14/2001 2495 This build actually leaked before 2494 was released, so there must have been something wrong with it, but nobody really found out what. If you know, let us know -Internal leak
__ Windows XP 5.10.2497 Beta 2 06/??/2001 2497
__ Windows XP 5.10.2498 Beta 2 06/??/2001 2498 Nobody really cared about this build, because it leaked at the same time as 2499, so I don't have any info on it. If you do, let me know. -Internal leak
__ Windows XP 5.10.2499 Beta 2 06/19/2001 2499 Nobody really cared about this build either, to tell the truth. It had some improvements over 94/95 in speed, and some bug fixes, but thats really about it. -Internal leak
__ Windows XP 5.10.2500 Beta ??/??/19?? 2500
__ Windows XP 5.10.2502 Beta 2 06/22/2001 2502 Speed, bug fixes, blah blah; you wont hear that much after this, really
__ Windows XP 5.10.2504 Beta 2 06/25/2001 2504 Once again, speed improvements, bug fixes -Internal leak
__ Windows XP 5.10.2505 RC 1 06/26/2001 2505 The first feature-complete version of XP. This was the first build available to the public, except for beta 2 if you were one of the first 20,000 people to sign up for the Windows Preview Program.
__ Windows XP 5.10.2508 Beta ??/??/19?? 2508
__ Windows XP 5.10.2509 RC 1 07/01/2001 2509 Very buggy build. Some DirectX things didn't work properly or at all. IE version contained commas instead of periods, which isn't that big of a deal, but it's still kinda funny -Internal leak
__ Windows XP 5.10.2517 RC 1 07/13/2001? 2517 Fixed many of the bugs in 2509, and was faster, too. -Internal leak
__ Windows XP 5.10.2520 RC 2 07/24/2001 2520 The only interim between RC1 and RC2. Stable and fast.
__ Windows XP 5.10.2525 RC 2 07/23/2001 2525 Bug fixes from 2520. -Internal leak
__ Windows XP 5.10.2526 RC 2 07/24/2001 2526 Faster than 2520 and less buggy, and performs better in Quake 3 than any other build according to A-KO^.
__ Windows XP 5.10.2529 Beta ??/??/19?? 2529
__ Windows XP 5.10.2531 RC 2 07/30/2001 2531 Not too different from RC2. Slightly faster. -Internal leak
__ Windows XP 5.10.2532 RC 2 07/31/2001 2532 Almost identical to 2531. Only a couple bug fixes, most likely. -Internal leak
__ Windows XP 5.10.2535 RC 2 08/03/2001 2535 Bug fixes, and the wallpaper reverted to the old grassy one as opposed to the newer Windows logo backgrounds.
__ Windows XP 5.10.2536 Beta ??/??/19?? 2536
__ Windows XP 5.10.2542 RC 2 08/11/2001 2542 Bug fixes, and finalized WPA. Previous keys do not work on this build. Beta tester keys work for 30 days instead of 14 with no activation. Pro and home have seperate keys now.

WOW! I'll never get that many betas...

Post by **tpemail** » Sun Dec 03, 2006 1:23 am

That list was year old and OBrasilo and I were modifing it.
We planned to do major fix and release that after Vista Retail released.

Post by **empireum** » Sun Dec 03, 2006 2:16 am

Wow, there are many builds I didn't even know of...
One question though: What's up with these (beta) builds that have build numbers higher than the retail version? Some examples:

- NT 4.0 builds higher than 1381
- NT 4.5 (what's that? Never heard of it)
- Windows 2000 builds higher than 2195
- Windows XP builds higher than 2600
- Windows 2003 build 3800

These are all builds numbers higher than these of the final version. What were these versions meant for? I suppose they must be very rare. Has anybody seen them?

I doubt about their existence too. No one ever heard of NT4 1401 as retail.
But at the current modification OBrasilo and I hadn't remove them yet. As we can't prove that they don't exist either.

Post by **empireum** » Sun Dec 03, 2006 2:42 am

OK, thanks!
Do you happen to know anything about NT 4.5? I've been stumbling over the term "NT 4.x" for some time now, and that suggests there's more than NT 4.0... Could this be the version of NT shipping with SBS 4.5?

Nope. We know nothing about NT4.5 either. Also Windows 3.15 is doubtful.
It was nearly only mentioned on Japanese sites, which seems to be a Japanese only product. But the screenshot on wikipedia is in English. That's really unexplainable for a Japanese project, as they would translate every English lines to Japanese (even the texts in BSODs and error messages while loading Win9x.)
I could find a Japanese BSOD screen of Win95 if anyone interested in it.

btw...the newest checklist we just finished modifying:

Post by **___** » Mon Jan 29, 2007 8:20 pm

well vista is build 6000, so that makes probably at least a few thousand

Post by **Le Master** » Sat Mar 10, 2007 8:20 am

That list shows that Whistler Build 2309 was a fake but I had it installed at one point. I remember it having a few features that they took out by the next build, like some new folders in My Documents and there was something different about the Remote Desktop.

Does anyone have this build? I remember loving how stable it was on my machine. It seems to be missing out of my large stack of Whistler CD's. (This is not a request, I'm just curious).

Post by **empireum** » Sat Mar 10, 2007 8:27 am

Judging from the screenshots existing of "2309", I'd say this was certainly a fake. The compile date, for instance, is hilarious. AFAIK, there were no known 23xx builds at all.

I doubt it. The (AMD) 64-bit builds have numbers starting with 3xxx, the 2002 IA64 build should be 2600 as is the x86 one. Final of 2003 IA64/AMD64 is 3790 as it's the case with Server 2003.

WindowsNT 3.0 Retail

Now this I would like to see, but it would be doubtful
I also think that there were more MS-DOS versions that had fat 32 compatibility and some other features. They were released only for banks and for the military and the version numbers were a between 6.23 and 6.25.

Am I missing something? The list calls Windows 95 "4.0.1111" rare. In my junk pile, I have no less than 2 real discs of this version. Possibly even a few "Companion" cd's as well.
