Windows Never Released Wiki


Windows 13 (Palisade) was the thirteenth major release of Windows. Windows 13 was intended to be a total revamp of Windows itself. Windows 13 had an all-new kernel called the Quantum Kernel intended to prepare Windows for quantum machines and to be used as a universal kernel, allowing Windows to run on any device.

Microsoft Windows 13 initially had an overwhelmingly positive reception. Many praised its fast loading time and stability and the various new features.

New features and Changes

  • A redesigned UI based on Flunet 2 design
  • An all new setup design that has been redesigned from the ground-up.
  • All legacy systems have either been revamped or removed due to the all-new-kernel.
  • "About Windows" now informs of the user of the amount of System RAM, returning a feature not seen since Windows Vista.
  • Many new apps have been added, while legacy apps have either been rewritten or revamped.
  • Many new Widgets have been added to make Widgets more multipurpose.
  • 32-Bit apps no longer run in Windows and no longer supported, and as such, System32 has been renamed to System64, while Program Files x86 has been removed.
  • File Explorer has been heavily updated to become more efficient.
  • HFD (High-Efficacy Drive) is a new file system that uses up much less of the drive and allows faster performance in an SSD. It replaces NFTS

History and Development

The idea of replacing the NT kernel had been around since the launch of Windows 12 in 2024. Windows 12 showed that the NT kernel was so old and outdated that were only two ways to keep releasing updates and versions to Windows.

One was to rewrite the NT kernel to order to modernize and futureproof it. That side became Project QNT while a team on the other side believed that NT kernel needed to be replaced with a futureproof Kernel that would need rewriting for decades to come. This project was named "Uranium."

Uranium had much better progress then QNT because Uranium had builds roll out on a weekly basis where as QNT had its first and only build roll out almost 5 months after Uranium rolled out its first build. This was likely due to the experienced Uranium Team compared to the mostly rookie team at QNT. The two projects were soon merged in early 2028 into Project Palisade to develop the next major version of Windows about a month before the unveiling of Windows 13.

Some developers of QNT were disgruntled with the merging of the two projects, and attempted to create a competing operating system known as PhoenixOS. The project recieved a poor reception before being swiftly discontinued after Microsoft sued and won.

In July of 2029, Palisade was unveiled at Microsoft's next event. At this stage, Palisade was early in its development and was mostly used to showcase The Quantum Kernel. However, Microsoft stated that Insider Preview builds would come out in the summer of 2029. Windows 13 would have the longest development cycle ever in Insider History, having over 18 Insider builds launched over its 10-month cycle in the program.


Build 27995.1000 (14-06-2029)

ISO was leaked and quickly taken down the following day. Microsoft later filled a DMCA claim on the original leaker for unauthorized leaking of software.

Build 28191.1000 (15-07-2029)

Build 28298.1000 (25-07-2029)

The first build with new features. It was the first build no longer supported 32-bit apps, as launching them would result in Error 32-BIT-NO-SUPPORT trying to load a 32-bit app. It also has the following features:

  • An early version of EdgeQ (a revamped version of Edge)

This is the third build and the first one with ISO support. Upon starting up it boots up with a warning stating,

"This build is a preview of the next generation of Windows. Do not use this as your primary OS; otherwise, you may encounter errors that may prevent crucial actions, which may cause the system to crash. It's strongly advised to use a VM in any case."

It also has more features packed in, such as Neutron, a new free photo editor that supports up to 8K and allows the importation of files from Photoshop or GIMP. As of this build, it is mostly finished except for 8K support, as trying to render 8K may result in a crash. It also has a redesigned Store that uses Fluent 2

Build 29227.1 (04-12-2029)

EdgeQ is finished at this point. While Neutron has become an app to download from either the store or the website of Microsoft, it also comes with 128-Visual, a program that allows you to program in 128-Bit, mostly for experimental purposes.

Build 29392.1 (07-12-2029)

At this point, Insider Builds would stop for one month as Microsoft would launch Updates for Windows 12.1 and Windows Infinity. Also the year was ending by this point.

Build 29499.1 (07-01-2030)

After a month of paused development, builds started to roll out once more. This build had nearly everything done at this point. It was the first build to require 1440p or 4K as a default resolution for Home and Pro SKUs. Enterprise would also require it starting with the following build after. SE would never have this required due to criticism from schools

Build 29522.1 (12-01-2030)

At this point, new features were rolling out less and updates were mostly stability-focused to get ready for the Final Release. which was now planned for April.

Build 29999.1 (22-01-2030)

This build was essentially the final product by this point. besides the fact, It had a lot of bugs left to fix. and the branding was still "Version Dev" in some places. though the final branding of Version "30H2" is mostly common by this point. Microsoft stated the reason why development had taken so long was because of the new kernel and the need to import everything from NT to Quantum. Also due to the fact this was a massive update to Windows thus requiring a lot more time to be finished. It's the last build to be launched only to the Dev Channel

Build 30000.1 (29-01-2030)

Windows 13 was announced on the Windows Channel and social media. It also formally got its final name, Windows 13. (Though Windows 13 was in the system by this point in some places).

Cumulative update with minor fixes for Windows 13.

Build 32000.1 (15-02-2030)
