==Development==
By May 2024, Microsoft had announced a new version after Windows 12. By that, Microsoft subsequently ignores the superstition of the number "13" being unlucky due to pressure from skeptic organizations. Microsoft said that it is free to upgrade to Windows 13 in devices running Windows 11 25H2 and Windows 12, as of a fresh installation from RTM. The first version of Windows 13 was revealed as an Indev Version since December 16, 2025. By that, Microsoft is now transitioning from using Segoe UI as the main font to Montserrat in their bootscreens.
In February 2025, Microsoft released Windows Nebula with mostly with the Segoe UI Font and some changes from the Windows 12 UI. 
The Xenon Phase starts in May 2025 and ends in November 2025, as with some early confidential builds shown in PDC 2025. By the start of the Xenon Phase, Microsoft renamed "Windows Nebula" to "Windows 12X", In favor of skipping 13. 
In January 2026, When the Cesium Phase Starts, Microsoft made a final decision to name the OS "Windows 13", And entirely cancel Windows 12X. By then, Microsoft decided to bring back unique backgrounds to bootscreens, leading them to rewrite the UEFI Boot system for optimization and the adaptation to the Uranium Kernel 
In June 2026, The Final few beta builds now switches between the NT Kernel into the Uranium Kernel, which had lead some older builds before April 2026 to be binary-incompatible with each other. A Flat version of the logo is used, Until the RTM Release where Microsoft reveals the colorful logo design with Frutiger Gaia. 
In July 5th, 2026, Windows 13 was officially "Release To Manufacturing", until July 11, when general availability arrives.

==Introduction to the Uranium Kernel==
With the NT Kernel showing signs of obsolescence, Microsoft introduced a new kernel called "Uranium", which runs much faster and more efficient than the legacy NT and 9X Kernels. The Uranium Kernel is optimal for maximum performance gaming and 3D modelling, that requires a physics simulation and an array of many objects in a large scale. With the Uranium Kernel in mind, it subsequently introduces a new and more efficient hard drive called "UFS" or "Uranium File System" that can also be optimized for hard drives with 1 TB and larger. 
==New Corporate Branding==
In 2026, Microsoft introduces the Gaia Design Language, in which is more focused on bright colors and 3D ribbons, making it much more of a festive look. In that way, Microsoft adapted the Sarimanok as their mascot in their branding for Windows. The new logo is based off the stained glass windows of the Sistine Chapel, rotated and bent for more of a peacock look. Also, The Microsoft Logo is changed from squares to look more like a peacock, but still use the 2012 color scheme.
