Since Windows 8, Microsoft uses a build number that roughly correlates to the date of compilation:
The formula is simple: Build = Days since a certain epoch + base. But the key is that builds increase monotonically. The current Windows 10 stable build (as of mid-2026) is 19045.xxxx, still in the 1904x branch. Build 23100 would be a massive jump—equivalent to jumping from Windows 10 version 21H2 directly to a hypothetical version 24H2.
Search for “Windows 10 Build 23100” on YouTube, and you’ll find dozens of videos with titles like:
These videos show fake animations, modified DLL files, or third-party software (like ExplorerPatcher or StartAllBack) dressed up as “native features.”
To understand why Build 23100 is a phantom, you need to know how Microsoft numbers its builds.
