**MinderiaOS Milestone 1.2.1 (Build 28469)** — internal pre-release test build (x86 bootcd), derived from ReactOS 0.4.17-dev (rev 1340-gfaa2d03). The ISO ships as 32MiB parts (.part00-.part17) with parts.checksums — reassemble with `cat MinderiaOS-Milestone121-Build28469-x86.iso.part* > MinderiaOS-Milestone121-Build28469-x86.iso` (whole-file md5 in parts.checksums). **HEADLINE — the centered taskbar now renders correctly, WITH the Start logo.** Milestone 1.2 shipped a centered taskbar whose Start logo could draw misaligned or blank. 1.2.1 ships MinderiaOS Shell 1.2.1 (mindshell.exe): the logo is a pre-composed offscreen bitmap, the whole bar is double-buffered (flicker gone), the start menu carries Files / Command Prompt / About MinderiaOS / Restart / Shut Down, task buttons handle focus + minimize, and a live clock sits on the right. **Other changes**: winver.exe rebuilt (PE32; PE64 in the build kit) with the M1.2-style red confidentiality disclaimer above the license line; new default wallpaper Confid-M121.png (black-gradient internal-test notice); build stamps 28469 / 28469.minderiaos_m121.261108-1150 in hives + registry.inf; Shell=%SystemRoot%\mindshell.exe; reactos.cab rebuilt so setup installs the new shell + wallpaper; rebranded FreeLoader menu, autorun label, mango icon. **Booting**: BIOS El Torito (FreeLoader) — "MinderiaOS Live Environment (Graphics Mode)" goes straight to the live desktop; "MinderiaOS Setup (Text Mode)" installs. UEFI (IA-32) image included. Isohybrid MBR (type 0x96) for USB dd. **Verification**: all 1,220 files re-extracted from the finished ISO and md5-matched; pycdlib structural validation passes; hives re-parsed and value-verified; mindshell/winver import only KERNEL32/USER32/GDI32 (ReactOS-safe); boot images byte-identical to the upstream base. **Provenance**: the earlier minderiaoos-* items (M1/M1.1/M1.2) were deleted server-side, so this is a fresh fully-rebuilt lineage from the current upstream base — sizes/file counts differ from old announcements. **Confidentiality**: internal test build for Minderia personnel and authorized Axiana partners only — do not redistribute.
