- Build String: 22631.2428 (KB5033375 or similar cumulative update range)
- Key Milestone: This is a post-“Moment 4” update, meaning it includes all major 2023 feature drops (Copilot preview, native RAR support, advanced RGB controls, and the new File Explorer) – but crucially, before the heavier “Moment 5” background telemetry and widget overheads started creeping in.

Notable changes and features
- Leaner service set: several noncritical services are disabled by default (telemetry throttled, background indexing tuned, some unneeded telemetry/diagnostics deferred).
- Streamlined shell components: trimmed default widgets and live content; some visual effects disabled to save GPU/CPU.
- Faster first-boot and resume: fewer background tasks during boot/resume to shorten time to usable desktop.
- Compact OS storage: reclaimed disk space via more aggressive component compression and optional feature removal prompts.
- App launch caching improvements: optimized prefetching for the most-used apps to reduce cold-start times.
- Power-profile optimizations: new default power plan tuned for “ultralight” consoles—aggressive CPU frequency scaling and more conservative refresh rates when idle.
- Optional modular features: users can add back functionality (search indexing, widgets, language bundles) via Settings → Optional features without full reinstall.
- Security: Microsoft Defender still included; some cloud-connected features are optional/disabled by default but security baseline remains intact.
- Enterprise controls: Group Policy/MDM options to set ultralight mode, re-enable services, or allow selective component installation centrally.
