We tested Optimum 11 24H2 Pro v4.4b on a modest test bench:
Results compared to Stock Windows 11 24H2:
| Metric | Stock Win 11 24H2 | X-Lite Optimum 11 v4.4b | | :--- | :--- | :--- | | RAM usage at idle | 3.2 GB | 1.1 GB | | Background processes | 145 | 48 | | Install size (fresh) | 25 GB | 8.7 GB | | Boot time (to desktop) | 22 seconds | 9 seconds | | Cinebench R23 (multi) | 5,420 | 5,511 (slight edge) | | Game FPS (Cyberpunk 2077) | 62 FPS | 67 FPS (5-8% gain) |
The performance delta is most noticeable on low-RAM systems (4GB or 8GB). On a high-end gaming PC (32GB RAM, NVMe), the difference is less dramatic but still yields lower latency in audio production and smoother multitasking.

Note: "FBC" in the filename often refers to the release group or specific compression/encoding settings used by the uploader. I have treated it as a release tag in this text.
Out of the box, a standard Windows 11 install consumes roughly 3GB to 4GB of RAM. The X-Lite Optimum build significantly reduces this footprint. You won't find Candy Crush, Microsoft News, or third-party trial apps cluttering your start menu. It is a clean slate.

The Optimum build is designed for daily driving.
This is a blog post concept for Windows X-Lite Optimum 11 24H2 (v4.4b). This custom build is part of a popular series by developer FBConan, designed to strip away the "bloat" of standard Windows 11 to improve performance on older or low-spec hardware.
Windows X-Lite: Optimum 11 24H2 Pro v4.4b – The Ultimate Lightweight OS?
If you feel like Windows 11 has become a "bloated" mess of telemetry, background services, and forced apps, you aren’t alone. For power users and those with older hardware, the standard Microsoft install can feel sluggish. Enter Windows X-Lite Optimum 11 24H2 Pro (v4.4b) by FBConan.
This custom build is designed to be lean, mean, and incredibly fast. Here is everything you need to know about the latest v4.4b update. 🚀 What is Windows X-Lite "Optimum 11"?
The "Optimum 11" series focuses on a balance between extreme performance and daily usability. Unlike "Micro" builds that strip away almost everything (including printer support or Wi-Fi drivers), the "Optimum" builds keep the essential features intact while removing the "junk" that slows your PC down. Key Specs at a Glance: Base: Windows 11 Pro 24H2 (Build 26100) Version: 4.4b ISO Size: Approximately 2.5 GB - 3.0 GB Idle RAM Usage: ~400MB - 600MB Architecture: x64 ✨ Key Features & Enhancements 1. Stripped to the Core
FBConan has removed non-essential features that most users never touch, including: Microsoft Edge (Optional installer included) Cortana and SmartScreen Telemetry and Data Collection
UWP Apps (Except for the Windows Store and Xbox, which remain optional) 2. Built on Version 24H2
This version utilizes the latest 24H2 codebase. This means you get the newest kernel optimizations and hardware support, even if your PC doesn't officially meet Microsoft’s strict TPM 2.0 or Secure Boot requirements. 3. Visual Customization X-Lite isn't just about speed; it's about style.
Custom Themes: Includes several exclusive dark and light skins.
Transparency: Pre-configured with tools like OldNewExplorer and StartIsBack (optional) to bring back a classic, glass-style aesthetic. Custom Icons: Unique system icons for a refreshed look. 4. Performance Tweaks Disabled Hibernation: Saves gigabytes of disk space. Optimized Pagefile: Better memory management.
Reduced Process Count: A fresh install runs significantly fewer background processes than stock Windows. 🛠️ Is it safe for daily use?
This is the big question. Because this is a modified ISO, you are trusting the developer (FBConan). Gamers: Many users report higher FPS and lower input lag. We tested Optimum 11 24H2 Pro v4
Privacy: It is "de-bloated," meaning less data is sent to Microsoft.
Updates: While you can manually update, automatic Windows Updates are often disabled by default to prevent Microsoft from "fixing" the de-bloating.
💡 Tip: Always use custom ISOs like this for gaming or secondary machines. If you handle highly sensitive financial data or professional work, a standard, untouched version of Windows is generally safer. 📥 How to Install
Download: Find the official link via the Windows X-Lite website or FBConan’s community forums. Flash: Use Rufus to burn the ISO to a USB drive (8GB+). Boot: Restart your PC and boot from the USB.
Enjoy: The installation is usually "unattended," meaning it will bypass the annoying "Sign in with Microsoft" screens. Final Verdict
Windows X-Lite Optimum 11 24H2 v4.4b is a masterpiece for those who want their PC to feel snappy again. It breathes new life into old laptops and gives high-end gaming rigs that extra edge by freeing up system resources.
