Main Features

• Increase memory support for 128 GB for x86 and 2 TB for x64 by default;
• Allow support for run newer programs designed for modern Windows OS;
• Allow support for new hardware with new drivers controllers;
• Multi-language support for all Windows XP and Windows Server 2003 supported languages;

Before Using This Software

This software utilizes modified files from the respective systems, and also includes files that are still in the testing or experimental phase, and is developed by a single person. Consequently, predicting all possible scenarios across various computer configurations or virtual machines is not feasible.

The transition between Windows XP/2003 and Vista marked a significant leap in the development of new APIs, technologies, and modifications to existing APIs. This makes it challenging to achieve the same level of compatibility between NT 5.x and NT 6.x systems.

I kindly ask you to remain calm and cautious. Before concluding that the software is flawed or "of poor quality," please report any issues you encounter through the Github Issues or Discord server.

Please note that I cannot guarantee that all issues will be resolved. However, I will analyze them and make every effort to correct them.

Your help is valuable, and complaints or negative feedback do not contribute to the improvement of the product.

• Youtube on Firefox Starting version 131 not work. So, we recommend use version 115 or 128 ESR.
• Some applications installers may not work, like some electron based apps (MS teams), Office 2013 or GIMP 3.0 RC2 etc crash and application isn't installed. Some installers and applications require AVX support by OS, what isn't supported at no. The, use a pre-installed version, copied from other operating system;
• The packages cannot be integrate with nlite to Windows ISO, because use a tool called "SFXCAB Substitute", not standard Microsoft version;
• Standard .Net Framework Installers starting 4.6 ins't supported for now. You need a repacked version like did here: https://github.com/abbodi1406/dotNetFx4xW7. And avaliable like here: https://www.wincert.net/forum/topic/13805-microsoft-net-framework-472-full-x86x64-incl-language-packs-by-ricktendo/#comment-123251. Other versions are avaliable too, search on forum topics;
• New versions of palemoon may face side by side configuration error issue.;
• Opera 39 - 50 may need follow parameters to start: --disable-gpu (to prevent black screen) and --single-process(to prevent eternally first page loading);
