Windows X-Lite 11: Optimize Your Old PC with This Lightweight Version

Windows X-Lite 11: Optimize Your Old PC with This Lightweight Version

31 December 2025 17:38

On December 31st, for gamers and older computer users looking for maximum performance, the official version of Windows 11 often seems too heavy. However, the famous Windows X-Lite recently released a new version based on Windows 11 26H1.

This lightweight, high-performance, customized operating system removes unnecessary system components, significantly saving memory and disk space while optimizing system settings.

High performance for older PCs

To meet the needs of different users, Windows X-Lite offers multiple versions, including the Optimum version , suitable for everyday use, which offers excellent performance and good compatibility. The Micro and Ultralight versions are more suitable for older PCs and virtual machine users, as they significantly reduce system services and maintain only the core functions, further reducing resource consumption.

However, the Micro and Ultralight versions are not recommended for everyday use due to significant performance cuts. Although Windows X-Lite enjoys an excellent reputation among overseas gamers and guarantees “100% security and cleanliness,” users should still independently assess the risks before installing it, as it is a third-party modified version.

This version allows you to bypass TPM, Secure Boot, RAM, CPU, and storage checks, as well as the forced creation of a Microsoft account during setup/installation. This ensures a smoother experience even on lower-spec computers.

This version of Windows X-Lite Optimum 11 24H2 includes:

  • .NET Framework 3.5 preinstalled
  • Windows Defender optional
  • Full and upgradeable version
  • Virtual memory enabled by default
  • Intel RST drivers integrated into the configuration
  • Includes optional system transparency
  • Extreme performance for your apps and games
  • Full support for UWP apps, Xbox, MS Store, etc.
  • Full support for additional language packs, Speech, Voice, etc.
  • Full support for all optional features, including WSA and WSL2
  • Rounded corners, acrylic and mica enabled by default
  • Further improvements and optimizations included
  • No pre-installed UWP apps

And from a licensing perspective?

Windows X-Lite 11 an unofficial, modified version of Windows 11, made by a third party and not released or endorsed by Microsoft. Installing Windows X-Lite is not strictly speaking piracy if you use a valid, genuine product key. X-Lite does not “give” Windows; it is simply a modified system image.

This is a customized ISO (“lite” or “optimized”) in which components of the original operating system are removed or altered, distributed through unauthorized channels and outside of official Microsoft networks.

Legally, using these versions violates Microsoft’s licensing terms : even though they are based on Windows 11, they cannot be considered official software. Furthermore, anyone who downloads and installs this software on a PC must still have a valid license for the original Windows , purchased through official channels.
