Tiny11 is an “enhanced” version of Windows 11, optimized to use minimal storage space and run efficiently on older or less powerful hardware.
Tiny11 is based on Windows 11 version 25H2, offering a clean and fast user experience by removing unnecessary apps and services found in the standard Windows installation.
Tiny11 requires about 8GB of disk space, compared to the 20GB typically used by a full Windows 11 installation. If you want an even lighter option, the Tiny11 kernel is an even lighter version of Windows 11, while sacrificing functionality. So it's more aimed at those who want something for a virtual machine or testing environment.
Tiny11 can be activated using a legitimate Windows 10 or 11 product key. Since it is based on Windows 11 Pro, activation works the same way as the official version. Tiny11 can be installed on unsupported devices and is compatible with upgrades from Windows 10.
Ο NTDEV, the programmer who develops tiny11 builder never stops making his project better and better. The Tiny11 Automated Builder It receives almost daily updates and allows you to create your own ISOs.
But if you don't like using PowerShell and scripts, you can still enjoy tiny11.

Although the press releases will range from very select to rare, I said I'd pass...because sometimes the editors hide.
