Build a smaller Windows 11 ISO with a native WinUI app. Download an official Windows image or use your own, choose what to remove, and create your ISO.
Choose x64 for Intel/AMD PCs or ARM64 for Windows on ARM. Extract the
entire ZIP and open Tiny11Builder.exe. Administrator approval is required.
| Mode | What it does |
|---|---|
| Tiny11 | Removes bundled apps and unwanted features while keeping updates, Defender and recovery. |
| Tiny11 Core | Trims further by removing servicing and recovery support and disabling Defender. |
| Custom | Choose individual apps, components, features and services to remove or keep. |
Turbo mode speeds up image processing. Interrupted builds can resume from saved progress after the image is committed or compressed. Core and component-store removals automatically use the legacy Windows installer.
Core cannot be updated or serviced. Protected Custom removals can break Windows. Test your ISO in a VM before installing it.
