| Feature | Description | |---------|-------------| | | Once installed, activation persists indefinitely; no need to reconnect to the internet or reactivate periodically. | | Offline operation | The loader works entirely offline; it never contacts Microsoft servers for validation. | | Automatic system detection | The tool automatically identifies the installed Windows edition and applies the appropriate SLIC and certificate. | | Supports 32‑bit and 64‑bit | A single installation file works on both x86 and x86‑64 architectures. | | Multiple OEM certificates | The loader includes SLIC certificates and serials for dozens of manufacturers: Dell, HP, Lenovo, Acer, ASUS, MSI, Panasonic, Viewsonic, Fujitsu, Toshiba, and many others. | | GRLDR integration | The loader uses a modified version of the GRUB Legacy bootloader (GRLDR) to inject the activation code before Windows boots. | | Safe mode installation | Later versions (including the 2.1.x branch) allow installation even from Windows Safe Mode. | | Custom SLIC positioning | Advanced options allow the user to set a custom memory location for SLIC emulation — useful if the default location conflicts with other software. | | Debugging tools | The utility can display motherboard information and system serials to help diagnose activation failures. |
