### Driver Injection Feature
**Optional Enhancement**: When enabled, exports all drivers from the running system and injects them into both:
- `install.wim` (main OS image)
- `boot.wim` index 2 (Windows Setup PE environment)
**Optional Enhancement**: When enabled, exports all drivers from the running system and injects them into:
- `install.wim` (main OS image), excluding stale duplicates
- `boot.wim` index 2 (Windows Setup PE environment), storage controllers only (`SCSIAdapter` / `HDC`)
**Use Case**: Enables offline installation on systems with missing drivers.

**Optional: Driver Injection**
- If enabled, WinUtil exports the drivers from your current system, stages boot-storage drivers for Windows Setup, and injects eligible packages into the selected `install.wim` image. Stale duplicate packages are excluded before injection. Each remaining package is added separately, so one incompatible package does not stop the others. If a package fails, WinUtil discards the partial mount and retries the remaining packages against the original image. Check the live log for warnings: if every package fails, WinUtil keeps the original `install.wim` and still produces the ISO.

A live log shows progress as each step completes. This stage usually takes **10–30 minutes** depending on disk speed. The WIM dismount near the end is the slowest part, so do not close WinUtil while it is running.
