**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. Extension-class packages and stale duplicates are excluded. 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.
- 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.
