🔧 Fix: Inject Drivers into WinPE

Mount the WinPE image:

dism /mount-wim /wimfile:"\\ServeurLDMS\ldmain\landesk\vboot\boot_x64.wim" /index:1 /mountdir:c:\mount

Inject the touchpad drivers:

Dism /Image:C:\mount /Add-Driver /Driver:"c:\WinPEDriversPbTouchPadx64" /Recurse

Commit and unmount:

Dism /unmount-wim /mountdir:c:\mount /commit

Make sure the drivers in c:\WinPEDriversPbTouchPadx64 are the correct ones for your HP model.
Always back up your original boot.wim before modification.
