Windows 7 Installer Partition Customisation

[Cyber Axe]

Does anyone know you can, or know where i can find the relevant i for customizing the partitioning part of the Windows 7 installer

I cant find any info on this part of the setup process, does it use a diskpart script in the background or is it a custom partitioning built i to the setup and such?

The main reasons i want to play around with it:

i want to be able to customise it so i can potentially optimise it better (if it is doable i imagine it would be the same process in the win 10 installer, since it’s seems to be based on the same code and the default win10 boot partitions are done badly and it would save me manually diskparting them later)

Plus i plan on doing some windows xp installs in wim format to install via the win 7 installer And win xp requires some specific parameters for the partitioning 

Any info is welcome, thanks

WHY?

I mean , boot to a PE, do the needed/wanted partitioning, then install the Windows WITHOUT using the installer.

It's easier and faster.
