Sysprep

System preparation (sysprep) readies Windows operating systems for various special actions such as taking a capture image. Sysprep is the opposite of OOBE. Sysprep removes all identity information from windows, for instance user accounts and such. Sysprep reverts the system to it's original state as if it had never been used.

You can find sysprep in the:

 %SystemDrive%\Windows\System32\sysprep/

directory.

Restart your computer and connect to your WDS server with PXE boot.

Sysprep without removing drivers

Sysprep removes installed drivers by default. After a small registry edit it will not.

Open the registry editor (regedit.exe)

Go to path

 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Sysprep\Settings\sppnp 

And change

 set PersistAllDeviceInstalls

to

1

Restart windows and run sysprep.
