How to create a win7 installation with all the necessary applications???

How can i create a bootable windows 7 clone or installation with all the necessary applications and settings installed.
I tried with vLite but it only streamlined the installation but i could not intergrate applications such as Office and Antivirus.

Please help me, i need do this to make for my computer lab, i have 32 workstations and i want to make installation easier for me..

Thank you all in advance..
