Hi. i was restoring thinkpad laptop and other laptops to factory default state. After XP was restored, it moved to application script installation. I saw a dos-command was doing the work in the background. The script automatically install all the applications. That was nice. Can you guys tell me what script language can do the same? i want to learn script to install driver, application, configuring xp and vista desktop environment. Which script language is able to do all these works for xp, 2003, vista and (and for future os, window 7)? ?
