Cleaning an XP install cd

Delete the SVCPACK folder (I386SVCPACK) if you don’t want to add other programs.
Also, if you want to remove unattended setup, name and company, etc. go to $OEM$$$System32 and edit OEMINFO.INI, then go to I386 and edit WINNT.SIF.

Use 7zip to extract files from the iso, edit, then create new bootable iso.
