Transformation pack

Transformation packs are programs which transform an existing Windows or Linux install into a crusty bootleg. These bootlegs are different in that they don't (usually) come in an ISO format, but instead require the user to run an executable/script on an existing installation. A few bootlegs run a transformation pack executable on first bootup to transform the OS, while some come already integrated with the OS.

An example of transformation packs being used in a bootleg is Quelitu for Linux, and Windows 2002 for Windows XP, while an example of an independent transformation pack (i.e. one that is installed onto an already existing install) is Moebuntu for Linux, and "Windows 8 Transformation Pack", created by Windows X (one of the most popular transformation pack creators of the time).

Transformation packs are not typically archived in the Crusty Windows collection, though exceptions are made for notable ones such as BedOS.
