CrustyWindows:What qualifies

What qualifies as a "bootleg"? This wiki and the Crustywindows collection uses the following definitions.

If an ISO matches two out of the four:

• Adds software
• Adds registry/program tweaks
• Modifies the theme
• Modifies the setup and or OOBE

then it qualifies as a bootleg under our definition. ISOs that simply add updates or drivers (i.e. Windows XP End-Of-Life Edition, Windows 7 Gen2, etc) do not qualify as "bootlegs".

Exceptions are made for any ISOs with infamy or are otherwise noteworthy, i.e. Windows Longhorn Reloaded which resulted in actual legal action from Microsoft.
