Hi DrO,
My optimistic comment was related to your last comment above and not about continued support for XP. However I expect XP uses are happy that you will try to keep Winamp running on it as long as reasonable, even though it is currently a pain to do so.
Even though she didn't say so in her comment; "I hope, Winamp & Milkdrop will work also on future Windows Versions, not only on Vista & Win7...", I'm sure that Sabine knows that Winamp is running on Windows 8 and 8.1 desktop mode now.
