Activated windows xp (home Edition)

[Mat]

Can anyone tell me what to do after typing the wrong
product key number during registration therefore
activating windows xp without accessing the program
itself. I click start, then all program, accessories,
system tools and the system says windows has been
activated. Appreciate your help.

There is an alternative phone number on the activation window, you could use it and
explain your issue or go here for other options

Sounds like you accidentally "cracked" XP.
