Hi,
Thanks for your reply I tried your program but it still happens the same. I used the repair permissions option as it says in the link you gave me. I think that's something related with windows xp x64 because in the 32bit version Ccleaner doesn find problems with this keys.
Here there is the complete list of the "rebel" keys (I forgot two of them)
