Non hai detto che problemi riscontri, comunque il log è pulito, però devi installare il Service Pack 3 altrimenti non puoi più aggiornare XP. Vai su Windows update e cercalo.
Devi aggiornare Java, vai QUI dopo un pò apparirà la finestra che ti indica se la vs è aggiornata o no.
Ci sarebbero anche troppe voci in avvio, molte sono da eliminare.
Ciao

Installa il S.P. 3 e aggiorna Java probabile che il tuo problema si risolva.
Poi devi disattivare il Tea Timer in SpyBot così:
Apri SpyBot in modalità avanzata (menù modalità - avanzata) poi vai in utilità - resident e togli la spunta a TeaTimer, e riavvia il pc.

Io eliminerei le seguenti voci.

Chiudi tutti i programmi e disconnesso lanci HJT e clicca sul secondo pulsante: Do a system scan only poi metti la spunta alle voci che ti indico e alla fine clic su Fix checked:

Alla fine fai una pulizia con Ccleaner QUI compreso il Registro, per il registro spunta tutte le voci, acconsenti il backup.
Il pc dovrebbe velocizzarsi. Ciao
