CCleaner v2.25.1025 Deleted Registry keep reappearing

Dear all,

I am using CCleaner v2.25.1025, WIndows XP Service Pack 3. I took notice that whenever I scan my registry, clean it, the supposedly deleted entries keep reappearing whenever I restart my computer. Could anyone please help me to fix this problem?

Thank you beforehand.

Yours sincerely.

All of the entries or just a specific one?
