i have a product key but no cd where can i obtain a working virus free iso?
Where did you hear that? I have two original Windows XP Pro CDs. When I installed them I had to activated them within 30 days. After that it wouldn't let you log in until I activated them.XP Pro isos like that work very well and most of the time don't require activation. I don't know if the the OP would use it though. Depends on how he looks at piracy I personally don't care and would use it without remorse.
