Allow me to explain why I gave an answer that sounded rude. Based on his post:
1. There is no way to know who the OP is other that what he says. He is ready to wipe the entire disc clean. Would that not suggest he has not used the computer very much?
2. The owner of a new computer should have made a backup plan soon after the purchase. Vista has tools for making a suitable backup system.
3. By now most people are aware that computers need some kind of security. How could he forget a password if he was the one who did it recently? (Hint: try your nickname.)
4. Dell has very good support. But you have to spend some time on there web site. They know who is the registered owner. His bad mouthing appears to a subterfuge for not using the Dell resources. Dell would nail him.
5. This site gets get lots of requests for password reset and reasonable methods it can be found in a search on this site.
6. A well-trained technician who knows Dell laptops can install Vista on the laptop without the need to use a bootleg disc. The product key and the legit Dell recovery disc would be used to put the computer back to the original state.
His reluctance to pay for his alleged mistake suggests that he may not be the real owner of the computer. A sorry owner should be willing to go to great lengths to recover his system. My critical observation is only from his post and his response.
If indeed, he is the rightful owner, my apologies.
