AFAIK Sempron is taking over the 754 socket exclusively and thus being a budget interface would not receive a dual-core version. That'd be like AMD selling a Duron MP.
I've got a machine that I need to extract an XP CD key from, but Windows is completely non-bootable. No safe mode, either. I need a way to extract the CD key using a commandline tool, if it exists. What are my options?
