Also, some Linux distributions can automatically mount all Windows partitions after the system is installed, such as "Red Flag 5.0". In our study ...

A few weeks ago, I published a blog about Windows Azure cloud services. I'm digging up new things and experimenting with mac,pc and Linux (I prefer Ubuntu).
