The new Dell XPS Studio 9100 has arrived. It has been about 8 years since I have migrated to a new PC, new OS, etc, and I am out of practice. I am migrating from XP SP3 to Windows 7 Home Premium 64 bit, and I would like to be able to seamlessly integrate some old favorite apps into the new system. Is there a painless way to do this? I'm planning on keeping the old Dell Dimension 8400 as an emergency backup, but there are a LOT of installation disks and documentation that has gone missing, since my wife and I moved here about 6 years ago. Plus, I have no idea if W7HP has maintained backward compatibility to the XP OS. Any advice will be appreciated.
