I've used earlier versions of this software and it has been effective. However, moving my XP machine to Win7, PCMover just isn't up to the task. I tried five times and after waiting more than 24 hours, I get a message that it didn't transfer! Customer service is a joke. They say to look at the quick start guide. I don't know if it's Microsoft or LapLink, but they should just not sell the product if it doesn't work.
