I've recently purchased windows 7 with the high hopes of a smooth installation. Well it seems that since I'm running xp on both my computer and laptop I'm going to have to do a clean install on both. I've read through the blog, purchased an external hard drive to back up my data, but i'm neverous to wipe the computers. What all should I be backing up? What if I don't have the original disks I install my software with? What should I be backing up? Is there a recommended software? Any advice would be apperciated.
