xp to win7

My old XP crashed, I was able to save everything but the OS and just did a clean install then added NIS.  The product loaded correctly and is working perfect but I would like to know if there is any way possible to recover my login account stuff I had that managed all my passwords?  I know with ms outlook when I installed office on the new build all I had to do was set up a email and move the data file to the correct location and bam I had all my emails..  Please tell me we can do this with NIS :)  thanks
