Windows 7: Rookie mistake, can I recover?

So I upraged from Vista Home Premium to Win 7 Professional. I backed up all my documents and was plretty pleased with myself. Then got to an "oh ****" moment when I realized that I did a "clean install" and did not backup my Outlook 2007. I realize I may be screwed but I'm hoping not. I'm hoping I can find the .pst files in the windows.old folder that was created. Can anyone tell me if this is correct? Or if I need to do something else? Or if I am indeed SOL?

Thanks for your help!

You should be able to search the windows.old folder using windows explorer (or the command prompt) for *.pst and locate it/them. And yes, Outlook files should be there.
