You can retrieve the password using Magic Jelly Bean Keyfinder. It now has the ability to retrieve passwords even from dead windows installs.
Download it from here:
Here's an extract from the site:
Load Hive option - allows you to load the registry hive of another Windows installation. To use, put the hard drive in a working machine (must also be Windows 2000,XP or Vista) or use Windows PE (not tested, should work) and click Load Hive. Then point it to the dead Windows install. If you're using Windows Vista, Administrator rights are required for this feature. You may have to right click on the Keyfinder and run as Administrator.
Hope this helps
