Where are iPhone backup files stored on my Windows computer?

The location of the iPhone backup files generated in iTunes is the following directory:

Windows XP:
\Documents and Settings\USERNAME\Application Data\Apple Computer\MobileSync\Backup\

Windows Vista or Windows 7:
\Users\USERNAME\AppData\Roaming\Apple Computer\MobileSync\Backup\

Replace USERNAME with your personal account name.

Assuming you have older backups:
Mac OS: ~/Library/Application Support/MobileSync/Backup
Windows XP: %AppData%\Apple Computer\MobileSync\Backup
Windows Vista: %AppData%\Roaming\Apple Computer\MobileSync\Backup
Windows 7: %AppData%\Roaming\Apple Computer\MobileSync\Backup
Go onto iTunes, right click on your device on the left-hand side bar, and their should be an option 'Restore From Backup', or something similar, click that and it'll restore your iPhone to a previous backup.
