There are two types of install, clean (custom) or upgrade. From your commens I am not sure which one you chose. If you chose clean, everything is gone; programs, applications, mail, everything. If you chose upgrade, everything should still be there.
Based upon MS propaganda upgrades are not possible from XP to Windows 7. When they say not possible, I do not know if it really is not possible or the result would be a Frankenstein OS.
My advice if you are not happy with the outcome, try again and this time do a clean install
As far as easy transfer, apparantly, something is corrupted or not working correctly. You may have lost the files. Go to your C: drive check for a folder windows.old, that is your old files and you may be able to restore some files from that.
