I somehow lost the registry key HKLM\Software\Microsoft\Windows NT\CurrentVersion\ProfileList. In fact there is only one reg key under CurrentVersion ( WPAEvents ). So that would explain why when I log in as user "ME" the default user profile gets loaded instead of the one for "ME". Also, under C:\Users I see folders for all the user profiles including "ME" with all the files there and intact as far as I can tell. So whatever happened it seems like this is an issues strictly with registry corruption. So my questions are: 1) What might have happened to cause such corruption? 2) Most importantly what are some options for restoring the needed profile keys in the registry? Thanks for any help.
