Dear Subhash..Once i am at logon screen..I pressed CTRL+ALT+DEL key combination..but it doesnt work.. Is there any other way that i can login once and then try to solve the issue.. Thanks for reply..but it doenst work for me..

Which login screen it is ? Classic Login or welcome screen type.If its Classic login screen then you should try few usernames like administrator etc with blank password. otherwise see if you can get a live CD like Barts PE and check the registry offline. Still problems then It would be better to do a WIndows Repair using Windows CD. Subhash Chandra.
