Ah,finally its gone. I reclaimed my ownership and deleted those accounts. However,I can't still understand why this unknown username was present there. Has this happened with thy computer before?

Probably. I usually just delete accounts that I don't recognize. Sometimes software installations will create accounts like that. If everything else is operating OK, then I wouldn't worry too much about it. I would just check over the next few weeks to see if they reappear. If so, then a lookup of the GUIDs in the registry would be in order.

The GUID is a Global Unique IDentifier. It's that S-1-.... part in the parenthesis. The Windows registry heavily uses that to uniquely identify things. If you search for the GUIDs from the unknown users, you'll probably find that it references some software that you've installed.

Was this computer ever part of a domain?
When a domain system is disconnected from the network, account information cannot be retrieved because the computer cannot reach the active directory for user info.
