If you are trying to rename user profile folder or to change some registry specific data for the current user, then you might want to find the Security Identifier (SID) for that user account to determine which key under HKEY_USERS in Registry belong to that particular user account.
A security identifier (SID) is a unique value of variable length used to identify a trustee. Each account has a unique SID issued by an authority, such as a Windows domain controller, and stored in a secure database. Each time a user logs on, the system retrieves the SID for that user from the database and places it in the access token. The system uses the SID in the access token to identify the user in all subsequent Windows security interactions. When a SID has been used as the unique identifier for a user or group, it cannot ever be used again to identify another user or group.
