To know which is the username associated with a known SID (Security Identifier), open the registry (regedit.exe) at this location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList.

Each SID key has a ProfileImagePath string whose value is the user path which contains the username.
To know which is the SID associated with a known username, select the ProfileList key and search the username.

There is also a SysInternals command-line utility which shows the SID associated with a known username:
