John's SID does not end in -500, indicating it is a standard user account and not the built-in Administrator.

Rebecca's SID does not end in -500, so it represents a standard user account without built-in Administrator privileges.

Sheela's SID does not end in -500, identifying it as a regular user account rather than the system Administrator.

Shawn's SID does not end in -500, meaning it is a standard created user without built-in Administrator rights.

Somia's SID does not end in -500, so it is a normal user account and not the built-in Administrator.

In Windows, every SID ends with a Relative Identifier (RID). The built-in Administrator account is always assigned RID-500, regardless of the machine or its name. Chang's SID ends with -500, which uniquely identifies it as the built-in System Administrator account. All other accounts with RIDs of 1000 or higher are standard user accounts created after installation.

Micah's SID does not end in -500, identifying it as a standard user account rather than the built-in Administrator.
