QuestionWhat is a Windows SID?
Community AnswerAn SID, short for "security identifier," is a number used to identify users, groups, and computer accounts in Windows. SIDs are generated when the account is first created in Windows and no two SIDs on a computer are ever the same. The term "security ID" is sometimes used in place of SID or security identifier.
