Can you change a Windows SID?
Table of Contents
To change a SID, you must use the Windows utility Sysprep (System Preparation Tool). This is the only method that is supported by Microsoft. For more information on using Sysprep, see this Microsoft article: How to Use Sysprep: An Introduction. Note: Microsoft does not support using NewSID to change a SID.
How do I find the SID of a Windows server?
What to Know
- In Command Prompt, type wmic useraccount get name,sid and press Enter.
- You can also determine a user’s SID by looking through the ProfileImagePath values in each S-1-5-21 prefixed SID listed under:
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList.

Is there such a thing as Sid duplication?
The final case where SID duplication would be an issue is if a distributed application used machine SIDs to uniquely identify computers. No Microsoft software does so and using the machine SID in that way doesn’t work just for the fact that all DC’s have the same machine SID.
How do I find duplicate SIDs when a disk is cloned?
Most enterprise disk imaging software provides the functionality to ensure new SIDs are generated when a disk is cloned (sysprep should also do this), but for various reasons this isn’t always done. Microsoft has a tool that can be used to find these duplicate SIDs and generate new ones.
How many subauthority values does a Windows Sid have?
At one point during the design of Windows NT, the machine SID might have been used for network identification, so in order to assure uniqueness, the SID that Setup generates has one fixed subauthority value (21) and three randomly-generated subauthority values (the numbers following “S-1-5-21” in the output).
Does Microsoft software use the same machine SID for all DCS?
No Microsoft software does so and using the machine SID in that way doesn’t work just for the fact that all DC’s have the same machine SID. Software that relies on unique computer identities either uses computer names or computer Domain SIDs (the SID of the computer accounts in the Domain).
