Find Security Identifier (SID) of User in Windows 10 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. Find Security Identifier (SID) of User in Windows 10 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. There are many other reasons you need to know the Security Identifier (SID) of a User, but there are various methods to find the SID in Windows 10. So without wasting any time, let’s see How to Find Security Identifier (SID) of User in Windows 10 with the help of the below-listed tutorial. Contents

Find a user’s SID with WMIC or in the registry

Updated on January 15, 2022

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

A common reason why you might want to find the security identifier (SID) for a user’s account in Windows is to determine which key under HKEY_USERS in the Windows Registry to look for user-specific registry data. Matching SIDs to usernames is easy with the wmic command—available from the Command Prompt in most versions of Windows.

How to Find a User’s SID With WMIC

Follow these easy steps to display a table of usernames and their corresponding SIDs. It’ll probably only take a minute, maybe less, to find a user’s SID in Windows via WMIC:
See How to Find a User’s SID in the Registry further down the page for instructions on matching a username to an SID via information in the Windows Registry, an alternative method to using WMIC. The wmic command didn’t exist before Windows XP, so you’ll have to use the registry method in those older versions of Windows.

  1. Open Terminal (Windows 11), or open Command Prompt in older Windows versions.If you’re using a keyboard and mouse in Windows 11/10/8, the fastest way is through the Power User Menu, accessible with the WIN+X shortcut. If you don’t see Command Prompt there, type cmd into the search bar in the Start menu, and select Command Prompt when you see it. You don’t have to open an elevated Command Prompt for this to work. Some Windows commands require it, but in the WMIC command example below, you can open a regular, non-administrative Command Prompt.
  2. Type the following command into Command Prompt exactly as it’s shown here, including spaces or lack thereof:
    wmic useraccount get name,sid

    …and then press Enter. If you know the username and would like to grab only that one user’s SID, enter this command but replace USER with the username (keep the quotes):

    wmic useraccount where name="USER" get sid

    If you get an error that the wmic command isn’t recognized, change the working directory to be C:\Windows\System32\wbem\ and try again. You can do that with the cd (change directory) command.

  3. You should see a table displayed in Command Prompt. This is a list of each user account in Windows, listed by username, followed by the account’s corresponding SID.

Now that you’re confident a particular user name corresponds to a particular SID, you can make whatever changes you need to in the registry or do whatever else you needed this information for.

Finding the Username Using the SID

If you happen to have a case where you need to find the user name but all you have is the security identifier, you can «reverse» the command like this (just replace this SID with the one in question):

wmic useraccount where sid="S-1-5-21-992878714-4041223874-2616370337-1001" get name

…to get a result like this:

Name jonfi

How to Find a User’s SID in the Registry

You can also determine a user’s SID by looking through the ProfileImagePath values in each S-1-5-21 prefixed SID listed under this key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

The ProfileImagePath value within each SID-named registry key lists the profile directory, which includes the username.
For example, the value under the S-1-5-21-992878714-4041223874-2616370337-1001 key on the computer you see above is C:\Users\jonfi, so we know that’s the SID for that user.
This method of matching users to SIDs will only show those users who are logged in or have logged in and switched users. To continue to use the registry method for determining other user’s SIDs, you’ll need to log in as each user on the system and repeat these steps. This is a big drawback; assuming you’re able, you’re much better off using the wmic command method above. FAQ
