Answer 1

ATL::CAccessToken accessToken;
ATL::CSid currentUserSid;
if (accessToken.GetProcessToken(TOKEN_READ | TOKEN_QUERY) &&
    accessToken.GetUser(&currentUserSid))
    return currentUserSid.Sid();

Answer 2

I found another way to get SID:

System.Security.Principal.WindowsIdentity id = System.Security.Principal.WindowsIdentity.GetCurrent();
string sid = id.User.AccountDomainSid.ToString();

Answer 3

in cmd.exe

whoami /user

if you need it programatically, please ask more specified

Answer 4

This should give you what you need:

using System.Security.Principal;

...

var sid = WindowsIdentity.GetCurrent().User;

The User property of WindowsIdentity returns the SID, per MSDN Docs

Answer 5

This one is the shortest of them all I believe.

UserPrincipal.Current.Sid;
