GetSID - get unique Windows ID

Gets a Window's system SID (unique computer ID)

GETSID scans the Windows registry for the SID data, and returns it if found. This is useful in cases where you wish to limit or change functionality for specific computers, and need an identifying ID. It is also a simple example of accessing Window's registry.

GETSID is equivalent to Microsoft's PsGetSid utility (http://www.microsoft.com/technet/sysinternals/utilities/psgetsid.mspx).

GETSID requires Microsoft Windows and works on Matlab 6 and up.
