First rule of computer security: don't buy a computer. Second rule: if you buy one, don't turn it on.

> I would like to ask Vicky that is there anything special with the codes within the braces after ren command. Or can there be anything like such codes within those braces.

Hi Fellow Hackers,

I really appreciate the question raised by Surya Mani. As a hacker, your mind should always be set to think like an hacker, to find out the "how-and-why" of various working concepts rather than using ready made tools and applications. Now coming to the answer part, these 128 bit numbers, spelled in hex, within a pair of braces are known as CLSID. It is a globally unique identifier that identifies a COM class object.

(Don't break your head if these concepts fly over your head - these are mainly used by System Programmers and System Integration Testers - but its always good to learn as a (wanna be) hacker)

A topic on CLSID is not complete without a reference to UUID, GUID and IID. Lets see how UUID, GUID, CLSID and IID are related to each other.

UUID is the generic name for the 128 bit type which is used in COM

GUID stands for globally unique identifier and is also the name of the C union ( variant record ) which holds the UUID

CLSID is the term given to some constant and known UUIDs which are passed to the COM functions which create the particular COM object, There are hundreds of CLSIDs defined in the MS SDK header files with names like CLSID_FilterGraph etc etc.

IID refers to a UUID which identifies a partcular interface that a COM object implements. For example to find out if a particular COM object supports say the IPicture interface, you would call the QueryInterface function on it passing the IID_IPicture constant to it and if the object supports that interface you get a pointer to it.

So general term is UUID (theres a tool called uuidgen to help make such) , CLSID refers to Class IDs and IID refer to Interface IDs

Finally some CLSID's for you:
