[vox-tech] Search Warrant Question re: GUID

I'm trying to understand the notion of a GUID as used in a search warrant for 
child pornography.  In fact a GUID has nothing to do with the case in which 
the defendant is charged with possessing child pornography.  The police 
officer who drafted the warrant has a section discussing various high tech 
issues that were not used in the case.  But I'm just trying to learn this 

Below is an excerpt from the warrant.  "CPS" refers to a software program used 
by the police in child porn cases.

"CPS will also keep a record of each time an IP address is identified as being 
a download candidate for suspected child pornography on the Gnutella network.  
CPS also keeps record of each time a users GUID (Globally Unique Identifier a 
special type of identifier used in software applications to provide a unique 
reference number) is identified as being a download candidate for suspected 
child pornography on the Gnutella network."

Later in the warrant we have this:

"An investigator, using the CPS software, can also generate a historical 
report showing the dates and times that a specific GUID was logged on the 
Gnutella network, the IP address used and the SHA 1 hash values of any 
suspected child porn images or videos shared by that computer."

I've been Googling "GUID," and I see that there are various uses of GUIDs.  
But it's not crystal clear to me how it works in child porn investigations.  
Does it mean that a person's Limewire program has a unique GUID, that is 
different from another copy of the Limewire program?  Or is it that the 
person's version of Windows has a unique GUID that is different from mine?

Do Linux and open source programs have GUIDs, or is this just a Microsoft 

Thank you.
