Does GUID change on update?

So I am getting the GUID number and using it in my application for some stuff and checking processes with database. But I don't know whether the GUID stays the same or changes on updates, because if it changes - I will have to rewrite parts of the program, and I don't want to do that.

I mean - I have already published and given the product to the client (with some GUID), but after some time I make some changes to the software, and provide it as update of the product, to the client. Does the GUID change then or it stays the same?

No. It doesn't change. Actually, the significance of the GUID comes into picture if the assembly is made COMVisible. AssemblyInfo.cs file gets generated at the time the project is created. And GUID in that doesn't change automatically.

Well it depends on how big the update is... I would say no, it do not change... If we are talking about product GUID it should change on release of new version of products...
