What does version info mean in Visual Studio About Box?

In Visual Studio 2005's About Box, the installed products have a (version?) number associated with them. A couple of our dev machines differ:

Microsoft Visual Studio 2005
Version 8.0.50727.762  (SP.050727-7600)
Microsoft .NET Framework
Version 2.0.50727 SP2

Installed Edition: Professional

...
Microsoft Visual C++ 2005   77626-009-1423927-41076
...

and

Microsoft Visual Studio 2005
Version 8.0.50727.762  (SP.050727-7600)
Microsoft .NET Framework
Version 2.0.50727 SP2

Installed Edition: Professional

...
Microsoft Visual C++ 2005   77626-009-1423927-41911
...

Does anyone know the difference between 41076 and 41911?

All services packs and s开发者_如何学Goecurity updates are exactly the same on the 2 machines.

Cheers.

Those numbers look more like product ids (PID) that version numbers. If they are product ids, they are probably different because a different installation set/disk was used to install Visual Studio on the two machines.
