WinSxS naming convetions

[fireatmyself]

Hello.

I'm having trouble understanding how windows searches for a specific .dll using the information found in a manifest for a certain executable file. Suppose that ia have
to load msvcp80.dll which found in directory: x86_microsoft.vc80.crt_1fc8b3b9a1e18e3b_
8.0.50727.762_none_10b2f55f9bffb8f8



Now:

• x86 (processor architecture): Built for x86 (32-bit Intel Processor and compatibles)
• microsoft.vc80.crt (name): Microsoft Visual C 8.0 C RunTime
• 1fc8b3b9a1e18e3b (public key token): A unique ID for C Runtime
• 8.0.50727.762 (version): Version of the DLL's (right click on the DLL, select "Properties", and then the "Details" tab, and you should see this number)
• none (language): The language these DLL's are designed for
• 10b2f55f9bffb8f8: ?!? what can this be ?!?

Any idea on what the last 8 bytes may represent and how to determent them?

Thank you.
