The latest version (from my devise manager) from MS is:

Digital Signer: Microsoft Windows
The version "Webadict" is directing you to is:
RELEASE DATE: June 22nd 2009
DRIVER VERSION: R 2.27

As you can see the first is the newest release from MS.
Did a Google search and came up this one: Realtek HD Driver 2.27 (the newest release) Not sure how this will coincide with the latest MS release, however, you might want to give it a go.
