sharepoint pre-requisits installation

Trting to install sharepoint 2010 on Windows Server R2 Standard.

When running the install pre-requisits I get:

if I restart it continues the install and produces the same result. Always an error on the IIS config saying that it needs to restart. I did it over 4 times.

The log contains the following:

Run windows update and get all updates for your 2008 R2 server.

It's the first step before installing SharePoint 2010.
