VS 2010: Disable Fileheader for new class files

I recently noticed that Visual Studio 2010 (Professional) inserts a FileHeader automatically in new class files. I don't know when this started but some time ago this wasn't enabled. Also, since then the using directives are added after the namespace.

This is the way the file looks like after generation:

// -----------------------------------------------------------------------
// <copyright file="Class1.cs" company="Microsoft">
// TODO: Update copyright text.
// </copyright>
// -----------------------------------------------------------------------

namespace MyNamespace
{
   using System;
   using System.Collections.Generic;
   using System.Linq;
   using System.Text;

   /// <summary>
   /// TODO: Update summary.
   /// </summary>
   public class Class1
   {
   }
}

And thats the way it should look like (and how I want it):

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace MyNamespace
{
   public class Class1
   {
   }
}

I disabled all extensions and all plugins, but the problem stays. Hopefully anyone here can tell my how to restore the previoous behaviour.

Thanks in advance
