Update (02/04/2013): The typical Windows problem has befallen me. It run a variety of programs and the computer is simply slow. So much for Windows 8 and everything is better ;-). So I replaced the short term the HDD to a 128GB SSD (Samsung 840) and the speed boost is tremendous. The exchange worked without problems and I would recommend any user this step only warmly. The Samsung migration tool has the plate 1: 1 cloned and I needed this just installed.
