I have 3.4 as base score in Windows Vista Experience Index Score (I can run AERO and Windows Switcher BTW). Windows Update released updated NVIDIA graphics driver v7.15.10.9746 so I grabbed it. Windows Vista’s score turned grey which means I need to refresh it. I did. You changed my score from 3.4 to 3.3 – what’s the deal? [8-)]

Update/Edit: 3.4 base-score returned after restarting and running the assessment again [:D]
