Hi Maurice, My PC is running sluggish and I came here looking for answers and found this thread which matched a concurrent problem I have. I am running Vista 32 bit and have almost exactly the same problems and probably the same culprit - System Mechanic. I started getting code 641 at about the same time on the 10 May 2012 Failed security updates were for .NET Framework (3 of them) and Silverlight but after doing some forgoten half baked solutions from elsewhere on the internet it does not come up on the list anymore, not that it was successfully updated. My question is: Will your instructions above work for Vista 32 bit too? Thanks in advance.
