Windows Vista is now loaded and validated ... there was a problem with the Knowledge Base files - 45 of them - some of which had failed. They are now on and we're coming to the end of 125 Windows updates ... and they have taken about 5 hours. If the pc survives this, then tomorrow is when we start loading on the various drivers and programs and rebuilding the whole cosmos. My resident technician has proved his worth - I've fed him lasagna and garlic bread tonight. God help us all!
