I had a look and I don't have any NVIDIA Update files on my pc. I have NVIDIA Geforce 7900 GS card.
Only you can decide if you need it at all. What is NVIDIA Update It might be in your Control panel, Add/Remove Programs.
I note the 'Vista 64bit' (for 64bit) and the 'x86' (for 32bit) don't know what you are running.
