I think I already explained, maybe not.... The OEM version the manufacturer
has installed already has SP1 integrated. This is the software Microsoft
supplies the manufacturers on their newer machines. There is no way to
uninstall SP1. At least that is what Acer (the tech) and a FAQ from
Microsoft. The only way, is to do a clean install of VISTA, which would
wipe out all of the OEM's installed software, drivers, etc.
