I run Win x64. I was also trying to get MS to give me a downgrade since there were no x64 drivers for my Oki C5300n page printer. The last thing MS told me to do was fill out a form they emailed me and fax (why not email?) it back. This was about a month ago and I haven't heard a thing. But I stopped pursuing it because I decided to try something I had done in the past (and forgotten..duh). I installed an x64 driver from the x64 install (manual selection using the 'Add Hardware' wizard) for a similar printer, the C7200. That worked like a charm. I still have no drivers for my scanner; but I can do without that since I rarely have need for it. And I still have no anti-virus software that supports real time detection (I do a manual scan every so often). I do use Windows firewall and MS Antispyware.
