I have to give it to Microsoft, they can screw up simple things, even in 2009.  So far with Windows 7, it has ‘lost’ the printer once already  (had to reinstall) and our USB scanner does not work (for 32 or 64 bit versions) .  Let’s see, Mandriva 2010 has never lost the printer, and the scanner works perfectly.  Come on, this is 2009, you have been making Windows for 20 years.  Fix it.
