The article "Share files and printers between Windows 7 and XP" on this site, though impressive and promising to solve
my problem, has turned out to have feet of clay. The article's recommendations relate to Windows 7 x64 RC1, from which
Windows 7 Professional and Ultimate apparently sprung (?).
I have Windows 7 Home Premium, which, as with Vista Basic and XP Home, has limited or no workgroup capabilities. I also
have a machine with Vista Basic and one with XP Professional, to which a printer is attached. I am trying to share files and
the printer, but following the instructions in the article has not succeeded in enabling sharing.
My question is: are the limited versions of Windows 7 and Vista which I have, capable of the sharing I want? Or are they so
crippled deliberately that there's no chance of the sharing's being possible, unless I upgrade to the full versions?
