I Never said that I used Win9X with PWS to host a Website... I am trying to
point out that Win9x users that installed PWS on there machine (either just
to see what it is) can be exposed to this hole...
I am sure that alot of PWS users are out there, not as profesional servers,
but as testing machines...
A quick ip ranged port scan on port 80 on my local ISP showed over 100 PWS
servers running with the default HTML PWS uses...
This means that users install PWS without even using it...
A Windows Update would be nice...
