[PANTUGGeneral] Windows reg settings for 15/2 FiOS

[JP Vossen]

For Troy, but I figured it was a useful FYI. During my 15/2 residential
FiOS install (SE PA Fall 2006) I did not get close to the full 15M
download speed until we ran the "Verizon FiOS Optimizer" on the
sacrificial W2K PC I set up for the installers to use. Naturally they
had no idea what the settings where, so I did a before/after Registry
snapshot and figured it out on another test machine, then applied this
.reg file to other machines. AFAIK, it worked, though I haven't played
with it in a while. YMMV.

Microsoft has single-handedly nullified Moore's Law.
Innate design flaws of Windows make a personal firewall, anti-virus
and anti-malware software mandatory. The resulting software arms race
has effectively flattened Moore's Law on hardware running Windows.
