It's a Schestowitz post, so you should invest 10 seconds with Google
before believing it. It is, in fact, wrong:
As in Windows 2000, programs can take advantage of QoS through the
QoS APIs in Windows XP. One hundred percent of the network bandwidth
is available to be shared by all programs unless a program
specifically requests priority bandwidth. This "reserved" bandwidth
is still available to other programs unless the requesting program
is sending data. By default, programs can reserve up to an aggregate
bandwidth of 20 percent of the underlying link speed on each
interface on an end computer. If the program that reserved the
bandwidth is not sending sufficient data to use it, the unused part
of the reserved bandwidth is available for other data flows on the
same host.

(Actually, you could figure out without Google that Schestowitz is
wrong, as a lot of people have had occasion to do network benchmarks on
Windows. They would have noticed a 20% bandwidth reduction).
