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).
