One of the most useless, slow and annoying features in Visual Studio.NET (2003 included) is its crappy "dynamic help" feature. It cripples the IDE performance, adds horrendous I/O overhead, pops up on top of the property sheet constantly and is completely useless to boot.

Gladly Fabrice managed to Come up with a way to get rid of it completely! Good riddance to bad rubbish. (Note that the registry change should be made in HKCU and not HKLM)

Update: Alternatively, go ahead and download VSTweak. It does the above and other things as well.
