Not in XP, but I used a similar site for Win7
DTShellHlp.exe is Daemon Tools. You can easily stop that process, if you're not using it.
The other processes seems to be either an anti-virus or just processes I don't know about.
All of those named "svchost.exe" are Windows services, which can be read about, and turned off by following the guide in my link
