You can find out what those processes are by going to ProcessLibrary and typing in the process name.  This site will give you a description of what it's used for and its recommendation of whether to delete it or not.  Keep in mind that it's their opinion about disabling an object.  Always do your research first.

Hello,  I  use a program called,"WindowsTasks Manager 5"  it will list  all your Running processes and  when you right

             click onto each one it will  show you a short detailed  job description of  the selected processes, you can then

              decide what you wish to do with it, but  always REMEMBER  if you are not ABSOLUTELY sure if you should

               Delete it safely,  then DON'T  DO  IT,  if it is a process which you understand  the description that is given for

               it, and  you safely know that you don't  need  or  want  it, then its your decision to  delete or leave it alone.

              

              I  find this program helps me very much however, I do not have a direct link to it, so you have to scout for it

              via  a Search engine.

 

              But  here is a Direct Link to a website  that  does describe  many, many  computer processes, good ones,

              bad ones,  necessary ones,  spyware, malware, viruses, etc.  when you click onto to it, scrool  all the way

              down  the page  and  read  everything,  should  help you  quite a bit,  OK.  here it is:

             Another  very good  thing I do, is go to your  GOOGLE  Search   and  type  in  any of your Running processes and

             it  will send you  to a site  with really good descriptions,  these are  the things that I use and they help me  a lot.

             Try  each or  all,  Hope it  helps  you,  

First of all 40 - 60 process is typical, check the Windows XP forum which has had many discussions on this topic.  Numbers in a vacuum are meaningless.  Even if you were reduced your process twenty processes, all you need is one out-of-control process to cause you problems.  At the moment I have 66 processes in my process list.  The question you need to answer is what processes are using what resources, and how much of the available resources total are you using?  Look at the task manager performance tab.  What is your CPU Usage?  What is your Commit Charge?  How much physical memory is available?  Lastly the specification of your PC would help.
