Do you want to run F@H as a service, so it's invisible?
If so, download
this file and make 4 folders. Copy this file into each folder. Go into the first folder, double click the file, and go through the steps of typing in your username and team number. When it asks if you want to change advanced options, say yes. Accept the defaults, but when it asks "Start as a service...." say yes. When you're done with configuration and it begins to download the core, press Ctrl+C to stop it. Repeat this for the the second, third and fourth folders you created, do exactly rhe same but change the "Machine ID" from the default of 1, to 2/3/4 respectively to avoid conflicts.
Once all four setups have been completed, go to start - run - type services.msc and press enter. Find the four Folding@Home services, and start them all.
Four copies of F@H will now run in the background, with no visible indication that they're present. If you want to keep an eye on them, I recommend
HFM.NET.
If you'd rather not have them run as services, just accept the default "no" for "Start as a service..." and it will just run when you've done the configuration, however this will give you four command prompt windows for F@H.
Hope this helps.
