Do you know exactly which processes are running on your computer? What about all the services running in each of those processes? It’s important to know exactly which processes are running on your computer, not just for security reasons but also for troubleshooting. The problem is sometimes it’s hard to tell if a process is really needed or the service with which it’s associated. The example in the following script displays a list of processes and all the services running in each process. This script can be useful to determine not only the processes and the services running in those processes but also to determine the exact service that’s associated with each “svchost.exe” listed in the Task Manager. Here are a few examples to help you understand how this script can be useful.<\/p>\n
Let’s say your Task Manager shows you a process running called Rtvscan.exe<\/strong> with a Processor ID (PID) number 536. Running the script will show you the process ID 536 is associated with Symantec AntiVirus Client<\/strong>. Or you might see a process CDANTSRV.EXE<\/strong> with a certain PID number. The script will show you the process is part of C-DillaSrv<\/strong>, which is a part of MacroVision safeCast copy protection software. The service is used to provide software activation services and CD Key verification services for anti-piracy reasons and it is bundled with several products. It also increases the amount of popups you receive on your computer. Most people will disable this service, unless the service is required for certain games.<\/p>\n You may have noticed several processes called svchost.exe, each with its own PID number. Running the script will show the exact services running under each of those processes. For example, one process may only be running Remote Procedure Call (RPC), while another svchost.exe could be running close to 30 different services. Once you know what processes and services are running, you may want to shut down the ones you don’t need.<\/p>\n
