Windows processes running in the background
The desktop on your PC is misleading. What you seem to be peaceful, orderly environment is a mask that hides the chaotic dance of dozens of concurrent processes running in the background. Most of them are necessary for the correct use of the computer, some are simply unnecessary and a waste of resources on your system, but some can be harmful applications. Protect your computer from viruses, spyware and other unwanted software requires more than having the latest firewall ormost current antivirus software in place. To protect your computer and personal information, you need to know exactly what is running on your computer.
The first step is to look at all the processes running. To do this, thanks to the Processes tab in Task Manager. If you use Windows XP, simultaneously press the Ctrl-Alt-Del or right click on the taskbar at the bottom of the screen to open the Task Manager. In Windows Vista, you can either simultaneously pressing Ctrl-Shift-Esc,or right-click the taskbar at the bottom of the screen.
You are now presented with a long and somewhat mysterious, a list of all programs that use the processor, and the extent to which each processor uses. Some processes, you can easily read because they are directly linked to a program that you run at that time, such as iexplore.exe (Internet Explorer) WINWORD.exe (Microsoft Word) or taskmgr.exe (Task Manager).
Most, however,not be so obvious. For example, you will see multiple entries for svchost.exe in the list and, therefore, occupies a large part of your processing power. One wonders if this program is really necessary and what impact the end of the process will have on your system. (In fact svchost.exe part of the Windows operating system that handles processes executed from DLLs, and it is very important for stability and security of your computer's performance.)
All requests to the list:necessary. When you install programs on the computer where the program is usually installed in your Startup list. Every time you boot your PC each program on this list will move to the memory of your computer if you use it or not. Of course, these programs are only wasting your system resources when not in use and could be arrested without any negative impact on the operation of your computer.
From time to time, despite the latest firewall or moreUpdate antivirus a malicious program finds its way to your PC. Since the process list of Task Manager is pretty cryptic, and it is not exactly practical to engage in mind all the legitimate process running on your computer, to determine the nature of each process is essential efficiency and security of the computer.
Find out what each process is and how it is important to how your computer is not so difficult task as it may seem tothe first time. You can specify the name of a process in your favorite search engine to find that this is the case, or if there are sites that can provide information about processes, such as whether friends or enemies, or if they are critical or are simply a waste of resources on your computer.
