I only have one i suppose you can cancelled 4 of them but leave one on.

Stay out of task manager unless you need to end a non-responsive program. If you need to ask a question such as this, you are already over your head. Computers are finicky bastages and don't take lightly to people messing around.

In the Task Manager, you will find (most) every program which is currently running on your computer. If you have several IE windows open on your computer at the same time, this will also reflect in the Task Manager as well. Closing them should end those programs as seen in the Task Manager. You can go online and google "Task manager Programs", or even just the individual tasks you see listed in the Task Manager. You can then see what each task listed in the window is supposed to be doing and determine whether or not you need it running. For example, if you aren't currently using RealPlayer and you have RealPlayer processes running, you can shut them down and this shouldn't adversely affect your computer. In fact, it should free up some processing capabilities for your other programs to use. If you indiscriminately shut down processes without knowing what they do, you may end up doing something which may keep your computer from functioning properly, or shutdown something you really DIDN'T want to shut down. This is irritating, but NOT fatal. Simply restarting your computer, as a worse case scenario, will fix your mistake. This is because when you shut down those processes, you aren't DELETING anything, nor are you changing any settings. You simply told the computer to stop that program. When you restart your computer, it will still go through everyting it needs to do in order to start up and operate. If you are having performance problems, use Task Manager to see WHAT is eating up all your processing capabilities to see what you need to look at. Then google these processes to see what they are for and whether or not you can just shut them down. Also, you can see if anything which you KNOW is needed (like IE, if you use IE to browse) is using excessive amounts of processing power. I once had a problem with IE shuttind down on me, but I could restart it and work fine for a while before it did it again. Looking in Task Manager, I could see that IE was requiring more and more processing power the longer it stayed open. I eventually looked at all the IE add-ons I had active and started shutting down unnecessary ones until that stopped happening. Here are a couple links I googled up on the tasks you listed: http://www.howtogeek.com/howto/windows-vista/what-is-svchostexe-and-why-is-it-running/ http://www.neuber.com/taskmanager/process/iexplore.exe.html

If you have 5 internet explorer windows open, then all five need to be there. However, if not, you might want to get IE7. I had internet explorer 8 and sometimes it would spawn like 50 iexplore.exe processes randomly and wouldn't let you end them. It was a pain so I went back to 7.

The iexplorer.exe are separate internet explorer processes and unless you've five separate windows open crashed or hidden screens which should be closed, use a better browser. SVChost is a system process but also a disguise for a lot of malware. Ideally you just want three and the rest on manual as it saves on RAM and increases system speed. do a services.msc in the run box on startup and then look at the services running and see if you really do need them.

I stopped using IE at IE6, but the SCVHOST thing is probably normal. But use Firefox or Google Chrome instead of IE. Either saves some headaches. http://www.mozilla.org http://www.google.com/chrome
