Identify SVCHOST.EXE in Windows Task List

NXJeff — Thu, 12 Mar 2009 16:06:36 +0000

Last day, i've received a desktop with a windows problem that windows disconnect his internet connection automatically by displaying this message, "General Host Process for Win32 Services has encountered a problem and needs to close. We are sorry for the inconvenience. " from a customer. Usually, as what technicians do , we will just ask him to let us reformat his computer. But i realized that it wasn't just happened to him, but also to me sometime. I was experienced that "svchost.exe" error which made my all current connections disconnected and unable to control it unless I reboot my computer. So.. I spended some times on the net to find out the solution. Finally I found that "Svchost" is stands for "Service Host". Many of components of the windows system are implemented as what are called "services", programs that run in the background, those services are stand-alone executables. Since DLL cannot run on its own, svchost is the one loads DLL. Problem with svchost.exe nowadays is very common disguise used by malware to hide its presence from the user. As the task manager below does not show up much information in it. You wouldn't even know which one is being controlled or used by malware.

Why do we Defrag the Hard disk? Vopt 9.08

NXJeff — Fri, 06 Feb 2009 04:33:02 +0000

What is Defragging? Defragging is process done to a hard disk in order to improve performance and recover some lost disk space. Defragging is an essential part of a PC's upkeep as it keeps all the data on your hard disk in an easily readable order. If a hard disk is left without defragging, then over time the disk will begin to lose performance and also slowly reduce the available capacity to data. As you will be aware if your hard disk is running slowly then this will affect the rest of the system performance, in all applications and especially in games, where frame rate is important.
