Windows XP: svchost.exe
svchost.exe
by mosamasharaf - 9/24/04 4:29 AMMy hard disk is active (green light is blinking) all the time even if there are NO program is opened. Opening the Win Task Manager - Processes shows that:
Image Name: svchost.exe
User Name: SYSTEM
CPU: 20% to 84%
Mem Usage 9,139K
My operating System is Win XP Pro
Hard Drive 20GB, Processor 1GB Pentium 3
My Q. is: Why this file (svchost.exe) is active all the time & taking all the memory ? How can I stop that?
Thank you,

I recently had such a pest invade my machine.
Try running scans with Ad-aware and Spybot Search & Destroy. I delete all that they find, and have not had any problems. They are free and you can download them here: http://www.pcworld.com
Let us know what you find.
Good Luck.

1. The article [Q310419] describes issues concerning computer speed and decreased performance caused by programs loaded at startup, programs that create memory leaks, and the situation when a computer has a small or minimal amount of random access memory (RAM), or a slower central processing unit (CPU).
2. The article [Q822430] explains that when you click a large Audio Video Interleaved (AVI) file in Explorer, Windows may stop responding (hang), you notice that the Explorer.exe process consumes 100 percent of CPU usage for up to two hours or more, and occurs when Windows tries to query the index of the file, which isn't there and then attemps to build one. Read the TweakXP tip "AVI files causing high cpu usage again with installation of XP SP1" to prevent Explorer from loading shmedia.dll in response to their file property queries causing 100% cpu usage.
3. The article [Q314056] describes Svchost.exe (%SystemRoot%\System32 folder), the generic host process name for services that run from dynamic-link libraries (DLLs), can run in multiple instances at the same time, and each session can contain a grouping of services so they can run depending on how and where it is started. Please note, the built-in "Task Scheduler" -- a "huge word that" (Schedsvc.dll) component is made up of the MSTask.exe service file and a user interface (UI) component in MSTask.dll that you can use through Windows Explorer or through Control Panel and is hosted by the file Svchost.exe in the Netsvcs group.
Note: If you feel a service stared and running is to blamed for the excessive CPU usage, use the procedure in [Q811267] to stop services one at a time simply for the purpose of determining which one could be causing the anomaly.
4. The Power Options Tool (Powercfg.exe) is a utility which was introduced in Windows XP Service Pack 1 (SP1) that can be accessed from this tool in Control Panel to set certain power options. Whether they will be of use or help is anybody's guess, [Q324347].
5. When a Microsoft Foundation Classes (MFC) application is run on WinXP, a memory leaks for Graphics Device Interface (GDI) objects may be seen when creating and destroying child windows and can be observed in the GDI objects of the process in Task Manager. This can occur when a program make many calls to the StgCreateDocFile function to create compound storage objects and causes a 512-byte memory leak to occur - an error, STG_E_FILEALREADYEXISTS (0x80030050). To resolve problems of this type when applicable, "Obtain the Latest Windows XP Service Pack" described in [Q319740].
6. The article [Q309073] states that by sending a particular set of commands to an affected system, an attacker could gradually deplete resources on the system to the point where performance could be slowed or stopped altogether. The vulnerability results because the Universal Plug and Play (UPnP) service that either ships with or can be installed does not correctly handle certain requests and can cause a memory leak.
7. The article [Q315000] states that unchecked buffer in Universal Plug and Play can lead to System Compromise and describes two vulnerabilities that affect the implementation of UPnP in various products. Although the vulnerabilities are unrelated, both involve how UPnP-capable computers process the discovery of new devices on the network. To resolve this problem obtain the latest sevice pack for Windows XP.
8. Laptop users may experience this problem if the power policy changes because of an AC/DC transition while the computer is using the "Max Battery" power scheme. When the computer is running at 100 percent CPU usage, the computer never enters the idle loop in which the speed of the CPU is dynamically adjusted based on demand and current policy values. The supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in, [Q330512].
9. Open Task Manager and click the Processes tab to see a list of "running processes" (click to see a screen shot) - click the CPU column header to sort the list of processes by their CPU utilization as desired.
a. You may find that if the Microsoft Indexing Service (Cidaemon.exe) is used and cause the high CPU utilization.
b. In Task Manager, you can right-click an active program or process and change the amount of CPU power it gets until it's closed, which then reverts back to the XP's default assignment -- Low, BelowNormal, Normal, AboveNormal, High and Realtime.
10. While on the subject of CPU usage and how to tell -- or should I say "attempt to tell", I wonder if Microsoft really fixed things for XP. Referencing an older published article [Q227131], it explains that the System Monitor tool may display incorrect CPU Usage that can occur for any of the following reasons, and which you can safely ignore since it is not indicative of a problem:
CPU usage rises to somewhere between 20-60 percent even though you are not running any programs.
CPU usage declines sharply when you move your mouse.
CPU usage declines sharply either when you run Windows Media Player or play a .wav file.
CPU usage rises when you dial-up to connect.
CPU usage does not fall from 100 percent.
Note: In addition, the older article [Q178563] states that if you use System Monitor to monitor more than one occurrence of "Kernel: Processor Usage," the second and following occurrences of "Kernel: Processor Usage" show 100 percent processor usage. As a workaround to this behavior, use only one occurrence of "Kernel: Processor Usage" in System Monitor, or use two separate occurrences of System Monitor.
11. Supplemental reading: "A Program Stops Performing a Task or Explorer.exe Uses 100% of the CPU When You Right-Click an Item in Windows Explorer (Q819946)."
