McAffe suite? humm..
by jose_luis2006 - 4/25/09 12:54 AM In reply to: Re: 100 percent CPU usage caused by SVCHOST process, need he by ebernersI bought a new Toshiba NB100 netbook with factory installed WinXP Home and Mc Affe (demo) suite. I did not work as it should; I had to uninstall the McAffe SW because it was freezing the computer too often and for too long periods.
I installed Norman AV instead and everything is fine since then.
Norton?

If I recall, I had issues with that particular process on an XP machine. It was related to Norton Anti-Virus or some other Norton software. Stopped using Norton and solved it.
Possible Solution on 100 Percent CPU Utilization
by gwiljr - 4/19/09 6:39 PM In reply to: 100 percent CPU usage caused by SVCHOST process, need help by Lee Koo (ADMIN)
In my case, the problem was due to a service associated with a multifunction HP print device (HPSLPSVC). After installing the printer via its associated CD, it took what seemed like an eternity for my computer to boot and reach a point where I could intermittently use the mouse and keyboard. Applications took way to long to initiate. CTRL+ALT+DELETE would take some time to take effect. Something was seriously wrong.
This problem greatly frustrated me. Neither Microsoft nor HP (the manufacturer of my machine, and most of my peripherals) were of any help. Each kept pointing the finger to the other. HP would blame Microsoft (due to SVCHOST), and Microsoft blamed HP (due to HPSLPSVC). My conclusion was that HP was at fault since SVCHOST is a "wrapper" around services and functions fine for most. The problem had something to do with the HP service and either how it was designed or how it was initiated under SVCHOST.
Window's Task Manager was of little help. It did not provide the level of detail I needed to figure out the problem at first. Ultimately, the utility Process Explorer helped me drill down into my system to find the item consuming so much of my CPU's time. Here is a link to the lastest version as of my writing.
http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx
After starting Process Explorer, I ordered the list of items by CPU usage. This allowed me to find the specific SVCHOST bundle that appeared to be consuming so much of my CPU. I then expanded the view to show everything within the SVCHOST package. With the CPU column still displayed, it was here that I found a service called HPSLPSVC utilizing so much of the CPU. After displaying the Command Line column, I then traced the service back to a program, HPQTRA08.EXE, which I disabled using MSCONFIG. After rebooting, I again had use of my computer.
By the way, I had to kill the service in order to interact with my computer. The situation got so bad, the system would not even shut down until I killed the CPU hog.
I tried to do a little research on the problematic service. I found references to the service performing scan for HP devices through hard connections (e.g. USB and router) and soft connections (wireless). One article indicated the default frequency needed to be decreased (through a registry modification). I never pursued testing these items.
I found several other articles during my research about the same symptoms involving other multifunction devices as well as scanners. I suspect the issue may be in how the software for these devices are designed to scan for signals (like a keypress). For me, I was able to disable the problematic programs in favor of initiating a scan from with an application interacted with the device via a better managed driver.
I hope this information will help you in your efforts to drill down to the specific program within a SVCHOST bundle causing your problems.

Thank you for your descriptions and information. In my case it started happening after installing a Vodafone 3G PCMCIA card and software. Many emails to and from MS, Vodafone etc yeilded no solution. Eventually I reformatted the whole system and am currently busy with a rebuild! If the problem comes back I will be using your information to try to solve it.
Processes eating up CPU cycles/time.
by jfordorl - 4/25/09 9:09 AM In reply to: Possible Solution on 100 Percent CPU Utilization by 7sinewave32From all I read here and from my own experience this is almost always related to files or programs which want to auto update all the time. It seems that the more files that want to auto update you have on your computer, the worse it is. What I have done is to use msconfig startup panel to turn off most auto updates from starting up at turn on and afterward, and choose to manually update every month or two or three depending of frequency of actual updates available.
BTW, on a related topic, in England they recommend two things: keep your programs on one hard drive (or partition) and your data on another. Then reinstall your operating system and reinstall your programs (the ones you really want to keep) every two to three years. That way your system is cleansed of the junk and installed/uninstalled junk programs you downloaded and really don't use or need. I did it and my boot time cut in half and things like DVD creation cut in less than half!
Solution to your HP problem
by TheBigOldDog - 4/25/09 2:33 AM In reply to: Possible Solution on 100 Percent CPU Utilization by gwiljrI have seen that HP problem at least a half dozen times om systems running XP. Try this. It's worked every time so far:
Start->Run->services.msc
search for service "HP Network Devices Support" . Service name is HPSLPSVC Edit this service and set to "manual". Reboot. That should solve the problem and does not affect Printer functionality at all.
As you know, this is a known issue that has yet to be addressed to my knowledge by HP. This solution can be found on the HP user forums.
svchost 100 percent cpu
by flasher404 - 4/25/09 8:55 PM In reply to: Possible Solution on 100 Percent CPU Utilization by gwiljrNote: This reply is associated with WinXP, not Vista
I had a similar problem with HPSLPSVC which is part of the HP Multi-function printer programming; however only on one of my machines. It turns out the it is somehow connected to Intel CPU's with hyperthreading. A dual core one does not seem to have the problem and neither does an older Pentium without hyperthreading. Just recently I had a similar problem with Skype on this same hyperthreading system. It went full bore on the cpu (not svchost in this case). I don't know whether it is a problem with the cpu but I seem to have isolated it to this type of cpu. Things work fine on my other systems.
One thing that helps is what was in another post. Run services.msc and change the HP network devices support startup to 'Manual' instead of automatic.
Which generation of of CPU are you using?

I've had the same issue when turning the computer on. When it first came on the computer would be at 100% CPU usage for about 30 minutes. I had just installed Vista 32 bit on a Pentium 4 3.0(Northwood 512k cache) on a Asus 865 motherboard and 1 gig of memory. Tried everything listed here to but to no avail. The only thing that worked is when I upgraded to a dual core computer with 2 gigs of memory. My suggestion is to 1) Upgrade your PC or 2) Downgrade your OS to Windows XP until Window 7 comes out.

I had the same problem with my windowas vista, it put so much strain on my pc that my CPU ran twice the heat than on windows XP. i dont know how but the problem was corrected wen i loaded the new Tuneup Ytillities 2009 and i haven't had a problem since. a word of advice for all vista users, use tuneup utils for better OS usage.
Similar Problem
by OmoEko - 4/20/09 2:14 AM In reply to: 100 percent CPU usage caused by SVCHOST process, need help by Lee Koo (ADMIN)
Sorry Lee Koo, I do not have an answer for you but also suffer from a similar problem. Every time I log on to an alternative LAN (home or office) i get a message syaing that 'Host Process for Windows Services stopped working and was close. A problem caused the application to stop working correctly. Windows will notify you if a solution is available.' The problem is that there are many of these SVCHost that run and it is not possible to know which has been stopped and why. Can anyone help. I use a Sony Vaio VGN-SZ460N and Sony has not been able to resolve.
Legitimate Microsoft Windows File name is SVCHOST.EXE

SVHOST.EXE is a Trojan.
What you have is a virus program running on your
computer. Update your software or use a different
vendor to remove the infected file.
SCVHOST.EXE
by shelial - 4/20/09 4:33 AM In reply to: 100 percent CPU usage caused by SVCHOST process, need help by Lee Koo (ADMIN)
Let me add to that question. I am running XP Pro.
I have svchost.exe running EIGHT times in my processes. 3 times as SYSTEM, 3 times as LOCAL HOST and twice as NETWORK SERVICE.
What the **** is all this?
Shelia
2 different spellings there.
by DADSGETNDOWN - 4/20/09 10:01 AM In reply to: SCVHOST.EXE by shelialYour subject title says "SCVHOST.EXE".
Which is a problem, Unless you misspelled it, it is a trojan or some other thing.
But what you wrote in your actual message ALL 8 of those "svchost.exe " are more than liekly legit applications,
Your internet connection, windows or some other firewall, antivirus programs, spyware programs abd thinbgs like that.
BUT to be sure therre is a program or 2 mentioned somewhere in this thread that you can use top find out what exactly those are controlling.
Process Explorer one of the programs that was mentioned it does not even have to be actually installed as a program on your computer it will run right from the folder you use it from. and I believe can be downloaded right from here at Cnet, go to the downloads section of Cnets Download.com
