Svchost.exe is using 100% cpu Slowing everything down i have tryed everything using system restore and completly nuking my computer is nearly impossible due to the lack of cd drive.

Glad to help YOU!

The svchost.exe file is located in the folder C:\Windows\System32.
On STARTUP Svchost.exe checks the services portion of the registry and constructs a list of services that it needs to load. Usually multiple instances of Svchost.exe will be running simultaneously. If the process svchost.exe uses high CPU resources it is mostly due because Windows Operating System is downloading some updates.
WARNING: A 100% CPU usage could lead to the presumption of a hidden malware on your computer!!! Same for the message that you got: "scvhost.exe driver not ready"...
I'd suggest you to do a SPYWARE/MALWARE scan AS SOON AS POSSIBLE and AS DEEP AS POSSIBLE!!!


GOOD LUCK!

Here is my resolution to the error
SVCHOST.EXE GENERIC HOST PROCESS OR
DEP ERROR

IT DOES NOT INCLUDE
DISABLING WIA
OR
DISABLING DEP (which is a good security feature)


I have tried it on upto 3-4 computers with success and complete software functionality
*******************************************
Turn the All in One Off
Uninstall the whole of the HP software on the computer
Run a level 4 uninstall

Start --> Run -->X:\Util\CCC\Uninstall L4.bat

Restart the computer
*******************************************
Check the computer on the restart
Check if you still get an SVCHOST.EXE GENERIC HOST PROCESS OR
DEP ERROR on restart


Start --> Run
Type in Msconfig
Click OK
Click Launch System Restore
Run System Restore
Create a Restore Point named Hp

Click Start --> Run
Type in Regedit
Click OK
Open Registry Editor
Scroll to the following Registry Key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentV
ersion\Explorer\

Right click on this Key Click Export
On the Export Registry Window which comes up
Type Hpprinter as the filename and save it on the desktop

Get back to the same Registry Key
Right Click the Key and Click Delete to remove the key


Restart the computer
THERE SHOULD BE NO DEP ERRORS THIS TIME

(IF you have any issues after deleting the above key <possibility is remote> restore the computer back to the Hp restore point)

*******************************************

Reinstall the Hp printer Wirelessly or on a wired network now the usual way


Once the software installation finishes
Verify functionality

*******************************************
NOW
Right-Click My Computer, then click Properties.

On the Advanced tab, under Performance, click Settings.

On the Data Execution Prevention tab

Click Turn on DEP for all programs and services except those I select to select the OptOut policy, and then click Add to add the following programs

Create an exception in the DEP for the following programs by browsing to the correct location. The following list outlines the locations:


Hpcmpmgr.exe (x:\Program Files\HP\Hpcoretech\hpcmpmgr.exe)

HPwuSchd2.exe (x:\Program Files\HP\HP Software Update\hpwuSchd2.exe)

HP Digital Imaging Monitor (hpqtra08.exe) (x:\Program Files\HP\Digital Imaging\bin\hpqtra08.exe)

HP Image Zone Fast Start (hpqthb08.exe) (x:\Program Files\HP\Digital Imaging\bin\hpqthb08.exe)

Generic Host Process for Win32(svchost.exe)
(c:\windows\system32\svchost.exe)

Add all these files one by one by browsing to the locations

Click Apply and OK
Let the computer restart if prompted
******************************************

Its also at times needed to disable
from the Startup of the computer in Msconfig

Hpcmpmgr.exe
HPwuSchd2.exe
HP Digital Imaging Monitor (hpqtra08.exe)
HP Image Zone Fast Start (hpqthb08.exe)

The reason is the above mentioned exceptions to the Data Execution Prevention are loaded after the Startup loads and the DEP may try to shut them down at the startup itself and generate the errors
Unchecking the above files does not mean losing any functionality on the All in One all the features should work properly

SVCHOST.exe is NOT a virus, however, it sounds like you do have a virus. SVCHOST is the program that operates your 'snap-ins' or 'services'. Services like .net runtime, DHCP client, DNS client, Messenger, netmeeting, Universal PNP and so forth. These services are part of embedded system modules and are the very heart of Windows 2K and higher, and the SVCHOST is the program that manages and operates them. If your SVCHOST is eating your resources, then its likely a corrupted service, (infected program launched by the host) or a fake service, starting and grinding the pc to a halt. in either case, your BEST option is to prepare to reformat your machine. Get your self a USB flash drive, launch in safe mode, and move your documents and data over to the drive as best as you can, then gather your system restore disks and wipe and reload your system. And once you do that, go straight to your antivirus manufacturers website and get the latest edition installed. Personally, I use AVAST HOME FREE Edition.

Svchost.exe acts as a host for a group of services on your computer. As you are aware there a many services and programs the run silently in the back ground. Svchost.exe pools many of these services in one group and runs all at the same time. This is a great for efficiency. However, it can cause your CPU to spike to 100%.

As mentioned before svchost.exe is essential. So the trick is not to block svchost.exe, its to limit your computers need to use it. You can limit your computer need for svchost.exe. By cutting down on the services that are loaded when you PC starts. This can be done quite easily.

1. Open your Start menu.
2. Click Run
3. In the command screen type: msconfig
4. In the "system configuration utility", Click "services" tab
5. Uncheck all services that are unnecessary.
6. Click "OK"
Uncheck the suspecious services but make sure you do not stop necessary services. Restart the PC to take them affect

To complete part one, follow these steps:

1. Insert the Windows XP startup disk into the floppy disk drive, or insert the Windows XP CD-ROM into the CD-ROM drive, and then restart the computer.
   Click to select any options that are required to start the computer from the CD-ROM drive if you are prompted to do so.
2. When the "Welcome to Setup" screen appears, press R to start the Recovery Console.
3. If you have a dual-boot or multiple-boot computer, select the installation that you want to access from the Recovery Console.
4. When you are prompted to do so, type the Administrator password. If the administrator password is blank, just press ENTER.
5. At the Recovery Console command prompt, type the following lines, pressing ENTER after you type each line: md tmp
   copy c:\windows\system32\config\system c:\windows\tmp\system.bak
   copy c:\windows\system32\config\software c:\windows\tmp\software.bak
   copy c:\windows\system32\config\sam c:\windows\tmp\sam.bak

In software Svchost.exe is a generic host process name for services that run from dynamic-link libraries (DLLs) within the Microsoft Windows operating system.
At startup, Svchost.exe checks the services part of the registry to construct a list of services that it must load. Multiple instances of Svchost.exe can run at the same time. Each Svchost.exe session can contain a grouping of services. Therefore, separate services can run, depending on how and where Svchost.exe is started. This grouping of services permits better control and easier debugging, but it also causes some difficulty for end users wishing to see the memory usage or vendor legitimacy of individual services and processes. End users in Windows XP Professional (and derivatives, such as Windows Server 2003 and Windows XP Media Center Edition) can run the following command at the system prompt to get a breakdown:
tasklist /svc /fi "imagename eq svchost.exe" (NB: This command does not work in Windows XP Home.)
Due to being widespread among running processes, svchost.exe has long been a common disguise used by malware to hide its presence from the user. (One of the common trojan horses deceptively uses scvhost.exe). Users may then run tasklist with no arguments and match the reported PIDs with the previously shown Svchost instances. If memory usage appears abnormal, the user can look up the service names shown by their command on the internet to see if it is a known service or malware.
The Svchost.exe file is located in the %SystemRoot%\System32 folder. The main registry key involved at bootup is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SvcHost (values in this key will show the user at least a partial list of the actual processes behind instances of svchost).
The 30 April, 2007 release of WSUS 3.0 led to reports of svchost.exe issues, including 100% CPU usage, memory hogging, and excessive laptop fan/power usage.[1]

"Svchost.exe" (Generic Host Process for Win32 Services) is an integral part of Windows OS. It cannot be stopped or restarted manually. It manages 32-bit DLLs and other services. At startup, Svchost.exe checks the services portion of the registry to construct a list of services that it needs to load. In normal conditions multiple instances of Svchost.exe run at the same time. Each Svchost.exe session can contain a grouping of services, so that separate services can be run depending on how and where Svchost.exe is started. This allows for better control and debugging. The svchost.exe file is located in the folder C:\Windows\System32. In other cases, svchost.exe is a virus, spyware, trojan or worm! To detect if it's a virus sometimes it will add letters to the Svchost to read thus SSVCHOST or SVCCHOST or something like that, thus making multiple services to run and slow down the computer, if that is the case the current antivirus you are using is not removing the virus, this can be done in the registry, its a complicated process if you do not know how to do it, so i would suggest you purchase a registry cleaner. NOTE: remember to backup the registry before you clean it

u can change antivirus i suggest u can install norton antivirus 2007

this is an all too common problem with windows services host, but you will have to refer to this site as there are a few things you can try http://ask-leo.com/svchost_and_svchostexe_crashs_cpu_maximization_viruses_exploits_and_more.html
