Fix 100% CPU Load svchost.exe (Windows XP SP3)

Fixing the memory leak in WinXP SP3 SVCHOST.EXE 100% CPU Usage by system start.

SVCHOST.EXE (see in Process Explorer) Freeze 3 to 7 Minutes - no system response by:

- Internet Connect Dial in
- Connection Software Medion Verbindungsassistent (Huawei Webstick Connection Manager) / Join Air 1&1 (ZTE Internet Surf Stick)
- ADSL DLink Router/Modem,...
- and others...

Generic Host Process for Win32 Services C:\WINDOWS\system32\svchost.exe (5.1.2600.5512) Since service Pack 3 may freeze for several minutes by system or internet application start.

How I fixed it:

Remove from SVCHOST Network Service DnsCache

Start, Run, type in Regedit:
Go to:
SOFTWARE\Microsoft\Windows NT\CurrentVersion\SvcHost
Deleting the Value "NetworkService = DnsCache"



If you have several times reconnect on different USB Ports Websticks, you may disconnect the usb devices and clean/delete all redundant USB Entries of the same devices with USBDeview from Nirsoft.net

Uninstall the software for Surfstick/Webstick


Install the latest Drivers/Software after connecting the actual Surfstick.

Result: computer start within seconds again and internet is immediately ready to connect, which took more than 5 minutes before.

Hi there. I have a problem and I am not sure if that method is really the right fix. Please help me out. Here's the problem.

Generic Host Process for Win32 Services has encountered a problem and needs to close. We are sorry for the inconvenience.

Then there are options to do: Debug ; Send Error Report ; Don't Send.

When I click Debug what happens next is the screen goes back to Windows Classic (the taskbar turns gray).

When I click Don't Send the screen freezes, nothing happens.

When I click Send Error Report after a few minutes another message will appear. The message is like this:

svchost-1620: svchost.exe - Application Error

The instruction at "0x7c922235" referenced memory at "0x00000000". The memory could not be "read".

By the way here's the Error Signature.

szAppName: svchost.exe szAppVer: 5.1.2600.5512 szModName: ntdll.dll szModVer: 5.1.2600.6055 offset: 00022235

I am using Windows XP Professional Version 2002 Service Pack 3.

Please help me, I am not really good with technical stuff. Please..

Thank you..
