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:
HKLM (HKEY_LOCAL_MACHINE)\
SOFTWARE\Microsoft\Windows NT\CurrentVersion\SvcHost
Deleting the Value "NetworkService = DnsCache"

Reboot

===================


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

Reboot

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.
