As the topic title indicates, I'm getting an explorer.exe spike every 10-20 seconds causing short delays in most of my applications. I've followed several performance procedures, chkdsk, defragmentation, etc. as well as ran virus scanners and spyware tools, but I haven't found the root of the problem yet. When I ran process explorer it shows the CPU being used by an SHLWAPI.dll!Ordinal505+0x37a thread. Here are the logs requested in the posting procedures.

Looking at the processes, I noticed that lsass.exe was writing continuously to the hard drive, this may also be the problem. I validated that it was in the correct location to ensure it wasn't some copy of the executable.

I was able to disable terminal services using the following steps:

To disable terminal service:

1. Run 'regedit'. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Terminal Server
TSEnabled = 0

2. Control Panel --> Administrative Tools --> Services: Terminal Server = manual

3. Run 'regedit'. HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Win dows\Installer
"EnableAdminTSRemote"=dword:00000000

4. Reboot and check the services, it should be on manual and not started.

This resolved the lsass.exe writing to the IO, but unfortunately the explorer.exe is still spiking every 10-20 seconds. I'm lost. According to procmon, it's doing some kind of TCP/IP orriented tasks. Any help would be greatly appreciated.
