I had to edit the registry to get rid of that pesky thing on my EEEPC

Disable Unwanted Startup Programs
Click Start and then Run. Type regedit and press Enter. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Run. Click on the Run folder and notice all of the programs that start up when your Eee starts up. Most of these were installed by installing the drivers from ASUS. You can delete as many of these as you want and your Eee will still start up just fine.
Here's an explanation as to what all of them do, so you can decide if you want to keep them or not.
(Default) - Default folder key. Don't delete this.
Alcmtr - Application that installs with the audio driver. Delete it.
AsusACPIServer - This is the ACPI driver for your Eee. You can safely delete this and the Windows ACPI driver will do a fine job of controlling fan speed with CPU temp.
AsusTray - This utility is used to switch between 800x480 and 800x600. If you don't use this, you can delete it to speed up Windows boot time.
HotKeyCmds - You can safely delete this and your Fn+[Key] commands will still work fine.
IgfxTray - Intel tray icon. Delete it.
Persistence - More intel junk. Delete it.
RTHDCPL - Installs with the audio driver. Delete it.
SkyTel - I think this is part of the modem, which is integrated with the audio chipset. Delete it.
