Open Task Manager (Ctrl-Alt-Delete), look for Applications running, then you right click the application. Go to "Go to process" you should have the application name.
EDIT: Blessed Google Image Search, searched your pic and first result was the ASUS driver page - AI Suite II / III. Seems like it is this, isn't it?
EDIT + UPDATE: Searched a little more, found this answer written by TwoCables at overclock.net. After reading it seems to be written for AI Suite II but it should work for III as well. Quoting the relevant parts:
1 - Open Task Scheduler (in Vista and 7, open the Start Menu, type task scheduler, and then press Enter)
2 - On the far left side, expand Task Scheduler Library
3 - Select "ASUS"
4 - In the middle, you'll see two Tasks named "ASUS AI Suite II Execute", and "ASUS DigiVRM Help"
5 - Right-click them and choose "Disable" (you can select both by holding down either Shift or Ctrl and left clicking them)
6 - Close Task Manager
So now AI Suite II will no longer start with Windows! The best part is
that AI Suite II will not automatically undo these changes any time
you open it, so now it's just like any other program. You can also
Shut Down or Restart while AI Suite II is running, and it will still
not cause it to start with Windows.
However, there are still a bunch of processes running in the
background! Fortunately, you can easily disable all of them and never
have to worry about it! Here's how:
1 - Open Services.msc (open the Start Menu, type services.msc, and then press Enter)
2 - Look for the following services:
- ASUS Com Service
- ASUS HM Com Service
- ASUS System Control Service
3 - Change both "ASUS Com Service" and "ASUS HM Com Service" to Manual.
4 - Change "ASUS System Control Service" to Disabed.
So now when you open AI Suite II, it will still be able to start both
"ASUS Com Service" and "ASUS HM Com Service" (both of these start up a
few other processes at the same time). I mean, if these were set to
Disabled, then you'd get an error.
Note: every single process that gets started by these two services
will continue running even after completely exiting AI Suite II.
Fortunately, they do not automatically start with Windows! So if you
wanted to be in complete control and always stop them right after
exiting AI Suite II, then go into Services.msc, right-click the two
services we set to "manual", and then choose "Stop". Although, you'll
have to remember to do this every single time if you are a person like
me who likes to keep everything under control. hehe
