Hi Ruch, this is not a Windows dll file, so there must be some software on your startup looking to load that file . . .
Press Ctrl + Shift + Esc to open Task Manager
Click on the Startup Tab
Check for any non-essential software listed there
If it is, select it and click 'Disable'
Close Task Manager
Click your Start Button, type msconfig and hit Enter
When the System Configuration dialog opens, click on the Services Tab
Check the box marked 'Hide Microsoft Services'
In the remaining list check for any non-essential software listed there, uncheck any you find
Click Apply and OK
Restart your System and this annoyance will be gone . . .
