In Windows, if we right-click on CD/DVD drives, we get an option to "Eject" the tray but we don't get option to "Insert" the tray. In this tutorial, I'll tell you a trick to add "Insert" option in CD/DVD drives context menu.

Here is the step-by-step procedure:

1.) Download following zip file, extract it and copy the DLL file to "%windir%\System32" folder:

cdeject.zip

2.) Now download following zip file, extract it and then run the .REG file:

insert_reg.zip

That's it. Now you'll get an extra option "Insert" in CD/DVD drives context menu, which will make the life easier and you'll not have to press the insert button at your CD/DVD drive each
time.
