I now have the older version of opera and i would like to know is there any way that i can disable auto updates

To what do i rename it?

To whatever you want.

How do i call it?

It's called opera_autoupdate.exe

so if i rename it to ''opera_autoupdate disable'' it will disable the update??

Older version being....?
if you are talking about Opera 12 or older, there is an option in settings. Don't remember the path now but look in the security section.
If it's a more recent version, try renaming the auto updater executable file in Opera's installation folder.
