Pop-up window on exit

Hi all!
I am new to the forum, just registered and I have a very weird question.

Do you know how sometimes after you installed a new software program, - you open it, work with it whatever and then on exit there is a pop-up window asking you to exit or to minimize or it may ask you something else.
Not all programs do that. Anyway on that pop-up window there is usually a box - you can put tick in it if you don't want to see that pop-up window ever again and in my case I did that.
Now who can tell me how to get this pop-up window back on exit?
I tried re-installing the program and it did not help. In fact the re-installed program somehow remembered all my settings from previous setup.
Anyone can help me with that please?

Just want to add.
The program is called Synkron. On exit it asks you to exit or to minimize. If you choose exit it will always exit completely, if you choose minimize - it will go to taskbar when you hit a cross and that's what I desperately need but I chosen exit by mistake and now I never get to see the pop-up window again. There is nothing in the options to change that. Re-installation will not help.
I know there the way to change that. Hope someone knows the answer.

Thanks!!!

Yes, there is a check box to remember the selection.
But my selection was wrong. And to change it the only way is to bring the pop-up window back.
I has to be somewhere within the program.

The thing is even if I re-install the program it does not help as all my settings come back.
I am using Revo-uninstaller to unistall the program and delete all the traces. Still no luck.
I will try to install to a different location. Maybe this will help.

Yes, I used ccleaner as well.
I will try it tomorrow on my other OS windows 8. It is clean and I will test it all carefully with ccleaner and revo.


By the way, installing to different folder does not help but installing to different disk works. But other disk still not good enough for me. I just want to get it right. It is there, it's just been locked indefinitely by my selection.
There's got to be a way to unlock the message.

I will come back tomorrow with my results.

Ok, my results are successful.
Revo plus ccleaner and most important deep search in hidden folders for any traces, delete any hidden configuration files and all as new.
