Is there any possibility to avoid this frame using the "Opciones" selection?
You cannot supress that message.
It is put there deliberately to remind you that making changes to the Registry can cause big problems and can break, or even brick, your machine.
Some days ago, this frame did not appeared. But later, it appeared each time that corrected any file in the "Register".
It always appears when you click on the blue 'Review selected issues' after scanning.
The only time that it would not appear is if you only did a 'Scan' but then nothing else.
If there were no issues found by the scan, or if you had unticked everything found then the 'Review selected issues' button would be greyed out.
