System Information
Operating system: OS 10.14.6 (18G8022)
Graphics card:

Blender Version
Broken: Version 2.92.0 (2.92.0 2021-02-25)
Worked:

I am not a programmer and I hope not presenting something due to my ignorance, but:

Short description of error
Duplicating an object there is no way to avoid mirroring changes to the other object.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

I have tried to work on edit>Prederences>Editing>Duplicate Data, working and setting differently all properties in that menu, but no way, working in edit mode on a mesh changes automatically same details on the duplicate.

Hope is note due to my ignorance and that is effectively a bug, best regards.

Are you duplicating with {key Alt D}?
Please also always share an example .blend file where this happens.

Yes i duplicated using hot key Alt+D.
I attach .blend file.
Duplication.blend
Preferences where set as per picture, but also modifying them (including Mesh tickbox unticked) the mirroring between the 2 objects in edit mode was continuous.

{key Alt D} will always create a linked duplicate [sharing the same mesh data], so editing one object will propagate to all other linked duplicates.
This is expected behavior.

The preferences you are showing are for "regular" duplication.

So if you use "regular" duplication ({key Shift D}) and have the checkbox for Mesh ticked in preferences (should be the default), then you should end up with independent meshes which can be altered independently.

Does this work for you?
