Modify delete dialog to always focus "No"-Button by standard

I know this hasn't much to do with the taskbar, but it's Explorer related.

I want to suggest an option, which modifies the delete dialog of files/folders to focus the "No"-button by standard.

The reason is safety, so that it's not that easy to confirm the deletion with the standard focus on "Yes".

I did search the web already, modified serveral registry values, but it doesn't seem to be possible to modify the Windows Explorer dialogs in other ways.

Once, I deleted a 20GB folder accidently. Could only recover about 15 GB.

The only solution I have found so far is to turn off the delete key by modifying the key codes.
