Windows 8 and later no longer asks you to confirm the deletion of files and folders, i.e when you select a file/folder and hit Delete key, it sends the respective item straight to Recycle Bin without confirming the action. Here is how to bring the delete confirmation dialog back.
Note that in XYplorer you can suppress the delete confirmation dialog, even if Windows is configured to show it, by ticking this:
Configuration | File Operations | Miscellaneous | Suppress delete confirmation dialog
However it does not work the other way round! If Windows is configured to NOT show it then XYplorer cannot be made to show it.
Note that from XYplorer 17.10 onwards you can enable a native delete confirmation prompt that is independent from the Windows prompt. See here for details.
