The Windows Explorer window, up as it is on my other display and completely out of mind, would still be in focus and receive the Ctrl+Z hotkey, reversing a file operation I may have done hours ago.
If I do something in the Windows Explorer window, look back at the code editor window, and decide to undo an edit to the code, I might press Ctrl+Z without remembering to put the code editor window in focus first. a code editor arranged on multiple displays. This is, of course, intended behaviour, but the way I work I'm always looking back and forth between open instances of Windows Explorer and e.g. If you press Ctrl+Z while Windows Explorer is in focus (this includes the taskbar and desktop), you will Undo the last file operation such as a delete, rename, move, or copy. I recently started using Windows again after some months of using Ubuntu exclusively, and I decided to fix something that had always bugged me about its built in file browser, Windows Explorer.
Most versions of Windows (tested in 7 and 8.1)
