Disabling the Windows Clipboard
When copy-pasting in Windows, sometimes the clipboard bar appears, and if you're really "lucky", it also pops up a waring, distracting you from your work. The clipboard holds only 12 items, and I have never met anyone who used more than one. There is no way to turn this irritating feature off, unless you want to use the dreaded registry editor.
