If you want a totally customized Windows XP, then renaming the Recycle Bin can be quite useful. You could rename it to trash, garbage [or pretty much anything you can imagine ].
Follow these steps to rename the Recycle Bin:

2. Locate HKEY_CLASSES_ROOT/CLSID/{645FF040-5081-101B-9F08-00AA002F954E}
3. Change the registry value “Recycle Bin” To anything. (Remember to exclude the quotes!)
And you’re done!
