Whinging about UAC is for wimps, this is a real Windows Vista annoyance.

1. Open Windows Explorer and navigate through the folder tree in the left pane (eg, navigate to C:Temp)

2. Drag and select one or more files or folders in the right pane that you would like to delete

3. Hit delete

Windows Vista wants to delete the Temp folder that you had last selected in the left pane, not the files or folders you just selected in the right pane.  Windows XP or Server 2003 would delete the files you had selected in the right pane.

This feature was stinging me about once a week when I first started using Vista.  Now it catches me out far less often, but it is still very annoying when it does.  Even more annoying is if you are being reckless and hit Yes (the default answer) without really reading the dialog, or are using Shift + Del to bypass the Recycle Bin, or are deleting files from a network drive (when Recycle Bin does not come into play).

Its a very annoying feature, but luckily it won’t be a problem for me any longer.
