What is the name of the new icon that appears on your desktop? If it put an item on your desktop, it may have just downloaded the update, and not installed it.
Keep in mind, according to Microsoft's article, you do have to edit the Registry to enable the Hotfix. If you have not edited the Registry following the instructions Microsoft has provided, the Hotfix likely will not work.
As always, Back up the Registry before doing any editing, and be careful. Making incorrect changes to the registry can prevent your computer from starting properly, and is done at your own risk.
