Go to this link to get the latest win update controls
http://v4.windowsupdate.microsoft.com/cab/x86/unicode/iuctl.cab
and save them to your desktop , or better yet, save into a new unique
folder.
Extract the cab by:
1. Right clicking on the iuctl.cab
2. Select "Extract" -- point to %windir%\system32 folder and click Ok
3. Use Windows Explorer, and "right click" on the * IUCTL.INF * file.
4. Select "install". Make sure it has a clean/good finish.
5. Logout and reboot the system. This last step is important.
On XP & Win2000 the IUCTL.DLL & IUENGINE.DLL should go into
%windir%\system32.
