-2147024156 The requested operation requires elevation

Question:
I get an error "-2147024156 The requested operation requires elevation." What happens?

Answer:
This message means that the OS thinks that the gadget requests Administrator privileges for an operation and UAC blocks the request. However, the gadget does NOT do that, UAC seems to be confused or whatever.

Tip:
Try the following:

1. Turn off UAC and reboot.
   
2. Try the gadget, it should work.
   
3. Turn on UAC again and reboot.
   
4. Try the gadget again, it should work.
