If you have Windows 7 Beta installed with UAC disabled you might run into problems while trying to load gadgets onto your desktop.You can enable the UAC in order to use Sidebar.But if you don't wanna turn on that nagging UAC and still love those tiny useful gadgets you can bring them aboard by following these steps:

* Click on Start button, type regedit in the search box and hit enter.
* In regedit, go to :

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Sidebar\Settings

* In the right pane,right-click and select DWORD Value from the New menu.
* Rename the DWORD Value to AllowElevatedProcess. Double-click on it and type 1 in the Value data field.




* Close Registry Editor and try to load the gadgets.They should work.

Thanks Chris for finding the registry

Thanks Dishant!
