Windows 7 Gadgets
 

I don't know if it's just me or if its happening to anyone else, every time I reboot my PC my gadgets on the side disappear. I would have to manually put them back on. Is there a setting of some sort to keep them on when I reboot/boot my PC?

Mine turn on manually. Try going to Control Panel and playing around with Desktop Gadgets?

There's a setting under options to have it automatically start or not.
