I am moving from Vista to Windows 7 Pro 64 bit. I understand that the sidebar is no longer recommended because it has security problems. However, I really like the CPU meter and slideshow gadgets.

What are my options? I can find full-screen slideshow apps, which is not what I want. I found this:
and other gadgets at this site, but I don't know if these gadgets are any more secure than the original versions, and on this slideshow gadget I don't want the clock anyway.

I have read that the original Windows gadgets can be detached from the sidebar, but I don't know if the sidebar can then be discarded, and if so if that would remove the security risk.

I do not want to use gadgets that communicate outside the computer, such as news feeds or an internet speed meter -- just mentioning in case this makes a difference.

Thank you for your help!
