Would you believe it? Checked for updates (Win 7) and lo and behold KB3035583 had un-hidden it self again.?

So I hid it again.

Also, after I installed the latest updates (except KB3035583) a homegroup icon had appeared on my desktop.

Sooooo, I removed that by going to :-

Control Panel

Network & Internet

Appearance and personalisation

Personalisation

Change desktop icons

In the Desktop Icons box, checked the network box, then unchecked it, clicked apply, clicked OK.

The icon was gone.
