...when logged into a Server via remote Desktop?
I see no way to Access Windows security. In "old" 2008 R2 there was a "Windows Security" entry in the start menu when coming via rdp.
In the new Metro Start Menu, the username context menu allows me to lock the Computer or log out - but not Change the Password.
Yes, I can go through user Management, but this is not something I want People to do ;)
