USP (menu) - How to configure System management?

Question

right now my System Management section has:
Root Terminal (totally not useful)
Control Center (not that useful either)
Lock Screen (don't need it)
I want to add things like Quit, Logout, Shutdown, Install software...
How do I do that? I know there are people using it

Answer 1

I don't see creation is indicated in the log. It attempted to created it then is says "System Management could not be created". It's one of those interesting things really. Why even try creating it? Interesting... ConfigMgr servers should not have access(create)
to "System" container at all.
It is clearly defined here as how to create it 
http://technet.microsoft.com/en-us/library/bb633169.aspx. Use AD Users and computers, it's simpler
Click Start, click Run, and then enter
dsa.msc to open the Active Directory Users and Computers administrative tool.
Click View, and then click Advanced Features.
Expand the System container.
Right-click System Management, and then click Properties.
In the System Management Properties dialog box, click the
Security tab.
Click Add to add the site server computer account and grant the account
Full Control permissions.
Click Advanced, select the site server’s computer account, and then click
Edit.
In the Apply onto list, select This object and all child objects.
Click OK.
