On some Windows 7 systems when you right click on "Computer" in the start menu and then click "Manage" you would get an error, or "Manage" wouldn't open at all.

This little reg tweak will fix it and have "Manage" From the right click menu working again :-)

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}\shell\Manage\command]
@=hex(2):6d,00,6d,00,63,00,2e,00,65,00,78,00,65,00,20,00,63,00,6f,00,6d,00,70,\
00,6d,00,67,00,6d,00,74,00,2e,00,6d,00,73,00,63,00,00,00
 

Enjoy!
