command linewindows 8
When I access the Run dialog in Windows 8 and type cmd, it opens a command prompt but it doesn't have administrative privileges.
Looking for cmd at the default start screen does show a command prompt shortcut but it is not admin either.
Is there a way of opening an admin command prompt or it is not possible anymore?
To answer the first part of your question, when you hit the Windows key and type "CMD" you can hit Ctrl + Shift + Enter to open as administrator.
To answer the second part of your question, paste the following into notepad and save it with a ".reg" extension:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Directory\shell\runas]
@="Open Command Window Here as Administrator"
[HKEY_CLASSES_ROOT\Directory\shell\runas\command]
@="cmd.exe /s /k pushd \"%V\""
Then run the file. It will merge the changes into the registry and add the option to your context menus. (No shift key needed.)
Press 
+ X then press A to open a CMD.exe with admin rights.

Yes, it is possible and there are several ways of doing it:
Right click in the bottom left corner of the screen to open that menu too, and then click on "Command Prompt (Admin)".
Launching it from the start screen is also possible, and there are 2 ways that I know of:
3.1. Holding down Ctrl+Shift before clicking it (or any other program for the matter) will open it with admin privileges (thanks to ernie for the info).
3.2. Holding down Ctrl alone or right clicking the shortcut will show a bottom menu with options, one of which is "Run as administrator":
Anyway as Misha says you should really consider if you need an administrator terminal.
