Such a goal arises quite often, because some system commands are not executed without Windows Administrator rights. Why in Seven and Eight admin is not entirely the admin, and often not the admin at all, I note in the next article devoted to the issue of enabling a fully-fledged administrator account. Also there, in one of the methods, it is necessary to run the command prompt window as administrator. Since for Windows 7 and 8/8.1 this goal is achieved in different ways, I'm separately giving a sequence of actions for different versions as well as screenshots, which are as always clickable.

Windows 7.

1. Click the Start button or press the Windows key.
2. At the command prompt type: cmd.
3. In the results list find cmd.exe and right-click on it.
4. In the popped up menu select Run as administrator.

Windows 8/8.1

1. Open the Start menu. To do this, press and hold down the Windows, and then press X (Win+X). In Windows 8.1 the Start button returned to the desktop, so you can open the same menu by right-clicking on it.
2. In the opened menu select Command Prompt (Admin).

In conclusion, I would add that, looking at the title of the command prompt window you can easily determine whether it is open with admin rights or without them. In the first case, the title will be Administrator: Command Prompt, in the second case - just Command Prompt.
