Win7 system CMD command can not be called how to do

I do not know why, open the computer run dialog box, after entering the CMD command, I thought that you can run the relevant program through the command at the command prompt, after the completion of the CMD command, the "ld" command The prompt has been disabled by the system administrator ”. It may be because the function was turned off when the rainforest woodwind win7 Ultimate feature was set, so it was disabled. What method can we use to lift this restriction? The operation steps are as follows:
First, use the Win+R key combination on the keyboard to quickly call the running window, then enter the gpedit.msc command in the running program, then press and hold back This command can be executed by the car key.
Second, as shown in the following figure, open the win7 pure version system to download the local group policy editor, we can see the menu items in the left column, expand in the menu on the left, "user configuration" & rdquo;-&ldquo "Administrative template", "-“ system", and then in the open system file, you can see that there is a "set access command prompt" in the list of settings menu on the right.
Third, right click on the mouse, select the "Edit" item in the pop-up menu of win7 Ultimate. Change the setting “Enabled”edit to “disabled" or “unconfigured”, then click the bottom app and OK button to take effect.
At this point you can run the C MD command by running the dialog box. In the open command prompt, you can type the command, that is, the command prompt no longer prompts the disabled prompt.
