Answer 3

There is a possibility that you have the following Registry setting configured:

HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\System!DisableCMD

If you see the value ' DisableCMD ' in the above location then simply delete it.

If you are not comfortable with editing the Registry then you will find this setting by going to:

Start > RUN

Type gpedit.msc and press OK

Navigate to: User Configuration > Administrative Templates > System Look for the option ' Prevent access to the command prompt ' Double click it and choose ' Not Configured '
