How get Admin credentials? I am the Admin already <p>My new computer have Windows 8.1 64-bit Spanish version; the previous one had Windows XP and I never messed before with Credentials, Privileges, etc. In my computer there is just one user account that is marked as Administrator: "They have access to all files and programs stored in the computer". However, if I open a command-line window and execute <code>chkdsk</code> I get this:</p> <pre><code>Microsoft Windows [Versión 6.2.9200] (c) 2012 Microsoft Corporation. Todos los derechos reservados. C:\Users\Antonio&gt; chkdsk Acceso denegado porque no tiene privilegios suficientes. Invoque esta utilidad ejecutándola en modo elevado. </code></pre> <p>That is: "Access denied because you have not enough privileges. Invoke this utility executing it in elevated mode". I tried to use <code>runas</code> command, but I don't understand what parameters I must give.</p> <p>I get the same result when I execute <code>fsutil</code> with these options:</p> <pre><code>C:\Users\Antonio&gt; fsutil fsinfo ntfsInfo C: Error: Acceso denegado. </code></pre> <p>How can I execute these programs in my computer? TIA</p>
