<p>I have just installed Windows 8 in dual boot mode on my laptop. During Windows 8 Enterprise Edition installation I had no prompt to enter the product key.</p>
<p>Upon successful installation I was noted that I have to activate my Windows, but unlike Windows 7, I couldn&#8217;t find an option to change the product key.</p>
<p>Therefore I asked my good friend from Microsoft and I got the following answer.</p>

<p><span style="text-decoration: underline;">Solution 1</span> (courtesy: <strong>tshepo</strong>)</p>
<p>Run the following command in Run prompt:</p>
<p><strong>slui 3</strong></p>
<p>The activation page will appear where you can type your new key. Activation should be automatic upon entering the new key.</p>
<p><span style="text-decoration: underline;">Solution 2</span></p>
<p>Open <strong>CMD</strong> in elevated mode (run as administrator)</p>
<p>Type the following command:</p>
<p><strong>slmgr.vbs -ipk PRODUCT KEY</strong></p>
<p>Replace the <strong>PRODUCT KEY</strong> with your valid Windows 8 Enterprise key.</p>
<p>After successful message product key will be changed and Windows 8 will be automatically activated.</p>
