<div class="content wysiwyg-content">
I have an existing KMS host, working just fine. &nbsp;I want to add an upgraded KMS host key so this host can activate windows 8, 8.1 and server 2012. &nbsp;The KMS host is running Server 2008 R2. &nbsp;I have installed the required updates that allow Server 2008 based KMS hosts to activate 8.1 clients along with server 2012 clients.<br />
<br />
My question is this: &nbsp;When I add the new key using slmgr /ipk &lt;KMS Host Key&gt; will that cause my clients to go into the black screen mode that says windows is not genuine when they check in every 7 days, while the KMS host waits for the minimum 25 activation attempts?
