This page provides Windows registry information for the official Windows Tailscale client.
|
|
|
|
|
<p>
|
|
|
|
|
<p>
|
|
|
|
|
The registry file will configure Tailscale to use <code>{{.URL}}</code> as its control server.
|
|
|
|
|
<p>
|
|
|
|
|
<h3>Caution</h3>
|
|
|
|
|
<p>You should always download and inspect the registry file before installing it:</p>
|
|
|
|
|
<pre><code>curl {{.URL}}/windows/tailscale.reg</code></pre>
|
|
|
|
|
|
|
|
|
|
<h2>Installation</h2>
|
|
|
|
|
<p>Headscale can be set to the default server by running the registry file:</p>

</ol>
|
|
|
|
|
<p>Or</p>
