<p>In the heat of the COVID-19 crisis, Microsoft Teams, a unified communication and collaboration platform is now used more than ever. Even though this is a great app not all of the employees have the need for it. After installation, Microsoft Teams starts automatically when the user logs in and that might be a problem.</p>
<p>If Teams app is used on a shared desktop (Xenapp and XenDesktop) environments it would be useful to prevent Microsoft Teams from auto-starting to save system resources.</p>
<p>Here&#8217;s how to prevent Microsoft Teams from auto-starting using Group Policy:</p>
<p>Create a new Group Policy object and in the left pane navigate to:</p>
<p><strong>User Configuration | Preferences | Windows Settings | Registry</strong></p>
<p><img class="alignnone wp-image-3602 size-full" title="prevent Microsoft Teams from Auto-starting" src="https://www.wincert.net/wp-content/uploads/2020/03/prevent-teams-from-auto-starting-1.png" alt="" width="773" height="324" /></p>
<p>In the right pane create a new registry item for deletion.</p>
<p><strong>HKEY_Current_User\Software\Microsoft\Windows\CurrentVersion\Run</strong></p>
<p><strong>Value Name: com.squirrel.Teams.Teams</strong></p>
<p>Action: <strong>Delete</strong>.</p>

<p>Link this policy to Users container or if you need to link it to a Computer Container don&#8217;t forget to <strong>configure user Group Policy loopback processing mode</strong> at:</p>
<p><strong>Computer Configuration | Administrative Templates | System | Group Policy</strong></p>
<p>Set <strong>configure user Group Policy loopback processing mode</strong> to <strong>Merge</strong>.</p>
<p>Hope this helps!</p>
