# When I click on the approve or reject buttons in an approval email, why does my browser open?
Approval emails leverage **"mailto" links** embedded within the **Approve** and **Reject** buttons. Depending on your computer’s configuration, your browser may be set as the default application used to handle these links. Below are steps to adjust this setting in [**Windows 10**](#windows-10) and [**Windows 11**](#windows-11).
### Windows 10
1. Search your computer for **“Default apps.”**
2. On the **Default apps** screen, choose your preferred mail client as the default **Email** app.
### Windows 11
1. Search your computer for **“Default apps.”**
2. In **Set a default for a file or link type**, search for **“mailto.”**
3. Click to change the default to your preferred mail client.
Please contact your **IT department** for additional assistance with your company’s specific system configurations.
