# Setting an Asset Tag in the Virtual Machine BIOS

Asset tags help identify, control, and track computer assets in an organization. Parallels Desktop for Mac Business Edition provides the ability to set an asset tag in the virtual machine BIOS, which can then be read using the standard tools of the guest operating system. You can set an asset tag using the Parallels Desktop graphical user interface or the **prlctl** command line utility that comes with Parallels Desktop.

To set an asset tag using the Parallels Desktop GUI:

1. On the Parallels Desktop menu bar, select **Actions** > **Configure** to open the virtual machine configuration dialog.
2. Select **Business**.
3. Use the **Asset tag** field to specify the desired tag.

To set an asset tag using the **prlctl** command line utility, use the following syntax:

<pre><code><strong>prlctl set ID|name --asset-id tag
</strong></code></pre>

where `ID|name` is the virtual machine ID or name, and `tag` is the asset tag to set.

To obtain the asset tag in Windows, use the WMIC.exe command:

```
WMIC SystemEnclosure get SMBIOSAssetTag
```

For the complete syntax of the WMIC utility please see the Microsoft documentation.

Once set, the asset tag never changes. Even if you perform such virtual machine operations as cloning, template manipulation, registering, or any other, the asset tag always stays the same. If you do want to change an existing asset tag for any reason, you can do it manually using of the methods described above.
