Surface Asset Tag is a command line interface (CLI) utility that allows you to view, assign, and modify an assigned asset tag value for Surface devices.

System requirements

  • Surface Pro 3 or later and all newer Surface devices
  • Unified Extensible Firmware Interface (UEFI) firmware version 3.9.150.0 or later.

Using Surface Asset Tag

To run Surface Asset Tag:

  1. Download the Surface IT Toolkit and install it on the PC you use to manage devices in your organization.

  2. Open Surface IT Toolkit. Select Tool Library > Surface Asset Tag > Save a copy and choose ARM64 or X64.

  3. Open a command console as an Administrator and run AssetTag.exe, entering the full path to the tool.

  4. Restart Surface.

    Note

    After setting the asset tag, a second reboot is required before it appears in WMI.

Asset Tag tool commands

In the following examples, AssetTag.exe is saved in a directory on a local machine (C:\assets).

To get the proposed asset tag, run AssetTag -g:

C:\assets\AssetTag.exe -g

To clear the proposed asset tag, run AssetTag -s:

C:\assets\AssetTag.exe -s

To set the proposed asset tag, run AssetTag -s testassettag12:

C:\assets\AssetTag.exe -s testassettag12

Tip

The asset tag value must contain between 1 and 36 characters. Valid characters include A-Z, a-z, 0-9, period (.) and hyphen (-).

Managing asset tags

You can view the existing asset tag in the UEFI settings under Device Information (Control Panel > Recovery > Advanced Startup > Restart now.)

The following figure shows the results of running the Asset Tag Tool on Surface Go.

Alternately, you can use WMI to query the existing asset tag on a device:

(Get-WmiObject -query "Select * from Win32_SystemEnclosure")

Example

C:\Windows\System32> (Get-WmiObject -query "Select * from Win32_SystemEnclosure")

Using PowerShell

You can use the following script as a way of getting the proposed value and interpreting any errors.

AssetTag -g \> $asset\_tag 2\> $error\_message  
$asset\_tag\_return\_code = $LASTEXITCODE  
$asset\_tag = $asset\_tag.Trim("\`r\`n")

if ($asset\_tag\_return\_code -eq 0) {  
Write-Output ("Good Tag = " + $asset\_tag)  
} else {  
Write-Output (  
"Failure: Code = " + $asset\_tag\_return\_code +  
"Tag = " + $asset\_tag +  
"Message = " + $error\_message)

}
