You can disable the Keyboard Filter for Administrators.
For Windows Embedded 8.1 Industry, from a PowerShell window or script run:
Set-DisableKeyboardFilterForAdministrators $true
For Windows Embedded Standard 8, it is a little more complicated because it needs to be disabled via WMI. Microsoft does have a full script available here, but in essence you run:
$Setting =$Entry = Get-WMIObject -class WEKF_Settings @{"namespace"="root\standardcimv2\embedded"} | where { $_.Name -eq "DisableKeyboardFilterForAdministrators" } $setting.Value = "true" $setting.Put() | Out-Null
You can also change the setting in your answer file as well.
