We’re currently testing a ML Windows 8.1 build – 30+ languages, so languages are injected on demand, based upon network location. One thing we ran into was that the Modrn App tiles were still in the base OS language (en-US).
This appears to be a known bug as outlined here: http://support.microsoft.com/kb/2928948/en-us
The solution? Simply add a Run Command Line task to your Task Sequence after “Setup Windows and Configuration Manager” stage to execute the following command:
{code lang:text showtitle:false lines:false hidden:false}Schtasks.exe /change /disable /tn “\Microsoft\Windows\AppxDeploymentClient\Pre-staged app cleanup”{/code}
