Introduction

I had this problem this morning so thought i’d post the fix, to cut a long story short when trying to Sysprep a Windows 10 build 10122 image, the sysprep process failed every time during the generalize section as revealed in the sysprep logs.

Problem

Sysprep was failing to generalize because something was stopping it from continuing the process. The errors were logged in the following folder:-

C:\Windows\System32\Sysprep\Panther

and the following files contained info pointing to the failure:-

• setupact.log
• setuperr.log

here’s a snippet from setuperr.log:-

Try stopping the Windows Installer service and ensure that no other process is accessing files inside this directory before retrying[gle=0x00000012]

Solution

It turns out that a Windows 10 service called tiledatamodelsvc is responsible, and all you have to do to fix is stop the service before running sysprep. That service prevents Sysprep from accessing the files in C:\ProgramData\Microsoft\Windows\AppRepository.

To resolve the problem, try one of these three methods:

1. Stop it with PowerShell

Stop-Service tiledatamodelsvc

2. Stop it from a cmd prompt

net stop tiledatamodelsvc

3. Stop it in the Computer Management console

Open Computer Management and select services, locate the tiledatamodelsvc, right click it, and choose Stop.

Once the service is stopped, you can sysprep the computer.
