    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Sysprep\Specialize

  2. Change the value {EC9FE15D-99DD-4FB9-90D5-676C338DC1DA} to the following, for all three registry keys:

    • reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Sysprep\Cleanup /v {EC9FE15D-99DD-4FB9-90D5-5B56E42A0F80} /t REG_SZ /d "C:\Windows\System32\iesysprep.dll,Sysprep_Cleanup_IE" /f
