Hi, though Microsoft has released the trimmed down version of their "Windows Embedded Standard 7" OS called "Windows Thin PC" but they have also locked down the option to add or remove packages or feature. So i have started this thread to share info on how to add or remove packages to the "Thin PC" OS. Requirements : 1. Windows Embedded Standard 7 SP1 Toolkit or Windows Embedded Standard 7 SP1 Runtime (IBW) x86 DVD. It can be a retail or the evaluation DVD. You can get the evaluation DVD iso image from microsoft. I think the Windows Embedded Standard 7 SP1 Runtime (IBW) x86 DVD is enough. 2. Windows Thin PC DVD. Package Path Information : The Feature Packages are stored in the \DS\Packages\FeaturePack folder of Windows Embedded Standard 7 SP1 ToolKit / Windows Embedded Standard 7 SP1 Runtime (IBW) x86 DVD. The Non-English Language Packages are stored in the \DS\Packages\LanguagePack folder of Windows Embedded Standard 7 SP1 ToolKit or Windows Embedded Standard 7 SP1 IBW DVD. The English Language Package is stored in the \LangPacks\en-US folder of Thin PC DVD. I will start with the following packages which are working properly: 1. Premium Codecs for Windows Media Player : These Codecs include - Microsoft AC3 Encoder (Dolby), Microsoft DTV-DVD Audio Decoder (MPEG-2, AAC), Microsoft DTV-DVD Video Decoder (MPEG-2, H.264), MPEG-2 Audio and Video Encoder, MPEG Layer-3 Audio Codec (MP3), MPEG-4 Decoders, Windows Media Video Codecs (VC-1).
