@stefanRTR Back to winintegrator! Working great, some small adjustments: 1) though I uncheck More games option in Features they are back again then I remount lited image. This happens only with win7 ultimate version but it would take much time to find out what cuases this behaviuor. 2)Print and document services options for Ultimate are not saved in preset. Would be nice to add language removal detailed option to remove at least biggest language files: chinesse etc. Using winintegator on win7 ult with recapturing after install I get install.wim 1511mb. This is with netframework and homeroup left in. Removing just speech recognition with vlite drops wim size to 1200mb! Suggest you to add tjis feature too, but as far as I remember speech reoval was integrated into vista not as separate package, but as a part of core... Great and very clean removal, flalwless integration! Thank you! @all never had unmount error or any other errors. Very simple. Install win 7, disable netframework 3.51, install net framework 4 beta version, waik and winintegrator. Backup drive. Test! That simple! Pls let stefan to concentrate on removals, not on unmount problems! If You get dism exit code 5 while integratinf the drivers, check file properties and it will get obvious why winintegtator can not integrate it. Most commonly it will be blocked file as gotten from other pc. Cheers, Alex
