Hi. I have Windows 7 All Version x86 i x64 on my private once DVD. Size is 3,55 GB. I integrated all updates to January 2011. I used DISM with bat file: @echo off title .:: UPDATES ::. start /wait c:\Windows\system32\DISM.exe /image:d:\dismtool\wim /add-package /packagepath:d:\dismtool\updates After this ISO have... 4,77 GB and is too big for DVD. I have questions: Why after integration size is bigger? Old files should be overwritten by new and size should be comparable. What now?
