First you need to download all the needed updates and hotfixes. 1.Update Rollup 2 for Windows XP Media Center Edition 2005 (KB900325) http://www.microsoft.com/downloads/details...&DisplayLang=en 2.Update Rollup 2 for eHome Infrared Receiver for Windows XP Media Center Edition 2005 (KB912024) http://www.microsoft.com/downloads/details...&DisplayLang=en 3.Update for Windows XP Media Center Edition 2005 (KB913800) http://www.microsoft.com/downloads/details...&DisplayLang=en 4.April 2006 Update Rollup for Windows XP Media Center Edition 2005 (KB914548) http://www.microsoft.com/downloads/details...&DisplayLang=en Then you need to extract WindowsXPMediaCenter2005-KB900325-usa.exe (or the one in your own language) inside is a folder called "bin" Delete everything inside exept the hotfixes. Copy these to your $OEM$ folder exept "KB900325.exe" (we need that one later) Files to place in $OEM$ : wmfdist95.exe WindowsMedia10-KB895572-x86.exe WindowsXP-KB891593-x86.exe WindowsXP-KB895961-x86.exe WindowsXP-KB899337-v2-x86.exe WindowsXP-KB899510-x86.exe WindowsXP-KB888795-x86.exe WindowsXP-KB902841-x86.exe Now open your CMDLINES.TXT and add the following lines : "wmfdist95.exe /Q:A /R:N /C:"wmsetsdk.exe /WMFDIST /Q /R:N /DisallowSystemRestore"" "WindowsMedia10-KB895572-x86.exe /quiet /norestart" "WindowsXP-KB891593-x86.exe /quiet /norestart" "WindowsXP-KB895961-x86.exe /quiet /norestart" "WindowsXP-KB899337-v2-x86.exe /quiet /norestart" "WindowsXP-KB899510-x86.exe /quiet /norestart" "WindowsXP-KB888795-x86.exe /quiet /norestart" "WindowsXP-KB902841-x86.exe /quiet /norestart" Now make a new folder in the folder where you put your software. For example , this is how mine looks like : D:\xpcd\SOFTWARE So with the new folder it looks like this : D:\xpcd2006\SOFTWARE\mceupdates ( i called the new folder "mceupdates" ) Put all the other hotfixes inside that folder. KB900325.exe WindowsXPMediaCenter2005-KB914548-ENU.exe WindowsXP-KB912024-v2-x86-ENU.exe WindowsMedia10-KB913800-x86-ENU.exe (Make sure you downloaded them in your own language) I use RunOnce to install my software , so i can only tell you how i install them.** REG ADD %KEY%\017 /VE /D "MCE2005 Updates" /f REG ADD %KEY%\017 /V 1 /D "%CDROM%\Software\mceupdates\KB900325.exe /quiet /norestart" /f REG ADD %KEY%\017 /V 2 /D "%CDROM%\Software\mceupdates\WindowsMedia10-KB913800-x86-NLD.exe /quiet /norestart" /f REG ADD %KEY%\017 /V 3 /D "%CDROM%\Software\mceupdates\WindowsXP-KB912024-v2-x86-NLD.exe /quiet /norestart" /f REG ADD %KEY%\017 /V 4 /D "%CDROM%\Software\mceupdates\WindowsXPMediaCenter2005-KB914548-NLD.exe /quiet /norestart" /f (Ofcourse you need to modify it to make it fit in your cd) **NOTE Make sure before the hotfixes get installed .net 1.1 is already installed. All this will make the loading time when you enter windows for the first time after install a bit longer. But thats normal, and is only the first time. I hope i cleared things up a bit now.
