I'm trying to make my own customized Windows XP install CD. I use WINDOWS XP x64 (for work) and WINDOWS XP x86 for gaming. Is it possible to implement these improvements on next version of nLite ? Windows x64 and x86 - integrate a MUI Language package. As you know, Windows XP x64 is only in English language. I'm from Spain, and i want to make my own spanish CD (x64) and galician CD (x86 and x64). Is it possible to integrate them like if they were a Service pack or a Critical Upgrade ? I saw several pages that explains hot to make a different language CD with the 0C0A.MSI and _MUIINST.BAT and editting WINNT.SIF . but i think this method sucks, and it waste a lot of disk space (0C0A.MSI is 181Mb long, and i have to use a DVD) and when i re-edit the installation folder with nLite, it looses the WINNT.SIF text line that call _MUIINST.BAT. - Integrate dotNetFx 2.0 and 3.0 - Messenger Live! (like if they were a Critical Upgrade and not an AddOn) or just replacing the old one it comes with WINDOWS XP. Being an addon, i can't cutomize to be Spanish, because the addOn is in English lang... - Customize names in more folders when XP is already installed (like COMMON FILES, DESKTOP, CONTACTS, MY DOCUMENTS and much others) to translate them into spanish/galician as if they were the DEFAULT names like it happens in WINDOWS XP x86 CD (in that SPANISH CD they're translated) Windows x64 only - Slipstreaming WMP11 . Not possible in x64 (yes in x86) What do you think ? Any other usefull implementation that people may think it's interesting? Just write your ideas ! Thankyou very much ...and excuse me if my english is not perfect, but as you have read, i'm from Spain...
