Hi all, I would like to report back on my project of XP x64: I have finished customizing XP after a week of working day and night, XP now feature a modern visual style, improved logon UI, custom msgina.dll, shell32.dll etc, loads of drivers and updates (IE8, MP11 and post SP2 updates) XP is now running perfectly and very fast (much faster than XP x86) on my acer Aspire 7740G laptop. Even hibernation is very fast with 5GB RAM. It is a pleasure to work on my laptop now. If anyone would like the customized visual style for x86 and x64 it is available at no cost. Jennifer
