Thanks for your reply. I tried some of these tweaks yesterday and I had one only matter with this: ;----- Set custom logon box [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon] "GinaDll"="custom msgina.dll file" I had had to reboot in Safe Mode and to manually delete "GinaDll" DWORD... I believe that my experience will be useful for other international members of this forum.
