Thanks a lot for your reply, the key bath is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory ManagementWhen I set it manually to custome size to be 1024 MB as initial size and 1500 MB as Maximum size... I right click the value PagingFile and found it read C:\pagefile.sys 336 672 D:\pagefile.sys 1024 1500and when I export it to .reg file I found it read Windows Registry Editor Version 5.00 "PagingFiles"=hex(7):43,00,3a,00,5c,00,70,00,61,00,67,00,65,00,66,00,69,00,6c,\ 00,65,00,2e,00,73,00,79,00,73,00,20,00,33,00,33,00,36,00,20,00,36,00,37,00,\ 32,00,00,00,48,00,3a,00,5c,00,70,00,61,00,67,00,65,00,66,00,69,00,6c,00,65,\ 00,2e,00,73,00,79,00,73,00,20,00,31,00,30,00,32,00,34,00,20,00,31,00,35,00,\ 30,00,30,00,00,00,00,00So now I will integrate the .reg file only directly during unattended setup, right?
