Page file is easy. Once you set your you can export out the reg key.
For me, my default is a 2048 mb file on the C drive. This is for normal systems for my customers. They should never need bigger than 2GB. If they are using over 2GB of the page file, which runs off the hard drive, then they have some real problems.
Here is the reg info for the file
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]
"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,00,73,00,79,00,73,00,20,00,32,00,30,00,34,00,38,00,20,00,32,00,\
30,00,34,00,38,00,00,00,00,00
You can change yours on your system then simply export that key out, and there you go.
