Yes, yet another oldie with a secret…<\/p>\n\n\n\n

The .inf files are as old as Windows itself, and their internal structure has been covered by many, and over at least last two decades.<\/p>\n\n\n\n

So, what’s new?<\/p>\n\n\n\n

Well…<\/p>\n\n\n\n

Ever heard of LoadAdvpackExtension<\/em> ?<\/p>\n\n\n\n

This simple .inf file demonstrates how to use it to load a DLL of your choice:<\/p>\n\n\n\n

\n

[version]
signature=”$CHICAGO$”
AdvancedINF=2.5,”test”<\/p>\n\n\n\n

[DefaultInstall]
Patching=1
LoadAdvpackExtension=test64.dll<\/p>\n<\/blockquote>\n\n\n\n

To launch it, you need to do the following:<\/p>\n\n\n\n

Place the above .inf file in c:\\test\\test.inf
Place test64.dll in c:\\test
Go to terminal: cmd.exe
Run: set path=.
Run: c:\\windows\\system32\\rundll32.exe advpack.dll,LaunchINFSection c:\\test\\test.inf,,1,<\/pre>\n\n\n\n
We change the PATH to make sure our test64.dll is found in a current directory, and then loaded:<\/p>\n\n\n\n
