Software Deployment

I might be totally off the base, but in my experience, .pnf files are generated by the system. I do normally keep .inf files whenever those are captured - there's sometimes useful info inside those.

Usually when you see OEM*.INF files popping up in %SYSTEMROOT%\INF, it means that Windows has installed a driver. When Windows installs a driver (always from an INF file somewhere), it copies the file to %SYSTEMROOT%\INF and gives it a new OEM based name. The PNF files are generated automatically and are basically precompiled versions of the INF files (I think).

I would say that the driver should either be separated from the software installation, or dealt with in the correct way for drivers (use the DIFX driver installation framework).

Does oemxx.inf and oemxx.pnf pairs gets created for only signed drivers while installing the driver using dpinst.exe at runtime or for un-signed drivers also they get created?

can anyone provide some info on this?

have a look at this very good info from v jay READ

you can also do a search for dpinst / difxapp

lots of info on this forum
