Kernel Mode Drivers Manager is an interesting tool which can tell you much more about the drivers running on your PC.
Simply run the program on any 32 or 64-bit version of Windows (2000/ XP/ Vista/ 7/ Server 2003 and 2008 are supported) for the full list of loaded drivers. This includes the file path and name, publisher, description and load order, most usefully, although the driver's base address and image size are also available if you need them.
Looking for malware? Kernel Mode Drivers Manager can highlight suspect files, though slightly bizarrely this isn't turned on by default. Right-click within the list, select "Highlight Suspicious Modules", and if the program thinks a driver is dubious for whatever reason then it'll be highlighted in red. (This isn't exactly reliable, though, so don't start trying to delete files just because they are highlighted here, or you could make your situation very much worse.)
The program can also hide Microsoft drivers with another right-click option. That can be handy when you're troubleshooting as you'll then see only drivers associated with applications you've installed.
If you spot a driver you don't recognise, then right-click it, select Search on Google > Filename, and a browser window should open with more information.
And Kernel Mode Drivers Manager can even copy some or all of your drivers to a folder somewhere, which may be useful if you need to analyse them in some other way (or perhaps just want to back them up).
This isn't the type of program you'll need often, but when you'd like to find out more about your system's drivers then Kernel Mode Drivers Manager is a good place to start looking.
