Force Windows 7 Update All Drivers?

I actually don't have a problem with drivers, but in how windows detects hardware and finds appropiate drivers. Because sometimes I have many computers at a time to fix, I wondered if there was a way in which windows 7 can be forced to update every installed driver in the system at once, this because when windows 7 is installed, it installs outdated (but working) drivers for some devices. Generally, I don't install drivers by double clicking them, but rather by extracting them (exe's) and then making windows find them, I do this because doing so, prevents most of the time, the installation of unwanted applications.Now, I know I can update each driver individually using the device manager, but this could take very long depending on the machine. I would like windows (on a clean installation), to uninstall ALL of the drivers, including chipset, video, audio, etc, and then look for them in a specific folder, say C:ew_drivers (where all new extracted drivers are).
