win-export-drivers
In Windows, drivers are usually stored in the following directories:
C:\Windows\System32\Drivers
C:\Windows\System32\DriverStore
C:\Windows\System32\DRVSTORE
(not always present)
You can copy them on a USB stick pendrive, then insert it into another PC and install the drivers there, by selecting the pendrive location when Windows asks for a directory to "find the drivers automatically".
