  • If your INF file has a newer version and date the OS will replace the old driver with a new one.  If you are doing testing this is a good reason to use .kdfiles in the debugger since you can have Windbg update the driver from your development environment to the test system automatically.

  • I have two version drivers. Which has passed WHQL, they have theri digital signature.

    I want to develop a dirver setup. I don't know how to do when I update the driver(Maybe from old version to new, or from new version to old).

    When I update the driver, should I uninstall the current driver? Or just use any API to do this?

  • Well the assumption is you update from old to new.  What you can do is use the DIFX tools either the tool or the API.  If you use these for the install program they include the ability to completely uninstall a driver, which means you could go back to the older version.
