If you wish to remove an OEM driver and revert to the Microsoft driver, you must locate the appropriate %Systemroot%\Inf\OEM#.inf file, where # is a system assigned number. If you edit each %Systemroot%\Inf\OEM#.inf file, you can determine which one installs the OEM driver that you wish to remove. Once you determine the %Systemroot%\Inf\OEM#.inf file, you should move it, and its' matching %Systemroot%\Inf\OEM#.pnf file, to a different folder, in case you every want to reinstall it.
NOTE: The following oeminf.bat script may assist you in locating the correct %Systemroot%\Inf\OEM#.inf file:
@echo off setlocal cd /d "%Systemroot%\inf" for /f "Tokens=*" %%i in ('dir /b oem*.inf') do set file=%%i&call :parse endlocal goto :EOF :parse set mfg=N for /f "Tokens=*" %%j in ('type "%file%"') do set line=%%j&call :parse1 goto :EOF :parse1 if "%mfg%" EQU "Y" goto doit if "%line:~0,1%" EQU "\[" goto found goto :EOF :doit set mfg=N @echo %file% %line% goto :EOF :found if /i not "%line:~0,14%" EQU "\[Manufacturer\]" goto :EOF set mfg=YOnce you have moved the appropriate file(s), use Device Manager to right-click the device and press Uninstall. After the uninstall, restart your computer. When you log on, you should receive a New Hardware Found dialog for the device. Press Next to start the Found New Hardware Wizard. Select Search for a Suitable Driver and press Next. The standard driver should install.
NOTE: To use the OEM driver again, move the OEM#.inf and OEM#.pnf file(s) to the %Systemroot%\Inf folder, uninstall the device using Device Manager, and restart your computer.
