====== How to Fix Missing NULL Driver in Windows Fundamentals ======

Windows Fundamentals, or WinFLP, is a tiny old system well-usable on old machines. However, it is lacking NULL driver, which will probably cause many command-line installers to fail. This is how to fix it quickly.


===== Adding NULL driver to Windows =====

This is a re-phrased, polished and updated walkthrough from original source [[http://taoofmac.com/space/com/Microsoft/Windows/FLP|here]].

  - Download null.sys driver and required registry settings from {{:blog:odborny:winflp_null_driver.zip|here}}.
  - Copy ''null.sys'' to ''c:\windows\system32\drivers\null.sys''.
  - Run ''regedit'' and go to ''HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\Root''.
  - Right-click on the ''Root'' folder, choose ''Permissions…'' and add the ''Administrator'' user with full control.
  - Right-click on the ''Root'' folder again and create a new key under it called ''LEGACY_NULL''.
  - Run ''null.reg'' unpacked from downloaded zip file.
  - Reboot.
  - Go to ''Device Manager'', select ''View -> Show hidden devices'' and find ''Null'' under ''Non-Plug and Play Drivers''.
  - Under ''Driver'' tab, change ''Current status'' to ''Started'' and select ''Boot'' as a ''Startup type''.
  - Done!


===== Checking if NULL driver is present and working =====

  - Open ''cmd''.
  - Write ''echo >nul''.
  - If no error is displayed, NULL driver is working well, otherwise you will see ''The system cannot find the file specified.'' error.
