Remote Server Administration Toolkit (RSAT) for Windows 8

Two important notes:

  1. Please note that the Remote Server
    Administration Tools for Windows 8 can ONLY be installed on computers that are
    running Windows 8.
  2. Remove all older versions of
    Administration Tools Pack or Remote Server Administration Tools—including
    earlier prerelease versions, and releases of the tools for different languages
    or locales—from the computer before you install Remote Server Administration
    Tools for Windows 8. Only one copy at a time of Remote Server Administration
    Tools can be installed on a computer.
