-compatible with the latest version of Emacs.

+@env{SHELL}, @env{TERM}, @env{HOME}, @env{LANG}, and

+or the @file{HKEY_LOCAL_MACHINE} section of the system registry, under
+the @file{/Software/GNU/Emacs} key. When Emacs starts, as well as
+checking the environment, it also checks the system registry for those
+variables.
To determine the value of those variables, Emacs goes through the
-following procedure. First, the environment is checked. If the
-variable is not found there, Emacs looks for registry keys by that
-name under @file{/Software/GNU/Emacs}; first in the

there, in the @file{HKEY_LOCAL_MACHINE} section. Finally, if Emacs
-still cannot determine the values, compiled-in defaults are used.
+still cannot determine the values, it uses the compiled-in defaults.
+
+Note that the registry settings have global system-wide effect: they
+will affect all Emacs sessions run on the system. Thus, if you run
+different Emacs versions, or use both installed and un-installed Emacs
+executables, or build newer versions of Emacs, the settings in the
+registry will cause all of them to use the same directories, which is
+probably not what you want. For this reason, @emph{we recommend
+against setting these variables in the registry}. If you have such
+settings in the registry, we recommend that you remove them.
+
+If you run the Emacs MS-Windows installation program
+@command{addpm.exe}, it will update any existing registry settings of
+the @env{emacs_dir}, @env{EMACSLOADPATH}, @env{EMACSDATA},
+@env{EMACSPATH}, @env{EMACSDOC}, @env{SHELL}, and @env{TERM} variables
+to have the values suitable for the installed Emacs version with which
+@command{addpm.exe} came. Note that @command{addpm.exe} will
+@emph{not} create any registry setting that didn't exist, it will only
+update existing settings, which are most probably inherited from an
+old Emacs installation, so that they are compatible with the newly
+installed Emacs version. Running @command{addpm.exe} is no longer
+necessary when installing recent versions of Emacs, so we only
+recommend doing that if you are upgrading from an older version, and
+cannot remove these settings from the registry for some reason.
In addition to the environment variables above, you can also add
