+value of @code{HOME}.
+
+  You can override this default value of @code{HOME} by explicitly
+setting the environment variable @env{HOME} to point to any directory
+on your system.  @env{HOME} can be set either from the command shell
+prompt or from the @samp{My Computer}s @samp{Properties} dialog.

-When Emacs starts, it first checks whether the environment variable
-@env{HOME} is set.  If it is, it looks for the init file in the
-directory pointed by @env{HOME}.  If @env{HOME} is not defined, Emacs
-checks for an existing @file{.emacs} file in @file{C:\}, the root
-directory of drive @file{C:}@footnote{
-The check in @file{C:\} is for compatibility with older versions of Emacs,
-which didn't check the application data directory.
-}.  If there's no such file in @file{C:\}, Emacs next uses the Windows
-system calls to find out the exact location of your application data
-directory.  If that system call fails, Emacs falls back to @file{C:\}.

-  Whatever the final place is, Emacs sets the value of the @env{HOME}
-environment variable to point to it, and it will use that location for
-other files and directories it normally creates in the user's home
-directory.

+Older versions of Emacs didn't check the application data directory.
+}, if there is a file named @file{.emacs} in @file{C:\}, the root
+directory of drive @file{C:}, and @env{HOME} is set neither in the
+environment nor in the Registry, Emacs will treat @file{C:\} as the
+default @code{HOME} location, and will not look in the application
+data directory, even if it exists.  Note that only @file{.emacs} is
+looked for in @file{C:\}; the older name @file{_emacs} (see below) is
+not.  This use of @file{C:\.emacs} to define @code{HOME} is
+deprecated.

   You can always find out where Emacs thinks is your home directory's
 location by typing @kbd{C-x d ~/ @key{RET}}.  This should present the
 list of files in the home directory, and show its full name on the
 first line.  Likewise, to visit your init file, type @kbd{C-x C-f

+	* ebuff-menu.el (electric-buffer-menu-mode-map): Move initialization
+	into declaration.  Remove redundant and harmful binding.
+

+	* files.el (file-ownership-preserved-p): Pass `integer' as an
+	explicit 2nd argument to `file-attributes'.  If the file's owner
+	is the Administrators group on Windows, and the current user is
+	Administrator, consider that a match.
+
+	* server.el (server-ensure-safe-dir): Consider server directory
+	safe on MS-Windows if its owner is the Administrators group while
+	the current Emacs user is Administrator.  Use `=' to compare
+	numerical UIDs, since they could be integers or floats.
