               Emacs version 26.2 for MS-Windows

 This README file describes how to set up and run a precompiled
 distribution of the latest version of GNU Emacs for MS-Windows.  You
 can find the precompiled distribution on the ftp.gnu.org server and
 its mirrors:

      https://ftp.gnu.org/gnu/emacs/windows/

 This server contains other distributions, including the full Emacs
 source distribution, as well as older releases of Emacs for Windows.

 Information on how to compile Emacs from sources on Windows is in
 the files README and INSTALL in the nt/ sub-directory of the
 top-level Emacs directory in the source distribution, as is this
 file under the name README.W32.  If you received this file as part
 of the Emacs source distribution, and are looking for information on
 how to build Emacs on MS-Windows, please read those 2 files and not
 this one.

* Preliminaries

 There are two binary distributions named
 emacs-VER-x86_64.zip and emacs-VER-i686.zip,
 where VER is the Emacs version.  These are 64-bit and 32-bit builds,
 respectively.  If you are running a 32-bit version of MS-Windows,
 you need to install the 32-bit build; users of 64-bit Windows can
 use either build, but we recommend to install the 64-bit one, as it
 will be able to edit larger buffers and will generally run faster.

 The binary distribution has these top-level directories:

 + bin
 + libexec
 + share
 + var

* Setting up Emacs

 To install Emacs, simply unpack the binary package into a directory
 of your choice.  If you use the Windows Explorer and its "Extract"
 action, by default this will be in a top-level directory with the
 same name as the zip file.

 Emacs is completely portable.  You can create your own shortcut to
 runemacs.exe and place this wherever you find it convenient (the
 desktop and/or the Taskbar), or run it from a USB or network drive
 without copying or installing anything on the machine itself.

 It is also possible, although not recommended to use the program
 bin/addpm.exe which will place an icon for Emacs on the start page.

* Prerequisites for Windows 9X

 The 32-bit build supports MS-Windows 9X (Windows 95/98/Me).  To run
 Emacs on these versions of Windows, you will need to have the
 Microsoft Layer for Unicode (MSLU) installed.  It can be downloaded
 from the Microsoft site, and comes in a form of a single dynamic
 library called UNICOWS.DLL.  If this library is not accessible to
 Emacs on Windows 9X, it will pop up a dialog saying that it cannot
 find the UNICOWS library, and will refuse to start up.

* Starting Emacs

 To run Emacs, simply select Emacs from the Start Menu, or invoke
 runemacs.exe directly from Explorer or from a command prompt.  This
 will start Emacs in its default GUI mode, ready to use.  If you have
 never used Emacs before, you should follow the tutorial at this
 point (select Emacs Tutorial from the Help menu), since Emacs is
 quite different from ordinary Windows applications in many respects.

 If you want to use Emacs in tty or character mode within a command
 window, you can start it by typing "emacs -nw" at the command prompt.
 (Obviously, you need to ensure that the Emacs bin subdirectory is in
 your Path first, or specify the path to emacs.exe.)  The -nw
 (non-windowed) mode of operation is most useful if you have a telnet
 server on your machine, allowing you to run Emacs remotely.

* EXE files included

 Emacs comes with the following executable files in the bin directory.

 + emacs.exe - The main Emacs executable.  As this is designed to run
   as both a text-mode application (emacs -nw) and as a GUI application,
   it will pop up a command prompt window if run directly from Explorer.

 + runemacs.exe - A wrapper for running Emacs as a GUI application
   without popping up a command prompt window.  If you create a
   desktop shortcut for invoking Emacs, make it point to this
   executable, not to emacs.exe.  If you pin Emacs to the task bar,
   edit the properties of the pinned shortcut (with Shift-right mouse
   click) to point to this executable.

 + emacsclient.exe - A command-line client program that can
   communicate with a running Emacs process.  See the `Emacs Server'
   node of the Emacs manual.

 + emacsclientw.exe - A version of emacsclient that does not open
   a command-line window.

 + addpm.exe - A basic installer that adds Emacs to "Start" menus and
   adds Emacs-related entries to the Windows Registry.

 + ctags.exe, etags.exe - Tools for generating tag files.  See the
   `Tags' node of the Emacs manual.

 + ebrowse.exe - A tool for generating C++ browse information.  See the
   `Ebrowse' manual.

 Several helper programs are in a version-specific subdirectory of
 the libexec directory:

 + cmdproxy.exe - Used internally by Emacs to work around problems with
   the native shells in various versions of Windows.

 + ddeclient.exe - A tool for interacting with DDE servers.  To be
   invoked as "ddeclient SERVER [TOPIC]", where SERVER is the DDE
   server name, and sends each line of its standard input to the DDE
   server using the DdeClientTransaction API.  This program is
   supposed to be invoked via the 'call-process-region' Emacs
   primitive.

 + hexl.exe - A tool for producing hex dumps of binary files.  See the
   `Editing Binary Files' node of the Emacs manual.

 + movemail.exe - A helper application for safely moving mail from
   a mail spool or POP server to a local user mailbox.  See the
   `Movemail' node of the Emacs manual.

 + profile.exe - A helper program that generates periodic events for
   profiling Emacs Lisp code.

 + update-game-score.exe - A utility for updating the score files of
   Emacs games.

* Emacs without optional dependencies

 The files emacs-VER-x86_64.zip and emacs-VER-i686.zip contain a
 large number of optional dependencies for Emacs.

 Emacs has a number of optional features which use these additional
 dependencies.  They enable support for the following:

 - displaying inline images of many types (PNG, JPEG, GIF, TIFF, SVG)
 - SSL/TLS secure network communications (HTTPS, IMAPS, etc.)
 - HTML and XML parsing (necessary for the built-in EWW browser)
 - built-in decompression of compressed text

 If you do not want these files (if you have them already for
 instance, or you want the smallest possible Emacs), then you may use
 the files emacs-VER-x86_64-no-deps.zip or
 emacs-VER-i686-no-deps.zip. The dependency files are also available
 as emacs-MVER-x86_64-no-deps.zip and emacs-MVER-i686-deps.zip. Source
 code for these dependencies is available as
 emacs-26-deps-mingw-w64-src.zip.

 All distributions of Emacs have built in support for XBM and
 PPM/PGM/PBM images, and the libXpm library is bundled, providing XPM
 support (required for color toolbar icons and splash screen).
 Source for libXpm should be available from the same place from which
 you got this binary distribution.

* Installing Emacs with an existing MSYS2 installation

 You may also use Emacs with an existing MSYS2 installation by
 unpacking the emacs-VER-x86_64-no-deps.zip over the MSYS2
 distribution. You should not use the emacs-VER-x86_64.zip from this
 site, as this will overwrite MSYS2 files (the dependency bundle
 derives from MSYS2, but will be from a different version). You can
 then use the 'pacman' utility to install dependencies.

 Some of the optional libraries need to be of certain versions to
 work with your Emacs binary.  Make sure you install those versions
 of dependencies, and no others.  Emacs variables such as
 libpng-version and libjpeg-version tell what versions of the
 corresponding libraries are expected by Emacs.  (We recommend that
 you use the dependency bundle, where these issues are always
 resolved.)

 To install the optional libraries, start the MSYS2 Bash window and
 type the following command:

   pacman -S PACKAGES

 where PACKAGES is the list of packages you want to install.  The
 full list is as follows:

   mingw-w64-x86_64-giflib
   mingw-w64-x86_64-gnutls
   mingw-w64-x86_64-libjpeg-turbo
   mingw-w64-x86_64-libpng
   mingw-w64-x86_64-librsvg
   mingw-w64-x86_64-libtiff
   mingw-w64-x86_64-libxml2
   mingw-w64-x86_64-xpm-nox
   mingw-w64-x86_64-lcms2

 You can type any subset of this list.  When asked whether to proceed
 with installation, answer Y.

 Alternatively, you could install the packages manually from this
 page:

  https://sourceforge.net/projects/msys2/files/REPOS/MINGW/x86_64/

 However, the packages there are not self-contained, so you will need
 to manually download all their dependencies as well.

* Uninstalling Emacs

 If you should need to uninstall Emacs, simply delete all the files
 and subdirectories from the directory where it was unpacked (Emacs
 does not install or update any files in system directories or
 anywhere else).

 If you ran the addpm.exe program to create the Start menu icon, this
 can be removed by right-clicking and "Uninstall".

 Finally, addpm.exe also creates a few registry entries; these can be
 safely left, but if you really wish to remove them, all of the
 settings are written under the Software\GNU\Emacs key in
 HKEY_LOCAL_MACHINE, or if you didn't have administrator privileges
 when you installed, the same key in HKEY_CURRENT_USER.  Just delete
 the whole Software\GNU\Emacs key.

* Troubleshooting

 Some known problems and their solutions can be found in the file
 etc\PROBLEMS in the unpacked Emacs distribution.

 Virus scanners

 Some virus scanners interfere with Emacs' use of subprocesses.  If you
 are unable to use subprocesses and you use Dr. Solomon's WinGuard or
 McAfee's Vshield, turn off "Scan all files" (WinGuard) or "boot sector
 scanning" (McAfee exclusion properties).

 Windows 9X

 On Windows 9X, make sure you have the UNICOWS.DLL library either in
 the same directory where you have emacs.exe or in the directory
 where system-wide DLLs are kept.

* Further information

 The Emacs User manual describes Windows-specific issues in the
 appendix named "Emacs and Microsoft Windows/MS-DOS".  You can read
 it in Emacs by typing

       C-h r g Microsoft Windows RET

 This appendix is also available (as part of the entire manual) at

       https://www.gnu.org/software/emacs/manual/html_mono/emacs.html#Microsoft-Windows

 In addition to the manual, there is a mailing list for help with
 Emacs here:

      https://lists.gnu.org/mailman/listinfo/help-gnu-emacs

 To ask questions on this mailing list, send email to
 [email protected].

 A mailing list for issues specifically related to the MS-Windows port
 of Emacs is here:

       https://lists.gnu.org/mailman/listinfo/help-emacs-windows

 To ask questions on this mailing list, send email to
 [email protected].

* Reporting bugs

 If you encounter a bug in this port of Emacs, we would like to hear
 about it.  First check the FAQ on the web page above to see if the bug
 is already known and if there are any workarounds.  Then check whether
 the bug has something to do with code in your `.emacs' file, e.g. by
 invoking Emacs with the "-Q" option.

 If you decide that it is a bug in Emacs, use the built in bug
 reporting facility to report it (from the menu: Help -> Send Bug Report).
 If you have not yet configured Emacs for mail, then when you press
 C-c C-c to send the report, it will ask you to paste the text of the
 report into your mail client.  If the bug is related to subprocesses,
 also specify which shell you are using (e.g., include the values of
 `shell-file-name' and `explicit-shell-file-name' in your message).

 Enjoy!
