This file documents the idiosyncrasies of the Win32 version of Vim.
The Win32 version of Vim works on Windows NT, 95, 98, ME, XP, Vista and
Windows 7. There are both console and GUI versions.
The Win32 version of Vim works on Windows XP, Vista, 7, 8 and 10. There are
both console and GUI versions.
The 32 bit version also runs on 64 bit MS-Windows systems.
There is GUI version for use in the Win32s subsystem in Windows 3.1[1]. You
can also use the 32-bit DOS version of Vim instead. See |os_msdos.txt|.

1. Known problems *windows95* *win32-problems*
There are a few known problems with running in a console on Windows 95. As
far as we know, this is the same in Windows 98 and Windows ME.
Comments from somebody working at Microsoft: "Win95 console support has always
been and will always be flaky".
1. Dead key support doesn't work.
2. Resizing the window with ":set columns=nn lines=nn" works, but executing
external commands MAY CAUSE THE SYSTEM TO HANG OR CRASH.
3. Screen updating is slow, unless you change 'columns' or 'lines' to a
non-DOS value. But then the second problem applies!
If this bothers you, use the 32 bit MS-DOS version or the Win32 GUI version.

6. Win32 mini FAQ *win32-faq*
Q. Why does the Win32 version of Vim update the screen so slowly on Windows 95?
A. The support for Win32 console mode applications is very buggy in Win95.
For some unknown reason, the screen updates very slowly when Vim is run at
one of the standard resolutions (80x25, 80x43, or 80x50) and the 16-bit DOS
version updates the screen much more quickly than the Win32 version.
However, if the screen is set to some other resolution, such as by ":set
columns=100" or ":set lines=40", screen updating becomes about as fast as
it is with the 16-bit version.
WARNING: Changing 'columns' may make Windows 95 crash while updating the
window (complaints --> Microsoft). Since this mostly works, this has not
been disabled, but be careful with changing 'columns'.
Changing the screen resolution makes updates faster, but it brings
additional problems. External commands (e.g., ":!dir") can cause Vim to
freeze when the screen is set to a non-standard resolution, particularly
when 'columns' is not equal to 80. It is not possible for Vim to reliably
set the screen resolution back to the value it had upon startup before
running external commands, so if you change the number of 'lines' or
'columns', be very, very careful. In fact, Vim will not allow you to
execute external commands when 'columns' is not equal to 80, because it is
so likely to freeze up afterwards.
None of the above applies on Windows NT. Screen updates are fast, no
matter how many 'lines' or 'columns' the window has, and external commands
do not cause Vim to freeze.
Q. So if the Win32 version updates the screen so slowly on Windows 95 and the
16-bit DOS version updates the screen quickly, why would I want to run the
Win32 version?
A. Firstly, the Win32 version isn't that slow, especially when the screen is
set to some non-standard number of 'lines' or 'columns'. Secondly, the
16-bit DOS version has some severe limitations: It can't do big changes and
it doesn't know about long file names. The Win32 version doesn't have these
limitations and it's faster overall (the same is true for the 32-bit DJGPP
DOS version of Vim). The Win32 version is smarter about handling the
screen, the mouse, and the keyboard than the DJGPP version is.
Q. And what about the 16-bit DOS version versus the Win32 version on NT?
A. There are no good reasons to run the 16-bit DOS version on NT. The Win32
version updates the screen just as fast as the 16-bit version does when
running on NT. All of the above disadvantages apply. Finally, DOS
applications can take a long time to start up and will run more slowly. On
non-Intel NT platforms, the DOS version is almost unusably slow, because it
runs on top of an 80x86 emulator.

< In the console version, you need to set the font of the console itself.
You cannot do this from within Vim.
Q. When I change the size of the console window with ':set lines=xx' or
similar, the font changes! (Win95)
A. You have the console font set to 'Auto' in Vim's (or your MS-DOS prompt's)
properties. This makes W95 guess (badly!) what font is best. Set an explicit
font instead.
Q. Why can't I paste into Vim when running Windows 95?
A. In the properties dialog box for the MS-DOS window, go to "MS-DOS
Prompt/Misc/Fast pasting" and make sure that it is NOT checked. You should
also do ":set paste" in Vim to avoid unexpected effects. |'paste'|
Q. How do I type dead keys on Windows 95, in the console version?
(A dead key is an accent key, such as acute, grave, or umlaut, that doesn't
produce a character by itself, but when followed by another key, produces
an accented character, such as a-acute, e-grave, u-umlaut, n-tilde, and so
on. Very useful for most European languages. English-language keyboard
layouts don't use dead keys, as far as we know.)
A. You don't. The console mode input routines simply do not work correctly in
Windows 95, and I have not been able to work around them. In the words
of a senior developer at Microsoft:
Win95 console support has always been and will always be flaky.
The flakiness is unavoidable because we are stuck between the world of
MS-DOS keyboard TSRs like KEYB (which wants to cook the data;
important for international) and the world of Win32.
So keys that don't "exist" in MS-DOS land (like dead keys) have a
very tenuous existence in Win32 console land. Keys that act
differently between MS-DOS land and Win32 console land (like
capslock) will act flaky.
Don't even _mention_ the problems with multiple language keyboard
layouts...
You may be able to fashion some sort of workaround with the digraphs
mechanism. |digraphs|
The best solution is to use the Win32 GUI version gvim.exe. Alternatively,
you can try one of the DOS versions of Vim where dead keys reportedly do
work.
Q. How do I type dead keys on Windows NT?
A. Dead keys work on NT 3.51. Just type them as you would in any other
application.

< The first command runs notepad minimized and the second one runs it

Q. I'm using Win32s, and when I try to run an external command like "make",
Vim doesn't wait for it to finish! Help!
A. The problem is that a 32-bit application (Vim) can't get notification from
Windows that a 16-bit application (your DOS session) has finished. Vim
includes a work-around for this, but you must set up your DOS commands to
run in a window, not full-screen. Unfortunately the default when you
install Windows is full-screen. To change this:
1) Start PIF editor (in the Main program group).
2) Open the file "_DEFAULT.PIF" in your Windows directory.
3) Changes the display option from "Full Screen" to "Windowed".
4) Save and exit.
To test, start Vim and type >
:!dir C:\<CR>".
< You should see a DOS box window appear briefly with the directory listing.
Q. I use Vim under Win32s and NT. In NT, I can define the console to default to
50 lines, so that I get a 80x50 shell when I ':sh'. Can I do the same in
W3.1x, or am I stuck with 80x25?
A. Edit SYSTEM.INI and add 'ScreenLines=50' to the [NonWindowsApp] section. DOS
prompts and external DOS commands will now run in a 50-line window.
