Uninstall for Windows is a shareware product. This means that you can find
UN4WIN in and download it from many sources, but that the author reserves
all rights.

Shareware Defined

Perhaps the best way to define shareware is to explain what it is not.

Shareware is not free software. Unlike Public Domain and Freeware, all rights
are reserved by the author, and he may charge any fee or impose any trial
period he sees fit upon its use. Public Domain software is software that has
been dedicated to and released for the public good, and may be used in any
manner by any party. Freeware is software for which no fee is charged, but in
which the author maintains the copyright and may thus dictate the terms under
which it may be used. Once again, UNINSTALL FOR WINDOWS IS SHAREWARE.

The accompanying text editor, TE.EXE, that is distributed with Uninstall for
Windows is an example of Public Domain Software. We did not write it, and
claim no rights to it.

Why use Uninstall for Windows?

Everybody who's used Microsoft Windows for more than a few days has come up
against a problem. With very few exceptions, there's no good way to remove a
program written for the environment from your system, if you decide you don't
want it there anymore.

With DOS programs, the problem usually isn't severe. More often than not, all
you need to do to remove a DOS-based program is delete the directory in which
it has been installed, plus its contents. Sometimes there will be changes made
to the system files AUTOEXEC.BAT and CONFIG.SYS, but those files almost always
reside in the root directory of your first hard drive (C:\), and x86-based
computer users have become used to dealing with those files on a regular basis.

Under Windows, though, the situation gets ugly. You still need to keep track of
AUTOEXEC.BAT and CONFIG.SYS, but there's much more to worry about. Some
programs install in their own directories, while others get thrown in with
Windows itself. Sometimes you get a choice of where to locate the software,
other times not. Even when you think you've isolated your new program, it often
proves to be spread about your system in a way that makes its removal all but
impossible. Files end up in the SYSTEM subdirectory of WINDOWS, .INI files can
be in the subdirectory you specify or in the Windows directory, changes are
often made to WIN.INI -- the list of potential problems goes on and on.

Uninstall for Windows solves this problem, simply, quickly, and easily. All
you do is copy the files to any directory on the same drive where you've
installed Microsoft Windows, and run it before you install a new application or
utility program. Invoke the "system survey" option, and the state of your
system is captured for comparison against its condition after the new software
has been installed.

Using Uninstall for Windows

First of all, we need to make a point.

Uninstall for Windows is designed to help you overcome a problem that occurs
as a result of using the Microsoft Windows graphical environment. Yet, we have
delivered UN4WIN as a native DOS application, instead of a Windows program.
Why? There are two reasons: since the information that UN4WIN deals with
originates at DOS level, we thought it more honest to treat it accordingly.
Also, by making UN4WIN a DOS program, we are able to deliver it in a much
smaller packages than if we burdened it with the overhead inherent to Windows
software. Since Uninstall for Windows is so easy to use, there isn't even an
issue over interface - there's just one menu with five choices - do you REALLY
need 3-D buttons for that? Of course not!

At the same time, we recognize that many users NEVER "drop to DOS". So, we
have provided icon and program information files that let you set up
Uninstall for Windows to run directly from Windows at the click of a mouse.

Setting up the program

This is easy. Just copy the files to any directory ON THE SAME HARD DRIVE ON
WHICH YOU HAVE Windows INSTALLED. You will need UN4WIN.EXE and TE.EXE, and
we also recommend keeping this file, UN4WIN.DOC. However, if you plan to run
Uninstall for Windows from DOS, or using a command line from within Windows
(instead of clicking on an icon), you won't need UN4WIN.ICO. Similarly, we
provide UN4WIN.PIF strictly as a convenience -- it will use only 160 kilobytes
of memory, but there really isn't anything else special about it, so you can
run UN4WIN without it. Of course, you also won't need it if you run the program
from DOS or a DOS session under Windows.

If you decide to set up Uninstall for Windows to run under Windows using the
included .ICO and .PIF files, here's what you do (instructions are for Program

1) Display the program group where you want the UN4WIN icon to be, and use
the "NEW" command on the File menu. Make sure that "Program Item" is
marked, and click "OK".
2) Put whatever name you like -- we recommend "Uninstall for Windows" -- in
the description box.
3) In the command line box, point your system to the directory where you are
keeping the UN4WIN files, and either the UN4WIN.EXE program, or UN4WIN.PIF
if you are using it. For example, if you are keeping the files in your
Windows directory, and Windows is installed on your "C:" drive, and you
have decided to use the .PIF, then you would type (omitting the quotes)
4) Click the "OK" button.

Is it better to put the Uninstall for Windows files in their own directory, or
in with Windows? You'll have to decide this issue for yourself; putting the
files in your Windows directory makes sense, and will cause no problems, but if
clutter bothers you, you'll probably prefer to create a separate directory for
UN4WIN. This seems like a bit of a waste, since there are so few files in the
package and they are easily identifiable by the "UN4WIN" prefix, but it's our
job to give you the facts, not tell you what to do.

Page 8

You should be aware of one more thing: during its first step, surveying your
system, UN4WIN creates quite a few files that are left on your disk until
you run the comparison that enables you to restore your system to the state
it was in before you installed your new Windows software. Many people will
consider this a pretty good argument for giving Uninstall for Windows its own

Running Uninstall for Windows

Start Uninstall for Windows either by changing to the DOS drive and directory
where you have placed the files, typing "UN4WIN", and tapping the key,
or by double clicking the icon you created in Windows when you followed the
steps outlined above. You will see the following screen:

Uninstall for Windows, v1.5

Do a System Survey
Compare Old System to New
Look at Report

Quit and return to DOS

Please make a choice :

COPYRIGHT (c) 1992-93


You can view this file anytime you see the menu, just by tapping the "H" key.
WARNING: you can also CHANGE this file, so be careful, and make sure you
don't lose the original! The "Q" option is available all the time, too.

The other three options control the actual operation of Uninstall for Windows.
"L", (look) lets you view the file REPORT.TXT, which is created by using
Uninstall for Windows to compare the before and after statuses of your system
around an installation of other software. If the file doesn't exist (as it
won't when you first introduce UN4WIN to your system), you will be told as much
and returned to the menu.

Page 9

Choice "A" runs the survey process that tells Uninstall for Windows about your
system, and should be used immediately before installing any new software. When
you are done installing a new Windows program, use "B" to compare your system
before and after the installation. Like the report viewing option, these two
selections will tell you if you are using them incorrectly.


You should RUN your new software before using choice "B". While many software
titles make all the changes they will ever effect during installation, OTHERS
WAIT UNTIL YOU RUN THEM FOR THE FIRST TIME, and some even wait until you close
them down.

The correct flow for using Uninstall for Windows is this:

1) Use choice "A" to survey your system.
2) Install your new Windows application.
3) Run your new Windows application.
4) CLOSE the new program
5) Use choice "B" to compare what your system looked like before software
installation to how it is afterward.
6) After you have created REPORT.TXT, we recommend examining it to see the
changes to your system. While this is NOT mandatory (the information will
THE FILE WILL BE DELETED. We recommend changing the name of the REPORT.TXT
file to another name that you consider meaningful in identifying the
program that you used Uninstall for Windows to protect the integrity of
your system against. This can be done with the DOS "REN" command, or
whatever other DOS or Windows utility you prefer.



The REPORT.TXT file contains a lot of information. It tells you what new
directories have been created anywhere in your system, what new files have
been created in the root directory of your C: drive, the WINDOWS directory, and
the SYSTEM subdirectory of Windows. It also logs changes to WIN.INI, SYSTEM.INI,
C:\AUTOEXEC.BAT, and C:\CONFIG.SYS. This is a complete list of the variables
that are effected by any Windows program that we have seen, with one exception:
lately, we've seen a few programs that add menus to File Manager. IF YOU EVER

Using the information in REPORT.TXT is fairly straightforward. When you want to
uninstall a program, examine the file, and note the following:

1)Any directories that have been created (and their contents) can be
deleted. They will be noted in the section of REPORT.TXT marked

"[Directory trees for all drives in this system]"

For example, In every system there will be a line that says "Comparing
files TREE-C.OLD and TREE-C.NEW". Under this line will be a listing of any

Page 10
new directories on the C: drive. Likewise, if you install your new program
on the G: drive of a system so equipped, there will be a line that reads
"Comparing files TREE-G.OLD and TREE-G.NEW".

2)If any changes have been made to the file WIN.INI (located in your WINDOWS
directory), they will be noted in the section marked


The changes that can be listed hear are too numerous to list, but the main
point is that anything that is in the WIN.INI that was not in WIN.OLD can
usually be deleted. Treat the changes found under the heading



3)Sometimes, a program will modify C:\CONFIG.SYS and C:\AUTOEXEC.BAT. It's
rare, fortunately, that these changes are made without backup copies being
created first, but we don't want to take that for granted, do we? You will
find sections marked


to help you here. Changes made to these files can vary, but they are
usually limited to only a few choices when made by Windows programs. SET
commands and lines that load special pieces of software called device
drivers will be added to CONFIG.SYS ("device="), and the PATH statement
in your AUTOEXEC.BAT file is frequently appended with the name of the
directory in which you installed your new software. simply use TE.EXE or
any other text editor to restore these files to their earlier condition,
if you need to uninstall something.

4)In the section headed with


you will find the results of a comparison of the contents of those two
directories before and after you installed new software. Simply put, there
are many programs that put files in these two places. You will likely find
unusual .INI files in the WINDOWS directory (but there could be almost
anything), and most of the time you will find that the files left in
WINDOWS\SYSTEM end with the extension .DLL. How do you deal with these?
Usually, you will just delete the new files that your new software gave
you, but there are exceptions. For example, in Windows 3.1 there is a file
called COMMDLG.DLL that controls the appearance of most dialog boxes. You
may find that you have before and after listings that look as if you have
a different version of this file than you started with. You wouldn't want
to delete this new file unless you were planning to restore the original
one from your Windows program disks. However, when changes like this occur

Page 11

they usually mean that Microsoft has released an update of the file to
software developers, and that the installation routine accompanying your
new software has put it on your system.

5)The last section of REPORT.TXT lists any new files that have been added to
the root directory of your C:\ drive. An example of files that are
treated this way are special device drivers that have been designed to
work with more than just your new program. These files are expendable by
definition once you remove the software that they came with, but if you
encounter any it's probably a good idea to use the software developer's
technical support services to find out precisely what purpose they serve.

There are two other situations that need some explanation. Look at this:

[Directory Trees for all drives in this system]
Comparing files TREE-F.OLD and TREE-F.NEW
FC: no differences encountered

Comparing files TREE-E.OLD and TREE-E.NEW
***** TREE-E.OLD
213 file(s) 0 bytes
5988352 bytes free
***** TREE-E.NEW
213 file(s) 0 bytes
5980160 bytes free

This is the result of before and after comparison of the directory structures of
the E: and F: drives on a system. It appears to say that there are not any
changes on E:, so why is there information included in the report instead of
the simple "no differences encountered" message?

When you look a little closer, you'll notice that the "bytes free" figures
don't match. Is this a problem? No! The number reflect the fact that Uninstall
for Windows had created a few temporary files, and that they still existed
when the report was created.

Page 12

The second puzzling piece of output you'll encounter is this:

disablewarning=true (a right-pointing arrow -- STRAY END-OF-FILE
MARKER -- can show up here)

Notice that the before and after listings here for the SYSTEM.INI file are
identical except for the parenthetic note we've added at the end. What does
this note mean?

The "end of file" marker (ASCII decimal 26, hex 1A for technical types) is a
special "control character" that some (but not all) software places, as you've
guessed, at the end of a file. We can't safely insert it in the middle of
this file, and you probably couldn't print it, which explains why we've made
that notation above instead of just showing the character. The fact that it's
in REPORT.TXT is only partially explainable.

When REPORT.TXT is created, it compares certain other files and memory
variables to each other. Sometimes this results in the insertion of this stray
character even though it doesn't belong there and doesn't even really exist!

When you use TE.EXE (which is also called internally by Uninstall for
Windows) to view REPORT.TXT, any of these characters will show up in their
native form. If your REPORT.TXT file includes any sections that show this
character as the only difference, they may simply be ignored.

Miscellaneous Subjects

Since the REPORT.TXT file is composed of regular ASCII text strings that can
be displayed by almost any program we can think of, you might wonder why we
have bothered to include TE.EXE in this package. The answer is as simple as
using the DOS command "TYPE REPORT.TXT". This command, and many DOS-based
word processors and text editors, chokes on those pesky end-of-file characters.
While the two editors included with Windows (Notepad and Write) can both handle
the characters properly, we didn't think it was a good idea to force you to use
those, especially since many users remove them from their systems. Also, since
Uninstall for Windows was written as a DOS program, it wouldn't make much sense
to force you into Windows to read its output.

Page 13

We do not support TE, beyond echoing here the instructions you will encounter
while using Uninstall for Windows. , followed by "Y" for yes and "1", "2",
or "3" to indicate which parallel port your printer is attached to (usually
"1") lets you print the file you are reading, and exits TE.

We don't recommend running Uninstall for Windows while you are logged on to a
network. There are no problems that will cause damage of any sort, but the
information you get in REPORT.TXT might not be accurate. If possible, log off
before running Uninstall for Windows.

If you use Stacker with SSWAP (version 3.0 or earlier), SuperStor, or any other
utility that causes your system to see drives with different letter assignments
than are accurate as DOS boots, Uninstall for Windows will not be able to
survey your CONFIG.SYS and AUTOEXEC.BAT files or root directory on the C:
drive. We've long recommended against using these utilities in our consulting
and publishing endeavors, and here's a great example of why. The most recent
versions of these products, including DOS 6's DoubleSpace, DO NOT HAVE THIS
PROBLEM, bacause the compressed drive that becomes "C:" is also the place where

Finally: during operation you may see a few "File not found" messages scroll
by on your screen. They reflect the interim status of your system while
Uninstall for Windows is running, and may be ignored.

Changes in Version 1.1

We came across two major problems with the design of Uninstall for Windows in
version 1.0.

First (and thanks to the MANY people who contacted us about this), version 1.0
would only work on systems where Windows was installed in a directory named
\WINDOWS. This is no longer the case. Now, UN4WIN prompts you to supply the name
of Windows' home when you run it, and if you type a directory name that doesn't
exist, tells you so.

Second, we came across intermittent problems when UN4WIN was run on computers
with CD-ROM drives installed and currently available. We took the easy way out
on this one: since there won't be any changes for UN4WIN to ferret out on these
read-only drives, you are simply given the chance to identify them to UN4WIN,
and the program won't try to search them.

Changes in Version 1.5

Uninstall for Windows now operates properly in systems employing the "/p"
parameter of the SET DIRCMD= command available in version 5.0 and later of DOS.

You can now rename and/or move REPORT.TXT after you have created it, right
inside UN4WIN. We recommend using this enhancement as follows: Copy REPORT.TXT
to the home directory of the application for which the information in it
applies. Either name the files consistently according to the name of the
application (for example, "U4WEXCEL.TXT for Excel), or just keep the name
REPORT.TXT (in as many places as is necessary).

Page 14

The program now checks to make sure you have at least one megabyte of available
disk space when you run it. While this is actually A LOT more than most people
will need to use UN4WIN successfully, we thought it safer to err on the
conservative side of things.

Some items are now color-coded. Not a big deal, but a few people asked for it,
so here it is.

Certain screens displays that used to lag have been made faster.


In the section of REPORT.TXT dealing with directories, you may find anywhere
from a few to a few hundred references to the dirctories "." and ".." .
Specifically, these refer to the file entries for the directory in which you
currently reside (.) and the parent directory of that location (..) . You'll
notice that these entries only appear in SUBDIRECTORIES, since their purpose
is moot in the root directory of any drive. In most cases, these entries can be
ignored. While there will be an occasional program that drops pieces of itself
in newly-created subdirectories of programs other than itself, we've never seen
that happen except as a subdirectory of Windows (most Microsoft products create
"MSAPPS" there, for example). We know how frustrating it can be to plow through
page after page of this stuff, but there are occasions when it proves to be
SEARCH command is -, .

We are aware that Uninstall for Windows doesn't always work correctly when
alternate command processors like NDOS or 4DOS are used in place of COMMAND.COM.
Although we have not yet figured out a solution for this (and in fact suspect
that there is none), we can report that you can solve the immediate problem by
invoking an instance of DOS' COMMAND.COM underneath the alternate.
