@subsection How do I uninstall @strong{all} of Cygwin?
Setup has no automatic uninstall facility. Just delete everything
manually:
Setup has no automatic uninstall facility. The recommended method to remove all
of Cygwin is as follows:
@itemize @bullet
@item Cygwin shortcuts on the Desktop and Start Menu
@enumerate
@item The registry tree @samp{Software\Cygnus Solutions} under
@code{HKEY_LOCAL_MACHINE} and/or @code{HKEY_CURRENT_USER}.
@item Remove all Cygwin services. If a service is currently running, it must
first be stopped with @samp{cygrunsrv -E name}, where @samp{name}
is the name of the service. Then use @samp{cygrunsrv -R name} to uninstall the
service from the registry. Repeat this for all services that you installed.
Common services that might have been installed are @code{sshd}, @code{cron},
@code{cygserver}, @code{inetd}, @code{apache}, and so on.
@item Anything under the Cygwin root folder, @samp{C:\cygwin} by
default.
@item Anything created by setup in its temporary working directory.
@end itemize
It's up to you to deal with other changes you made to your system, such
as installing the inetd service, altering system paths, etc. Setup
would not have done any of these things for you.
If you want to save your mount points for a later reinstall, save the
output of @samp{mount -m} as described at
@item Stop the X11 server if it is running, and terminate any Cygwin programs
that might be running in the background. Remove all mount information by typing
@samp{umount -A} and then exit the command prompt and ensure that no Cygwin
processes remain. Note: If you want to save your mount points for a later
reinstall, first save the output of @samp{mount -m} as described at
@file{http://cygwin.com/cygwin-ug-net/using-utils.html#mount}.
@item Delete the Cygwin root folder and all subfolders. If you get an error
that an object is in use, then ensure that you've stopped all services and
closed all Cygwin programs. If you get a 'Permission Denied' error then you
will need to modify the permissions and/or ownership of the files or folders
that are causing the error. For example, sometimes files used by system
services end up owned by the SYSTEM account and not writable by regular users.
The quickest way to delete the entire tree if you run into this problem is to
change the ownership of all files and folders to your account. To do this in
Windows Explorer, right click on the root Cygwin folder, choose Properties, then
the Security tab. Select Advanced, then go to the Owner tab and make sure your
account is listed as the owner. Select the 'Replace owner on subcontainers and
objects' checkbox and press Ok. After Explorer applies the changes you should
be able to delete the entire tree in one operation. Note that you can also
achieve this in Cygwin by typing @samp{chown -R user /} or by using other tools
such as CACLS.EXE.
@item Delete the Cygwin shortcuts on the Desktop and Start Menu, and anything
left by setup.exe in the download directory. However, if you plan to reinstall
Cygwin it's a good idea to keep your setup.exe download directory since you can
reinstall the packages left in its cache without redownloading them.
@item If you added Cygwin to your system path, you should remove it unless you
plan to reinstall Cygwin to the same location. Similarly, if you set your
CYGWIN environment variable system-wide and don't plan to reinstall, you should
remove it.
@item Finally, if you want to be thorough you can delete the registry tree
@samp{Software\Cygnus Solutions} under @code{HKEY_LOCAL_MACHINE} and/or
@code{HKEY_CURRENT_USER}. However, if you followed the directions above you
will have already removed all the mount information which is typically the only
thing stored in the registry.
@end enumerate
@subsection How do I install snapshots?
First, are you sure you want to do this? Snapshots are risky. They
