Uninstall Command

Uninstalls a package or a list of packages.

Chocolatey automatically tracks registry changes for "Programs and
 Features" of the underlying software's native installers when
 installing packages. The "Automatic Uninstaller" (auto uninstaller)
 service is a feature that can use that information to automatically
 determine how to uninstall these natively installed applications. This
 means that a package may not need an explicit chocolateyUninstall.ps1
 to reverse the installation done in the install script.

Chocolatey tracks packages, which are the files in
 `$env:ChocolateyInstall\lib\packagename`. These packages may or may not
 contain the software (applications/tools) that each package represents.
 The software may actually be installed in Program Files (most native
 installers will install the software there) or elsewhere on the
 machine.

With auto uninstaller turned off, a chocolateyUninstall.ps1 is required
 to perform uninstall from the system. In the absence of
 chocolateyUninstall.ps1, choco uninstall only removes the package from
 Chocolatey but does not remove the software from your system (unless
 in the package directory).

NOTE: A package with a failing uninstall can be removed with the
`-n --skipautouninstaller` flags. This will remove the package from
chocolatey without attempting to uninstall the program.

NOTE: Chocolatey Pro / Business automatically synchronizes with
 Programs and Features, ensuring manually removed apps are
 automatically removed from Chocolatey's repository.

NOTE: Synchronizer and AutoUninstaller enhancements in licensed
 versions of Chocolatey ensure that Autouninstaller is up to 95%
 effective at removing software without an uninstall script. This is
 because synchronizer ensures the registry snapshot stays up to date
 and licensed enhancements have the ability to inspect more locations
 to determine how to automatically uninstall software.

Usage

    choco uninstall <pkg|all> [pkg2 pkgN] [options/switches]

NOTE: `all` is a special package keyword that will allow you to
 uninstall all packages.

 write proper scripts and integrations.


Exit Codes

Exit codes that normally result from running this command.

Normal:
 - 0: operation was successful, no issues detected
 - -1 or 1: an error has occurred

Package Exit Codes:
 - 1605: software is not installed
 - 1614: product is uninstalled
 - 1641: success, reboot initiated
 - 3010: success, reboot required
 - other (not listed): likely an error has occurred

In addition to normal exit codes, packages are allowed to exit
 with their own codes when the feature 'usePackageExitCodes' is
 turned on.

Reboot Exit Codes:
 - 350: pending reboot detected, no action has occurred
 - 1604: install suspended, incomplete

In addition to the above exit codes, you may also see reboot exit codes
 when the feature 'exitOnRebootDetected' is turned on. It typically requires
 the feature 'usePackageExitCodes' to also be turned on to work properly.

Options and Switches

NOTE: Options and switches apply to all items passed, so if you are
 installing multiple packages, and you use `--version=1.0.0`, it is
 going to look for and try to install version 1.0.0 of every package
 passed. So please split out multiple package calls when wanting to
 pass specific options.
