Deployment Method:


This applies to both open source and commercial editions of Chocolatey.

1. Enter Your Internal Repository Url

(this should look similar to https://community.chocolatey.org/api/v2/)

2. Setup Your Environment

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

2. Get the package into your environment

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Copy Your Script

choco upgrade choco-optimize-at -y --source="'INTERNAL REPO URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade choco-optimize-at -y --source="'INTERNAL REPO URL'" 

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0

Exit $exitCode

Package Approved

This package was approved by moderator gep13 on 11 May 2018.


choco-optimize-at periodically reduces the size of downloaded Chocolatey .nupkg package files thus saving HDD space. This package creates a Windows Scheduled Task to run "choco optimize" at a time you specify.


choco-optimize-at is designed for Chocolatey Pro and Chocolatey Business licensed users who want to automate optimization of storage space used by their Chocolatey .nupkg files.


You can install choco-optimize-at with multiple parameters to make it run "choco optimize" daily or weekly at your preferred time. If you enter no parameters at all, choco-optimize-at will default to run "choco optimize" at 5 AM every SUNDAY. When entering the TIME parameter, use "Military Time." When entering the DAILY or WEEKLY parameter you can actually use anything, "yes" just makes sense though. When using the WEEKLY parameter, DAYS are entered as MON, TUE, WED, THU, FRI, SAT, or SUN. Not entering the correct format will fail the install. Please see the examples below.


  • choco install choco-optimize-at - optimizes packages on SUNDAYS at 5 AM. (My preference!)
  • choco install choco-optimize-at --params "'/TIME:23:00'" - optimizes packages on SUNDAYS at 11 PM
  • choco install choco-optimize-at --params "'/DAILY:yes /TIME:06:00'" - optimizes packages daily at 6 AM
  • choco install choco-optimize-at --params "'/WEEKLY:yes /DAY:SAT /TIME:01:00'" - optimizes packages on SATURDAYS at 1 AM


  • If you don't specify any parameters, choco-optimize-at defaults to running every Sunday at 5 AM. (My preference!) This default time was chosen to be compatible with with default run times used by choco-upgrade-all-at and choco-persistent-packages.
  • Not specifying a time will always default to 5 AM.
  • When WEEKLY is specified but a DAY isn't, default first run will be a week from installation date; i.e. next week on whatever day of the week you installed the package.

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
