Evergreen is a simple PowerShell module to return the latest version and download URLs for a set of common enterprise Windows applications. The module consists of a number of simple functions to use in scripts when performing several tasks including:
Retrieve the latest version of a particular application when comparing against a version already installed or downloaded
Return the URL for the latest version of the application if you need to download it locally for installation or deployment
Right now all functions consist of the following:
Get verb - the module provides functions to retrieve data only
Vendor - the vendor / developer of the application (e.g.
Product name - product names and optionally version (e.g.
This may change in a future release to simplify commands where the application can be a parameter or input into Evergreen to return the details for that application (e.g.
Get-Evergreen -App "MicrosoftEdge").
There are several community and commercial products that manage application deployment and updates already. This module isn't intended to compete against those. In fact, they can be complementary - for example, Evergreen can be used with the Chocolatey Automatic Package Updater Module to find the latest version of an application and then creating and submitting a Chocolatey package, or it can be used to create a Windows Package Manager manifest (see a sample script here: New-WinGetManifest.ps1).
Evergreen's focus is on integration for PowerShell scripts to provide product version numbers and download URLs. Ideal for use with the Microsoft Deployment Toolkit or Microsoft Endpoint Configuration Manager for operating system deployment, creating applications packages in Microsoft Intune, or with Packer to create evergreen machine images in Azure or AWS.
Application version and download links are only pulled from official sources (vendor web site, GitHub, SourceForge etc.) and never a third party.
Wherever possible, Evergeen uses an approach that returns at least the verison number and download URI for applications programatically - thus for each run an Evergreen function it should return the latest version and dowload link.
Scraping web pages to parse text and determine version strings and download URLs can be problematic when text in the page changes or the page is out of date. Evergreen instead uses approaches that should be less prone to failure by querying an API wherever possible. Evergreen uses several strategies to return the latest version of software:
Web page queries - often a vendor download pages will include a query when listing versions and download links - this avoids page scraping. Evergreen can mimic this approach to return application download URLs; however, this approach is likely to fail if the vendor changes how their pages work - e.g. Microsoft FSLogix Apps or Zoom
Evergreen supports Windows PowerShell 5.1 and PowerShell 7.0+. Evergreen should work on PowerShell Core 6.x; however, we are not actively testing on that version of PowerShell, so support cannot be guaranteed.
This module is maintained by the following community members
The module uses a version notation that follows: YearMonth.Build. It is expected that the module will have changes on a regular basis, so the version numbering is intended to make it as simple as possible to understand when the last update was made. See the CHANGELOG for details on changes introduced in each version.
