Find installed ArcGIS patches on the computer

Summary

It is common to use the ArcGIS Enterprise Patch Notification utility to check what patches are installed, or use the About ArcGIS Pro page to see the currently installed version of ArcGIS Pro. However, there is another 'one-stop shop' to identify the ArcGIS patches installed on Windows, PowerShell. This may be helpful when trying to view all patches installed in one place there are several products installed on the same machine, or when trying to cross-reference/verify that a patch is installed via any kind of necessary troubleshooting steps.

Procedure

1. Run PowerShell as Administrator.
2. Run the following command:

Get-Package | Where-Object { $_.Name -like "*ArcGIS*" } | Format-Table -Wrap -AutoSize

This command searches for all installed packages with "ArcGIS" in the name, and the output table is formatted so that the rows are stretched to ensure all text is visible as shown in the next image.

Notice that all of the different ArcGIS programs installed on the machine are listed here (ArcGIS Server, Portal for ArcGIS, ArcGIS Data Store, ArcGIS Pro, etc.).

Note: 
This example is a test environment. In most cases, ArcGIS software is installed across various machines, and it is necessary to run the command on each machine where the software is installed.
