PSWindowsUpdate Packages

Purpose:

You are looking for a WSUS/Microsoft Update replacement integrated with PDQ Products to ensure that endpoints have all available patches from Microsoft.

Overview:

Although we currently offer Microsoft Cumulative Updates in our Package Library, we frequently have customers asking about a full WSUS/Microsoft Update replacement integrated into our products. While we typically avoid third-party tools, the PSWindowsUpdate module is well-known and widely used for checking and applying all available Microsoft updates to a machine and can be a viable alternative to WSUS/Microsoft Update. This is also an advantage for Connect customers, having the Microsoft Updates downloaded directly from Microsoft servers instead of a traditional on-premise server.

If you are a military or government organization, you may want to review this PowerShell Module in greater detail before placing it into production to ensure that it meets your security standards:

Publisher: PowerShellGallery

Download: PSWindowsUpdate

VirusTotal: Report

Requirements:

1. Endpoints must have internet access. These packages will not work on air-gapped networks.

2. PowerShell scripts must be enabled and allowed to run on endpoints.

3. Endpoints must have access to Microsoft servers to download updates.

Getting Started:

There are currently 6 Packages in the Package Library available for you to use:

1. PSWindowsUpdate - Get All Applicable Updates from Microsoft (Audit Only)

2. PSWindowsUpdate - Install All Applicable Updates from Microsoft (No Drivers, No Feature Updates)

3. PSWindowsUpdate - Install All Applicable Critical and Security Updates from Microsoft

4. PSWindowsUpdate - Install All Applicable Drivers from Microsoft

5. PSWindowsUpdate - Install All Applicable Feature Updates from Microsoft

6. PSWindowsUpdate - Install Specific Microsoft KB

Each of these packages will do the following:

1. Check if the PSWindowsUpdate module is installed. If it is not, it will download the Nuget Installer and then download the PSWindowsUpdate module.

2. It will then Run the PSWindowsUpdate module and check for all available Microsoft patches.

3. Depending on the package, it will then install specific updates.

4. Reboots are disabled, but may be required in order to complete the installation of some patches.

PACKAGE: Get All Applicable Updates from Microsoft (Audit Only)

This package is an Audit-Only package. You can run this and then view the Output log to see what applicable Microsoft Updates are available for the endpoint. You can then choose which other PSWindowsUpdate packages to use to install a subset or all of the updates on the machine.

PACKAGE: Install All Applicable Updates from Microsoft (No Drivers, No Feature Updates)

This package will install ALL applicable updates from Microsoft, but will not install hardware drivers or feature updates.

PACKAGE: Install All Applicable Critical and Security Updates from Microsoft

This package will install Critical and Security Patches ONLY. This package will install cumulative updates as well as other critical updates and security updates.

PACKAGE: Install All Applicable Drivers from Microsoft

There are many hardware drivers now available from Microsoft to update, including but not limited to printers, video, mice, keyboards, network, and third-party firmware drivers. We strongly recommend additional testing, especially with network and firmware drivers on test machines or a test lab before deploying to remote machines and risking OS or network connectivity issues with installation failure.

PACKAGE: Install All Applicable Feature Updates from Microsoft

This package will specifically install Feature Updates. Please note that Feature Updates can take quite a bit of time to download and install, so you may need additional contact with end users to coordinate a block of time for a feature update (overnight deployment).

PACKAGE: Install Specific Microsoft KB

This package currently is only applicable for PDQ Deploy and gives you the ability to directly modify the KB Number you wish to deploy in the Parameters field in Step 1. Please pay close attention to preserving the exact syntax in the Parameters field:

Example 1 with one KB Number:

-KBArticleID 'KB8675309'

Example 2 with 2 or more KB Numbers to install:

-KBArticleID 'KB8675309, KB9274836, KB3371337'

Customizing PSWindowsUpdate for your own Environment:

While the default packages above will be a suitable WSUS/Microsoft Update alternative for the majority of our customers, If you are comfortable with PowerShell, You can download any of the PSWindowsUpdate packages (With the exception of the Specific Microsoft KB package) and convert the auto-download package to a standard package. Then you can browse to the PowerShell file in Step 1 and there are many different options to target and install updates specifically:

Full Script: Install Specific Microsoft KB

This script includes an additional parameter block to change and read the KBNumber you wish to deploy:

[CmdletBinding()]param ([Parameter(Mandatory = $true)][String]$KBArticleID)Write-Host "KBArticleID is $KBArticleID"

The PowerShell script then looks for an additional parameter when running the script:

-KBArticleID 'KB8675309'
