It’s no longer necessary to use Internet Explorer for downloading Windows Updates (.msu update packages for offline install or distribution) from the Microsoft Update catalog. The Microsoft Update catalog now supports any browser, as Microsoft has revamped the site and eliminated the ActiveX Control.
This article tells you how to download updates from the Microsoft Update catalog using your web browser or PowerShell.
Download Updates Directly from Microsoft Update Catalog

Right-click on the .msu or .cab link and choose Save target as to download the file locally.

Method 2: Using PowerShell to download Windows Update Packages
Save-KBFile PowerShell Script (created by a Microsoft MVP) loads and parses the MU catalog in the background and downloads updates using BITS to your preferred folder.

Save-KBFile.ps1to a folder — e.g.,
Option A: Download updates in a single click – The easiest option
To download updates using the PowerShell script, create a desktop shortcut with the following target and run it:
powershell.exe -ExecutionPolicy Bypass -command . D:\Scripts\Save-KBFile.ps1; Save-KBFile -Name KB4509091 -Architecture x64 -Path D:\Updates"
To download a different update (KB##) or for a different architecture (x86), change it in the shortcut properties.
Option B: Open PowerShell and run the command manually
- Right-click Start, click Run. Type the following command and click OK:
powershell.exe -noexit -ExecutionPolicy Bypass -File "D:\Scripts\Save-KBFile.ps1"
You can create a desktop shortcut to the above command if you’re going to use it frequently.
- Run the Save-KBFile script to download Windows updates (.msu) using the following command-line syntax:
Download KB4509091 to the current directory. If the architecture is not mentioned, by default, it downloads the 64-bit version of the update.
Save-KBFile -Name KB4509091 -Architecture x64 -Path D:\Updates
To download the 32-bit update, run:
Save-KBFile -Name KB4509091 -Architecture x86 -Path D:\Updates

Save-KBFile -Name KB4509091 -Architecture All -Path D:\Updates
To download multiple updates, and to a specific folder:
