Excellent 😊 more enhancements coming soon
Hi potatoqualitee,
Thanks for you great work. I am novice to Powershell and started learning about it. you script(https://github.com/potatoqualitee/kbupdate) worked for me, but only problem is it downloads all available package with same name.
For example, KB4522007. when i try your script to download, it downloads all available KBs. I want to download for 'Win2012R2' only but it downloads for all.
*Save-KbUpdate KB4522007 -Architecture x64 -OperatingSystem 'Windows Server 2012 R2' -Path C:\softarc*
WARNING: [10:11:38][Save-KbUpdate] When piping, please do not use OperatingSystem or Product filters. It's assumed that you are piping the results that you wish to download, so unexpected results may occur.
Thanks potatoqualitee ! The script works great. Only thing is had to change HTTP to HTTPS on line # 58 and 85 to make it work.

Hi.
I tried using this script (with Admin privileges), and the following command:
.\Save-KBFile -Name KB4057119
.\Save-KBFile -Name KB4057120
.\Save-KBFile -Name KB4057121
It won't download any file to current directory. What am I missing? There is no error message at all.
Thanks!
