Windows 10 Feature Upgrade - Powershell not working anymore

mathieucohen · 2023-09-14T23:10:14.000Z

Hi Spicies,

Been a while since i’ve posted but I have a little annoying issue with a script I had been using for years now that started failing few months back, I haven’t spent much time looking into it and I’m by no means a Powershell Guru and was wondering if anyone could point to the right direction.
The script is to automatically proceed with a Windows 10 Feature upgrade. We were using it everytime we onboarded new clients who would have workstations with w10 versions older than 1903 as Feature upgrades weren’t part of WUS before then.
The script seems to fail at the download portion and it skips quickly to the install portion, which ultimately fail because the file does not exist.
Anyone can see why this script wouldn’t work anymore?
Thanks!

It downloads for me just fine.

What is the error message? You can add transcript logging to see what the error says

Start-Transcript -Path "c:\windows\temp\logfile.txt
# your code
Stop-Transcript

How are you running the script ? via GPO at user per profile or GPO at per machine profile ?
