Hi @dramaticrobotic ,
You can try the following from PowerShell:

powershell -exec bypass -c "(New-Object Net.WebClient).Proxy.Credentials=[Net.CredentialCache]::DefaultNetworkCredentials;iwr('https://gist.githubusercontent.com/mavaddat/24a03fd07aa059806d58c39b06acee70/raw/bc7b1ee6c5f6b95fd7d083e6f0cfc1d86130c8ee/resetWindowsUpdate.ps1')|iex"
