Hello, I tried the script and it updates the IPv4 DNS settings, but the script fails on the next steps (on Windows 11 Home 22631.2715):

+     Invoke-GPUpdate /Force
+     ~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Invoke-GPUpdate:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

+     Set-ItemProperty -Path "HKLM:\Software\Policies\Microsoft\Windows ...
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (HKLM:\Software\...ws NT\DNSClient:String) [Set-ItemProperty], ItemNotFoundException
    + FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.SetItemPropertyCommand

Do you think that this is important? I think the following line explains the cause of both errors; should I install RSAT Tools?

Invoke-GPUpdate is part of the GroupPolicy module. GroupPolicy is not available by default, but is included with RSAT Tools.

Thank you so much

interesting, haven't noticed that, can you confirm it works without Group Policy update? it shouldn't in some cases, on Pro I have to run it
