A couple of days ago I updated to Windows 10 20H2 and was immediately hit by an Issue: While my system is connected, Windows reports that there is No Internet connection.
That can cause issues with applications (cause the vendors use the Windows build in function to figure out if there is an internet connection, or not). In my case, the Microsoft Store causes issues on one system.

Another Problem: I use the PowerShell cmdlet “Get-NetConnectionProfile” to figure out which NIC is used. That fails, because it also uses the Windows build in function to figure that out.

I used the following code before in many of my scripts and functions:
$paramGetNetConnectionProfile = @{
IPv4Connectivity = 'Internet'
ErrorAction = 'Stop'
WarningAction = $SCT
}
$InterfaceAliasInfo = ((Get-NetConnectionProfile @paramGetNetConnectionProfile).InterfaceAlias)
I have replaced that with the following, more complex, code:
$SCT = 'SilentlyContinue' try { $paramGetNetConnectionProfile = @{ IPv4Connectivity = 'Internet' ErrorAction = 'Stop' WarningAction = $SCT } $InterfaceAliasInfo = ((Get-NetConnectionProfile @paramGetNetConnectionProfile).InterfaceAlias) } catch { Write-Warning -Message 'Thanks Microsoft for the crappy NIC handling in Windows 10 20H2' Write-Output -InputObject '' # Cleanup $TestNetConnection = $null # Figure out if we have a working connection $paramTestNetConnection = @{ Port = 443 ErrorAction = $SCT WarningAction = $SCT } $TestNetConnection = (Test-NetConnection @paramTestNetConnection) if ((($TestNetConnection). TcpTestSucceeded) -eq $true) { $InterfaceAliasInfo = (($TestNetConnection). InterfaceAlias) } } $InterfaceAliasInfo
In my case, most of the systems that caused this issues use Intel NIC’s! I have no idea if this is an Intel only issue!
Hi Jörg, seems like MS has confirmed this bug in 2004 and it is related to some services that do a “probe” on the connection (icon :-). I found this as a first workaround, because our first 2004 systems have the same problems :-/ https://www.windowslatest.com/2020/07/18/windows-10-no-internet-connection-problem/
I found a lot of issues with the latest 20H2 builds.
Most are details or smaller stuff, but in general it is annoying!
By the way: And this Registry fix alone haven’t fixed my issues with HP Hardware. I still see it when I connect via copper (LAN) and some WiFi networks, but not all and not all the time.
On my HP Slice, I have it all the time, on the same hardware, but with 10.0.18363.1237 it works fine. And the older version is fine for this device, it is a Teams Rooms Device.
