Blog Post: Reconfigure Hyper-V External switch to the correct network adapter
Wrote a little blog post about how to change the External switch to the correct network adapter, convenient if you use Wi-Fi at the office and a wired connection at home for example. More about that here: https://powershellisfun.com/2022/10/08/reconfigure-hyper-v-external-switch-to-the-correct-network-adapter/ The script: function Set-CorrectHyperVExternalSwitchAdapter { param ( [parameter(Mandatory = $true)][string]$SwitchName ) #Validate SwitchName if (-not (Get-VMSwitch -Name $SwitchName | Where-Object { $_.SwitchType -eq 'External' -and $_.AllowManagementOS -eq $True })) { Write-Warning ("External Hyper-V Switch {0} can't be found or has no 'Allow management operating system to share this network adapter' enabled, exiting..." -f $SwitchName) return } #retrieve external switch(es) with Allow Management OS on and get Network adapter with Up state $externalswitch = Get-VMSwitch | Where-Object { $_.Name -eq $SwitchName -and $_.SwitchType -eq 'External' -and $_.AllowManagementOS -eq $True } $connectedadapter = Get-NetAdapter | Where-Object Status -eq Up | Sort-Object ifIndex | Select-Object -First 1 #Set VMSwitch(es) properties so that the connected adapter is configured try { Set-VMSwitch $externalswitch.Name -NetAdapterName $connectedadapter.Name -ErrorAction Stop Write-Host ("Reconfiguring External Hyper-V Switch {0} to use Network Adapter {1}" -f $SwitchName, $connectedadapter.Name) -ForegroundColor Green } catch { Write-Warning ("Failed reconfiguring External Hyper-V Switch {0} to use Network Adapter {1}" -f $SwitchName, $connectedadapter.Name) } }Blogpost - Creating a Hyper-V VM running Evaluation versions of Windows server using PowerShell

What is difference between File size and Size in the output of GET-VHD command?
In resizing VHD using Resize-VHD command, the property SizeinBytes is accepting value greater than the "Size" property in the output of the GET-VHD command. But my actual size of VHD is in "FileSize" property. I am unable to figure out the relation between File size and Size. I would be glad to know the relation between the FileSize and Size properties or the unit of Size property (Kb/Mb/any other related). Thank you in advanceImp: Unable to remove HyperV in windows 10 using Powershell Script - Urgent
