Rename on First Boot

Used for linked template VMs via Proxmox.

On boot it pops up, asks for new name, then asks to reboot.

Needs to be set up on the template

Save this script to C:\Scripts\rename-on-clone.ps1 (create the folder if it doesn’t exist):

if ($env:COMPUTERNAME -eq "win11temp") {
    $newName = Read-Host "Enter a name for this machine"
    if ($newName) {
        Unregister-ScheduledTask -TaskName "RenameOnClone" -Confirm:$false
        Rename-Computer -NewName $newName -Force
        $restart = Read-Host "Restart now? (y/n)"
        if ($restart -eq 'y') { Restart-Computer -Force }
    }
}

Then register the scheduled task:

$action  = New-ScheduledTaskAction -Execute "powershell.exe" `
               -Argument '-NoProfile -ExecutionPolicy Bypass -File "C:\Scripts\rename-on-clone.ps1"'
$trigger = New-ScheduledTaskTrigger -AtLogOn
Register-ScheduledTask -TaskName "RenameOnClone" -Action $action -Trigger $trigger -RunLevel Highest -Force

Flow once it’s templated: Spin up clone → log in → PowerShell window pops up → type a name → machine renames and reboots → task deletes itself → never prompts again.
