How to change network adapter name via command line in windows 7?
Easy enough without PowerShell:
netsh interface set interface name="Old Name" newname="New Name"
Easy enough with PowerShell:
Get-NetAdapter -Name "Old Name" | Rename-NetAdapter -NewName "New Name"
Of course, in PS, you can also select your adapter by whatever property you see fit.
Get-NetAdapter -InterfaceIndex 12 | Rename-NetAdapter -NewName "New Name"
