CMD/Batch get active interface name as variable

Question

I\'m currently having a hard time figuring out how to get the active interface names as a variable output which can be later on used in the code. I\'ve been reading here a bit,

Answer 1

Because the output of WMIC has the 'ugly' line endings and the value of NetConnectionID will often have unwanted trailing spaces, I'd suggest something more like this to retrieve only connected network adapters as variables:

@Echo Off
Set "i=0"
For /F "Skip=1Delims=" %%A In (
 'WMIC NIC Where "NetConnectionStatus=2" Get NetConnectionID'
) Do For /F "Delims=" %%B In ("%%A") Do Call :Sub %%B
Set NIC[
Timeout -1
Exit/B
    :Sub
    Set/A i+=1
    Set "NIC[%i%]=%*"
