This is how you would add a new wireless profile, and then delete the old one.
Note, the NewWireless.txt contains the exported wireless settings from a reference machine
netsh wlan add profile filename=NewWireless.txt user=all
netsh wlan delete profile MyOldWirelessSSID
Create wireless profile in XML
Import XML at the command line

Notes
If you’re going to export the XML, you will have to clear the key. To do this, run
netsh wlan export profile PROFILENAME folder=DIRECTORY key=clear
