hi, i used this method and successfully changed my MTU, thanks so much!
but i have a related question. every time i reboot or shut my computer down and boot it up again later, the MTU settings i adjusted are lost
iím running cmd.exe as administrator and using store=persistent at the end of the command line, but still it keeps resetting itself to MTU=1300 after every (re)boot.
is there anything i can do to save this setting ?
