NDIS Usermode I/O Protocol


  • Hi all here i am again,
    and this time im in doubt with something...
    the NDIS Usermode I/O Protocol non plug and play service ,i wonder what is it for? i disabled it and realized a huge diference in terms of internet stability!!
    it looks much more stable with that disabled ,does it have anything to do with windows firewall? disabling this service can it cause a security problem?
    thanks in advance,
