Hi Andre! First, I want to thank you for the tutorial, I am "banging my head" because of this problem. Whenever I use a torrent application (Utorrent, Tixati, etc) my computer freezes for 1 to 3 seconds from time to time. I have reinstalled Windows, removed the Anti virus, updated the network card (Realtek 8112L) driver among other things, nothing worked. I think the problem is in "tcpip.sys - function : TcpPeriodicTimeoutHandler" I uploaded the ETL (7z compressed )file to my dropbox folder and sent the link to you in a PM, if you have some time, I would be very grateful to you. Again, many thanks! edit: The Motheboard is a Asus P7P55D-E
