혹 설치후 윈도 시디를 넣으라 뜨면 그냥 취소 시키면 된다.
변경후 재부팅 시키고 p2p나 토렌트를 켠상태에서 인터넷 창을 뛰워보면 확실히 속도가 빨라진것을 느낄수 있을것이다.

Restart of the program can be demanded after updating Windows or SP installation as sometimes Microsoft replaces old file tcpip.sys on new. If the program will cease to work with updated tcpip.sys on this site there will be a new version.
For Vistaand Server 2008users: Probably sometime, after updating Windows or SP installation on a desktop will appear watermarks "Test mode". They can appear because in all versions of Vista and Server 2008, except Vista without SP(x86), there is the obligatory check of the signature of drivers, and the file tcpip.sys sign with test signature after patching.

To check up, whether works on your computer this limit, look in Event Viewer (for example via Control Panel — Administrative Tools; or Start — Run — EventVwr.msc). Each message «EventID 4226: TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts» speaks about that limit has worked.
Usually it means, that the network worm (virus) or any P2P program works on your computer. If such messages in Event Viewer appear very often most likely you sweep up a problem and - you will have difficulties with opening web pages in a browser.
