To disable CTCP, don't see why anyone would want to do that but still.. Do the same thing.
Create a new text file, name it DisableCTCP.bat and paste this into it.

@echo off
echo Checking setting
netsh int tcp show global
pause
echo Changing Add-On Congestion Control Provider to NORMAL mode
netsh int tcp set global congestionprovider=none
echo Done!
netsh int tcp show global
pause
exit

---

Now run the file by right clicking and chose " Run as administrator "
