I tried your TCP/IP tune up guide... and after some testing decided to revert back to my original configuration (I had made a restore point for this).
 
However for reasons known only to itself Windows has removed my restore point (and all the others I had) *%$@ ;( knows why!! since I haven't installed or tweaked anything else today...
 
Anyhow at the end of the guide you have a list of guidelines on repairing a machine if something goes wrong. Now I'm perfectly capable of following them.... it just seems a very long winded way of doing it. Since I only applied the contents of APK1.reg and APK2.reg to the registry. (and didn't change anything else) would it therefore be possible to simply delete the following keys:
 
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
 
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AFD\Parameters]
 
and hope they regenerate on the next reboot?
 
If not do you know the defaults for these off hand... so I don't have to re-install ALL the TCP/IP stuff from scratch... and all the patching it will entail afterwards?
 
Thanks
