Why doesn't TTL change on Windows?

Question

Iron

I change the DefaultTTL registry editor to 65 in the Tcpip and Tcpip6 sections at the same time. I reboot the system, ping the LAN and shows TTL 128. The value remains 65
in the registry. What could be the problem?

Answer 1

In ping, you see the TTL of the response packet, not the one sent from your computer.

Answer 2

In my case, installing ttl via network shell (netsh.exe) worked

netsh int ipv4 set glob defaultcurhoplimit=<value>
netsh int ipv6 set glob defaultcurhoplimit=<value>

No problem, no reboot required. Windows 2004 (build 19041.329).
