Change the default telnet client in Windows

I just keep on forgetting what to change to get this working. As I don't want to search everytime I'm just posting a shameless copy from Rene's ICT Notepad.

Enable handling of telnet://hostname:port/ URLs on the command line. With this feature, you can now set PuTTY as the default handler for Telnet URLs

If you run the Registry Editor (Start->Run->regedit.exe) and set the value in:
HKEY_CLASSES_ROOT\telnet\shell\open\command to be: "\path\to\putty.exe" %1
(with the full pathname of your PuTTY executable), you should find that clicking on telnet links in your web browser now runs PuTTY.

This is confirmed to be working for Chrome on Windows 7.

  14. Didn't want to sign up but wanted to thank you for the tip. Getting Chrome to open any sort of telnet app was driving me crazy. Your instructions worked like a champ, and remembering to include the %1 at the end made it pop to the correct site. Thank you!
