Make PuTTY your default MSWin telnet client
31 Dec 2008
OMG, this has be beating me for some time, until the PuTTY author's site finally gave the details.
I wanted to be able to click on a telnet:// URL from my Hosts Reachable ( http://taurus2.plus.com/ip_reachable.html / http://gb7imk.ampr.org/ip_reachable.html ) webpage and for it to automatically open the telnet connection in PuTTY and not MS messy telnet client.
Here's how I solved it in MSWin XP:-
'Start', 'Run', 'regedit'. <ENTER>
Go to, HKEY_CLASSES_ROOT\telnet\shell\open\command and change the entry to "\path\to\putty.exe %1". Not including the double quotation marks.
Done! Obviously note the original value down in case you wish to set it back again. :)
Happy New Year!
