The built-in telnet tool in EVE-NG-Win-Client-Pack is putty.exe, which is small and lightweight, but when there are many devices in the topology, there will be more windows and it is troublesome to switch.
xshell's multi-tab and custom layout are much more convenient to use
You can change it by modifying the registry, save the following code as a .reg file, and add it to the registry (modify the xshell path according to your own installation path)
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\SOFTWARE\Classes\Xshell.telnet]
@="telnet"
[HKEY_CURRENT_USER\SOFTWARE\Classes\Xshell.telnet\DefaultIcon]
@="D:\\Program Files\Xshell Plus\\Xshell.exe,0"
[HKEY_CURRENT_USER\SOFTWARE\Classes\Xshell.telnet\shell]
[HKEY_CURRENT_USER\SOFTWARE\Classes\Xshell.telnet\shell\open]
[HKEY_CURRENT_USER\SOFTWARE\Classes\Xshell.telnet\shell\open\command]
@="\"D:\\Program Files\\Xshell Plus\\Xshell.exe\" -url %1"
[HKEY_CURRENT_USER\SOFTWARE\Xshell]

[HKEY_CURRENT_USER\SOFTWARE\Xshell\Capabilities\URLAssociations]
"telnet"="Xshell.telnet"
[HKEY_CURRENT_USER\SOFTWARE\RegisteredApplications]

[HKEY_CURRENT_USER\SOFTWARE\Classes\telnet\shell]
[HKEY_CURRENT_USER\SOFTWARE\Classes\telnet\shell\open]

[HKEY_CLASSES_ROOT\Xshell.telnet\shell]
[HKEY_CLASSES_ROOT\Xshell.telnet\shell\open]
[HKEY_CLASSES_ROOT\Xshell.telnet\shell\open\command]
@="\"D:\\Program Files\\Xshell Plus\\Xshell.exe\" -url %1"
[HKEY_LOCAL_MACHINE\SOFTWARE\Xshell]
[HKEY_LOCAL_MACHINE\SOFTWARE\Xshell\capabilities]
[HKEY_LOCAL_MACHINE\SOFTWARE\Xshell\capabilities\URLassociations]
"telnet"="Xshell.telnet"
[HKEY_LOCAL_MACHINE\SOFTWARE\RegisteredApplications]
"xshell"="software\\Xshell\\capabilities"
Then click on the telnet device, and the selection window will pop up
