I have a windows 10 laptop (it's pretty old, but I don't think that should be a problem). I followed the instructions and went through control panel and enabled Telnet Client using an admin password. However, when I launched cmd and typed telnet, I received the error message "telnet could not be recognized as an internal or external command..." I also tried this with an admin-powered cmd and got the same error.
After a bit more of searching, I found a command that should enable telnet. I typed in "dism /online /Enable-Feature /FeatureName:TelnetClient" and it said something like installation complete. However, even after typing telnet into cmd, I got the same error message.
Edit: I located telnet.exe in the System32 folder and if I run it from file explorer directly it works fine. However, when I type in the path in cmd I am getting the same error message. And if I type "start path/telnet.exe" I also get the same error message.
Edit 2: I added system32 to the path variable, but typing "start path/telnet.exe" just gives the error message that it couldn't locate it.
Edit 3: it seems that cmd is not even recognizing the existence of telnet.exe. I followed Binarus' help and typed in dir c:\windows\system32\telnet.exe and am getting file not found. Anyone know what I can do?
