auto fill using tab key in cmd not working...

Hello {.}

Please follow these steps

Press “Win + R,” type cmd and press the Enter button to open the command prompt. Once opened, enter the below command and press the Enter button.

cmd /f

If that didn't work

press “Win + R,” type regedit and press the Enter button. This action will open the Windows Registry.

Here, navigate to the following key.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor

Double-click on the key “CompletionChar.” This action will open the Value Data window. Replace the existing value with “9” and click on the “Ok” button to save the changes. This action will set the default control character as the TAB key on your keyboard.

If you want to set “Ctrl + D” as your control character, then enter the value as “4.” If you want to use “Ctrl + F” as your control character, then enter “6” as the value in the value data field.

Replace the existing value with '9.'

Double-click on the key “PathCompletionChar” and enter the value data as “9” for TAB key, “4” for “Ctrl + D” and “6” for “Ctrl + F.” After entering the value data, click on the “Ok” button to save the changes.

However, make sure both keys we just edited have the same value data. Otherwise the configuration won’t work as it should.

That’s all there is to do. From this point forward, you can use the auto-complete feature in Windows Command Prompt by pressing either of the tab keys or CTRL + D or CTRL + F, depending on your configuration.

I hope it helps
