After you exit from this you'll find Windows 10 has now enabled developer mode and also enabled support for Subsystems. In order for these changes to take effect you have to reboot the computer.

Once you complete the reboot you can then proceed with the Bash installation. Follow the instructions below for Bash execution on command prompt.

1. Click on Windows logo button.
2. In search bar type "Bash".
3. Click on the "Bash run command" best match option.
4. This should download the "Bash on Windows" from Windows Store. Make sure you're connected to Internet to perform this action.
5. At the end the success message will be shown.

This step installs bash on your Windows 10 computer. You can now go ahead and execute some of the following Bash commands.

windows 10 bash

ls : Lists the directory and files within current directory
pwd : Lists present working directory of terminal.
cd: Changes the directory into specific directory mentioned by you.
cp : Copies content into directory
rm : removes directory or file.

You can go through the bash commands by searching on google. The support for bash doesn't stop at basic commands. You can also execute "Debian" specific commands on this terminal. For example you can install the Linux based software such as gcc on Windows. You can type the following command on your bash terminal to install gcc.

apt-get install gcc

Things you should know

By default the bash shell gives you super user access on terminal. So make sure that you're not running any random bash scripts that you download from the internet. Know what you are downloading and executing on this shell. Make sure you keep the administrator only access for this terminal. This should reduce the issues of running Linux specific virus on your system.
Software installed from Bash shell is restricted to the functionality of the bash shell itself. It can't be executed on any other parts of the Windows for now. In future this may change and you may get more control of the operating system with the shell. You can't use power-shell to interact with software installed from bash shell and vice versa.

This shell is by no means a complete Linux kernel. It is just a terminal being ported to the Windows 10. It has it's own set of limitation due to restrictive nature of Windows core. This shell was ported to windows with the help from Canonical team. That's why it says "Bash on Ubuntu on Window" when you open the bash terminal.

Conclusion

Bash shell on Windows doesn't do much for the core operating system itself. However it let's system admins and power users to use the bash on Windows. It can also be a good tool to learn bash shell scripting on Windows. It can be used for many other Linux specific tasks to be executed from Windows machine.
