You can now use the Ubuntu apt or apt-get command to install software from the Ubuntu repositories. The easiest way is to install Ubuntu, one of the most popular Linux distributions, or install multiple Linux distributions, each of which will receive its own unique shortcut. This process is no different from installing any Store app. You will see a list of all Linux distributions currently available in the Windows Store click on the option you want and then click on the Install button. Once the computer boots up, open the Microsoft Store and search for 'Linux'. For the function to work, click on the button 'Restart now'.
Next, enable the 'Windows Subsystem for Linux' option, and then click the 'Apply' button. Now go to the Control Panel, open Programs and Features, and select “Turn Windows features on or off”.
You can only use Bash Shell for Windows 10 on a 64-bit version of Windows 10 keep that in mind.
