Reset the Password in Linux Ubuntu Bash in Windows 10

For those who setup Ubuntu Linux Bash on Windows 10 but forgot what password they used. I set this up quite a while ago on a computer that I seldom use, and I needed to reset my password. Here are the steps I found from Ask Ubuntu.

  1. Run bashand make a note of your Linux username (this need not match your Windows username)
  2. In Windows admin command prompt (Super+X, A) change the default user to root:

    lxrun /setdefaultuser root
    
  3. Now Bash on Ubuntu on Windows logs you in as root without asking password

  4. Use passwd command in Bash to change the user password:

    passwd your_username
    
  5. Change the default user back to your normal user in Windows command prompt

    lxrun /setdefaultuser your_username

windows 10 change password linux ubuntu

Where are my Windows files on Windows Linux Bash?

You'll find the Windows C:\ structure at /mnt/c/ in the Bash environment.

Therefore, USERNAME's Documents directory is located here: 

/mnt/c/Users/USERNAME/Documents/

Where are my Ubuntu Bash files in Windows 10?

In Ubuntu Linux Bash for Windows, the Ubuntu file system root directory

%localappdata%\Lxss\rootfs

or

C:\Users\Username\AppData\Local\Lxss\rootfs

Replace the Username with your Username on Windows.

 

The Ubuntu system files are stored at:

C:\Users\USERNAME\AppData\Local\Lxss\rootfs

 

Your Ubuntu user account’s home folder is stored at:

C:\Users\USERNAME\AppData\Local\Lxss\home\USERNAME

 

The root account’s home folder is stored at:

C:\Users\USERNAME\AppData\Local\Lxss\root
