How to set a password on a "local"/non email or online based Windows account or device.

In general, if you sign into an online account, University, Outlook, Gmail, Hotmail or Live etc, a password will automatically be assigned to your Windows user account.

To set up a password in Windows on a "local", non email or online based account, you'll need to navigate to the Sign-in options within the Settings app. 
Under the Password section, you can either "Change" your existing password or "Add" a new one. 
If that does not work:

Open Settings: Click the Start button, then click the gear icon (Settings). Or search Change your Password.
Go to Accounts: Click on "Accounts" in the Settings window. 
Choose Sign-in options: Select "Sign-in options". 
Password Section: In the Sign-in options menu, find the "Password" section. 
Add or Change:
To add a password, click the "Add" button. 
To change an existing password, click the "Change" button. 
Follow the prompts: Enter a new password twice, a password hint, and follow the on-screen instructions to complete the process.
