Chapter 2.Get started with your computer
Get started with Windows 10
Learn the basics of Windows 10 and start working with it right away. For more information about Windows
10, see the Windows help information.
Windows account
You must create at least one account to use the Windows operating system. It can be either a local account
or a Microsoft account.
Local accounts
A local account is created on a particular Windows-enabled device and it can only be used on that device. It
is recommended that you set a password for each local account to prevent unauthorized access to the
device.
Microsoft accounts
A Microsoft account is a user account that you use to sign in to Microsoft software and services. If you use
Microsoft services like OneDrive, Outlook.com, Xbox Live, Office 365, and Skype, you might already have
one. If you don't have it, you can create one for free.
There are two main benefits of using a Microsoft account:
• Sign in only once. If you use a Microsoft account to sign in to Windows 10, you don’t need to sign in again
to use OneDrive, Skype, Outlook.com, and other Microsoft services.
• Settings can be synced. If you use your Microsoft account to sign in to multiple Windows-enabled
devices, certain Windows settings can be synced among the devices.
Switch between a local and a Microsoft account
If you are using a local account to sign in to Windows 10, you can switch to use a Microsoft account instead.
Step 1. Open the Start menu and select Settings ➙ Accounts.
Step 2. Select Sign in with a Microsoft account instead.
Step 3. If you already have a Microsoft account, enter the account name and password to sign in.
Otherwise, select Create one to create a new Microsoft account.
Note: The device must have Internet access the first time you use a Microsoft account on that
device.
If you want to switch back to use a local account, open the Start menu and select Settings ➙ Accounts ➙
Sign in with a local account instead.
Add additional user accounts
Your user account must be of the “Administrator” type to add additional user accounts to Windows.
Add additional user accounts if you need to share your computer with family members or other people.
Step 1. Open the Start menu and select Settings ➙ Accounts ➙ Family & other users.
Step 2. Select either Add a family member or Add someone else to this PC.
Note: By default, you are prompted to add Microsoft accounts. If you don’t know the person’s
Microsoft account, select I don’t have this person’s sign-in information. Follow on-screen
instructions to create a Microsoft account for the person. Alternatively, select Add a user without a
Microsoft account to create a local account for the person.
Enroll your fingerprint
If your computer includes a fingerprint reader, you can enroll your fingerprint for Windows sign-in.
Step 1. Open the Start menu and select Settings ➙ Accounts ➙ Sign-in options.
Note: If you are using a local account, the account must be password protected. Otherwise, you
cannot enroll fingerprints.
Step 2. Under Fingerprint, select Set up ➙ Get started.
Step 3. Follow on-screen instructions to complete enrollment. Create a PIN when prompted, in case your
fingerprint cannot be recognized at Windows sign-in.
Note: You can enroll more than one fingerprint.
