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 if you need to share your computer with family members or other users. Step 1. Open the Start menu and select Settings ➙ Accounts ➙ Family & other users. Step 2. Select Add someone else to this PC. © Copyright Lenovo 2020 11 Note: To add family members, you need to sign in with a Microsoft account. Step 3. Set the user name and password for the user account. 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. Select Windows Hello Fingerprint ➙ Set up ➙ Get started. Step 3. Follow on-screen instructions to complete the 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. 12 User Guide Windows desktop Change 1.

Ergonomic information Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort. Arrange your workplace and the equipment you use to suit your individual needs and the kind of work that you perform. In addition, use healthy work habits to maximize your performance and comfort when using your computer. Working in the virtual office might mean adapting to frequent changes in your environment. Adapting to the surrounding light sources, active seating, and the placement of your computer hardware, can help you improve your performance and achieve greater comfort. This example shows someone in a conventional setting. Even when not in such a setting, you can follow many of these tips. Develop good habits, and they will serve you well. General posture: Make minor modifications in your working posture to deter the onset of discomfort caused by long periods of working in the same position. Frequent short breaks from your work also help to prevent minor discomfort associated with your working posture. Appendix B. Accessibility and ergonomic information 43 Display: Position the display to maintain a comfortable viewing distance of 510 mm to 760 mm (20 inches to 30 inches).
