Updating your operating system

Microsoft makes updates available for various operating systems through the

Microsoft Windows Update Web site. The Web site automatically determines what

Windows updates are available for your specific computer and lists those updates

only. Updates could include security fixes, new versions of Windows components

(such as media player), fixes to other portions of the Windows operating system,

or enhancements.

For more information about updating your operating system, refer to the Access

Help online help system . See “Access Help” on page 40 for instructions on how to

open the online help system.

Installing other operating systems

If you install your own operating system, follow the instructions that come with

your operating system CDs or diskettes. Remember to install all device drivers

after you install your operating system. Installation instructions are usually

provided with the device drivers.

Updating your antivirus software

Your computer comes with antivirus software you can use to detect and eliminate

viruses. Lenovo provides a full version of antivirus software on your hard disk

with a free 90-day subscription. After 90 days, you must get a new virus definition.

For more information about updating your antivirus software, refer to the Access

Help online help system . See “Access Help” on page 40 for instructions on how to

open the online help system.
