Microsoft Windows is the operating system that controls all the software and hardware operations of your personal computer. Microsoft updates Windows on a regular basis, fixing bugs and patching known security vulnerabilities through a series of critical updates that you can download to your computer.
To maintain a high security level for your PC, you need to ensure that your copy of Windows is regularly updated. Microsoft makes this easy by offering regular updates over the Internet, as part of the Windows Update service. When Windows Update is properly configured, your PC will periodically go online and check against the main Windows Update website, and then automatically download and install any available updates.
