Update Windows with latest critical security patches

Windows Update is software designed to help keep your computer current and more secure by downloading and installing the latest security and feature updates from Microsoft.  As a licensed user of Windows you are entitled to software updates to the operating system periodically released by Microsoft. These include upgrades to Windows features, updates that improve reliability and performance, and updates that provide new protections against malware and other potentially unwanted software. Microsoft might also provide updates to software supplied by your computer manufacturer to improve performance or reliability of other software and hardware components on your PC. Windows Update determines which updates are applicable to your computer and can download and install them automatically to keep your computer up to date and more secure.
