Why we need to use Windows Update
Tens, hundreds, even thousands of attempts are made upon your computer every hour! No operating system [Windows, Linux, Apple] is perfect. Hackers 'test' the operating systems every day, looking for vulnerabilities. Each week, and sometimes on a daily basis, certain 'holes' in the OS must be repaired, to prevent the hackers from breaking in.
Windows Update is one such service to the windows user. It is very, VERY, important to the security of your PC to set your computer to automatic updates [recommended]. Or, visit www.windowsupdate.com Weekly.
Finally, do not ignore update alerts from other software like Java and Adobe®. Many forms of Malware 'sneak' in to your PC through 'holes' which are 'patched' by these updates.
