Last year's global ransomware attack involving 150 countries around the world highlighted the importance of keeping Windows up to date.
Dubbed WannaCry, the ransomware exploited a vulnerability in Microsoft Windows, affecting versions from Windows XP up to Windows 7.
Microsoft was aware of the issue and released a security update soon after to protect users. Customers who didn’t update their machines were vulnerable to attack, and many corporate customers fell victim.
The incident has highlighted the importance of keeping your software up to date by installing security updates..
What is a security update and why do I need to update my machine?
When Microsoft releases an operating system like Windows 10 its job isn’t finished. In today’s world, cyber attacks are increasingly common and perpetrated using sophisticated and ever-changing code. Microsoft has security teams dedicated to keeping its home and business customers safe from malicious attacks.
Microsoft releases regular software updates via Windows Update. These updates perform a number of functions, they can add new features and design changes, but they can provide security fixes
On the second Tuesday of each month (nicknamed Patch Tuesday) Microsoft usually releases a security update to protect customers against the most recent threats.
If you don’t update your machine, then it could be vulnerable to future cyber attacks.
Microsoft gives you the option to install updates automatically, which means you don’t have to worry about searching for them online and installing them manually.
What versions of Windows get security updates?
Microsoft provides concurrent mainstream support and extended support periods for its operating systems after their release.
During the five-year mainstream support period the OS will get regular updates including security improvements and design features. Once this is over the operating system heads into the extended support period, which means it doesn’t get new features, but will get security updates and fixes.
Currently, Windows 10 and Windows 8.1 get mainstream support and Windows 7 is in the extended support period. Windows Vista and Windows XP don’t get either, although in an unprecedented move, Microsoft released a security patch for older versions of Windows.
