Each and every virtual or dedicated hosting machine has its own Operating System and works independently from the hosting machines of other customers. Updating the Operating system is often overlooked, but doing that may have lots of benefits for your internet sites. The most important reason to use the most up-to-date version is that patches are frequently released to fix security holes within the Operating System code, so if you do not install the updates, you risk people with destructive intentions to take advantage of these holes and to access your content. OS updates are also released for improved performance of the system overall and for better compatibility with the hardware on the market, which can instantly impact the functionality of your websites. If the performance and the security of your scripts is the reason to update them, you may also discover that their latest versions require an updated Operating System to be able to operate effectively, consequently keeping the Operating system up-to-date is always a good idea.
