How to disable Windows update notification message of NOD32 Antivirus?

If you are an ESET Node32 antivirus or ESET Smart security (v 4.0) user probably you have got the message ‘Maximum protection may not be ensured" and "Operating system is not up to date’ especially if you disabled automatic update of your OS (in order to prevent any possible update issues). If you find this message is annoying you can simply disable or modify this.

By default, ESET security product notifies you when there are updates available for your operating system. You can modify or disable these notifications.

To get back the Maximum Protection status (green icon), click Protection status from the main menu and then click ‘here’ in the Operating system is not up to date message. Click Run system update and then either update your OS or close the window. (Via)
