Microsoft Security Update July 2017

Priority Level: 
12 July 2017

Microsoft released their July security update today. The July release addresses vulnerabilities in Adobe Flash Player, Windows Server 2016, Windows Server 2008, Windows Server 2012, Windows 10, Windows 8.1, Windows RT 8.1, Windows 7, Microsoft Edge and Internet Explorer 11.

What to do now

If these updates haven’t been installed automatically on your Windows computers already, or if you postponed the installation when prompted, install them now.

Note: If you have automatic updates enabled and are using a supported platform such as Windows 7, Windows 8.1 or Windows 10 you should not need to take additional action.


Security updates fix vulnerabilities or weaknesses in computer systems that attackers may try to use to gain unauthorised access or to perform other malicious activity.

Several of the vulnerabilities addressed by this update are ranked 'critical' and could potentially allow an attacker to gain control of an affected system.

Staying safe

Windows Update provides the latest security and other important updates from Microsoft automatically for supported platforms (including updates for Microsoft Office, Internet Explorer and Edge). Automatic updates are turned on by default in Windows 10, and you can switch automatic updates on for Windows 7 and 8.1. Refer to Windows Update for information on how to do this.

If you are using an older, unsupported version of Windows, such as Vista or XP, we strongly recommend updating to a more recent, and more importantly, supported version. Supported versions of Windows receive free regular security updates that are necessary to keep you safe online.
