​Microsoft released the following Security Bulletin -  This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution (taking control of your computer)  if an attacker sends specially crafted messages to a Microsoft Server Message Block 1.0 (SMBv1) server. 


Microsoft has released separate security patches below for each version of Windows that addresses the threat, see below.


With all of the reports of cyberattacks and hacking taking place, it is smart to take all security precautions to protect yourself. If you have an older computer built prior to 2012, you are particularly at risk. If you are still using a computer running on Windows XP, you have no security protection at all since Microsoft no longer support Windows XP. Contact us for more details on that topic.

This security update is rated Critical for all supported releases of Microsoft Windows.


The Solution:

  • BEFORE INSTALLING. Confirm which version of your operating system you are running (Win 7 64 bit for example) as the downloads are specific to each operating system.
  • Once you click on the Microsoft link, choose your operating system from that list. 
  • It will be a single file that you download, then install with ALL other programs closed.
  • Once complete you will need to reboot, 


Microsoft states that you can protect yourself from this vulnerability by installing the following recent critical update then rebooting your machine. Note these are single security updates not rollups (bundled updates):
